Guest essay by Eric Worrall
Zoonotic disease researcher Katharine Walter has claimed that climate is causing a massive rise in human cases of potentially debilitating Lyme Disease. But there are a few problems with this theory.
…
Deer tick invasion
Encounters with ticks didn’t always cast a dark shadow over North American summers. Cases of Lyme disease first appeared in 1976 in the woodsy suburb of Lyme, Connecticut. At that time, deer ticks were found only in a hotbed encircling Long Island Sound, along with a small area in Wisconsin.
Since the 1970s, deer ticks have rapidly extended their reach north, west, and south. The most recent map shows that deer ticks now roam throughout the eastern coastal states, from Maine to Florida, and across the Midwest. They are now established in 45 percent of US counties. That means the deer tick has more than doubled its reach in the 20 years since the previous map was published.
The spread of Lyme disease has closely followed the spread of the forest nymphs. Lyme disease is now the most common disease transmitted by a vector — a mosquito, tick, or other bug — in United States. More than 30,000 cases are reported each year, and the Centers for Disease Control and Prevention estimates that 10 times as many Americans develop the disease.
…
Ticks spend the majority of their lives on the forest floor. They are vulnerable to changing local climates and death by freezing, drowning, or desiccation. Warmer winters and longer summers let more ticks survive and thrive further north each year. Warmer temperatures quicken the tick life cycle, too. Tick eggs hatch sooner and ticks spend more time questing for blood, and so are increasingly likely to feast on a human and pass on a disease-causing pathogen. Because more ticks survive and mature more quickly, diseases can be transmitted faster.

What happened in the early 1970s, which might have caused a sudden rise in the rate of dangerous insect borne disease infections?
In 1962, Rachel Carson published the book Silent Spring. It cataloged the environmental impacts of widespread DDT spraying in the United States and questioned the logic of releasing large amounts of potentially dangerous chemicals into the environment without understanding their effects on the environment or human health. The book claimed that DDT and other pesticides had been shown to cause cancer and that their agricultural use was a threat to wildlife, particularly birds. Its publication was a seminal event for the environmental movement and resulted in a large public outcry that eventually led, in 1972, to a ban on DDT’s agricultural use in the United States. A worldwide ban on agricultural use was formalized under the Stockholm Convention on Persistent Organic Pollutants, but its limited and still-controversial use in disease vector control continues, because of its effectiveness in reducing malarial infections, balanced by environmental and other health concerns.

The timing fits. DDT was banned because of fears about its long term persistence in the environment – its ability to spread and continue killing insects, well beyond the location where it was originally sprayed.
But there are other issues which might have contributed to the “rise” in Lyme disease rates.
Nobody actually knows how many people are infected every year with Lyme disease. Estimates are statistical models, based on the number of people who are diagnosed, which the CDC admits are only a tiny fraction of the number of people they believe are actually infected. The bacterium which causes Lyme wasn’t identified until 1982, when it was described by Willy Burgdorfer. Given the variability of Lyme disease symptoms, any diagnosis prior to 1982 must be considered circumstantial at best. Changes to the quality of diagnosis, of which there have been a number in recent years, could potentially have a significant impact on the number of reported cases.
Each year, approximately 30,000 cases of Lyme disease are reported to CDC by state health departments and the District of Columbia. However, this number does not reflect every case of Lyme disease that is diagnosed in the United States every year.
Surveillance systems provide vital information but they do not capture every illness. Because only a fraction of illnesses are reported, researchers need to estimate the total burden of illness to set public health goals, allocate resources, and measure the economic impact of disease. CDC uses the best data available and makes reasonable adjustments—based on related data, previous study results, and common assumptions—to account for missing pieces of information.
… the number of people diagnosed with Lyme disease based on medical claims information from a large insurance database. In this study, researchers estimated that 329,000 (range 296,000–376,000) cases of Lyme disease occur annually in the United States.

Changes to land management may have also contributed. The ticks which transmit Lyme disease to humans hide in leaf litter. During much of the 20th century, controlled burning was unfashionable – fire departments sought to suppress fires, rather than burn off excess fuel. Policies have varied in different places at different times, so it is difficult to match management policies to tick prevalence, but controlled burning when it occurred likely had a massive impact on the tick lifecycle, by burning the leaf litter in which they hide.
It is not impossible that climate has influenced the distribution of Lyme disease. However, concluding that climate has caused a rise in Lyme disease infections in US and Canadian forests seems dubious, without considering the likely significant impact of other contributing factors, or the very real possibility that much of the apparent rise is a statistical artefact, caused by poor historical diagnosis and reporting.
Update (EW) – Katharine also mentions the rapid rise in deer population as a contributing factor
In part, ticks are following the spread of one of their favorite sources of blood: deer. As deer populations exploded over the last sixty years, thanks to strict hunting laws and the largely predator-free and deer-friendly landscapes in New England and the Midwest, deer ticks followed. However, the steady crawl of ticks north into Canada can’t be explained by deer alone.

The deer population is a factor as well. There are more deer now, than when the white man first arrived.
This is especially true in the eastern US, where much of former farmland has gone back to forest. Perfect habitat for deer.
Nonsense… it’s clearly caused by global warming. As a matter of fact I’ve never seen a paper written with grant money that did not find global warming as the cause.
Unfortunately they are running out of good ideas faster than the ocean of grant money. Here’s an idea to research that will certainly snag some funds. Global warming causes testicular cancer. See what happened right after the 97-98 El Nino? Coincidence? I think not…
https://www.cancercare.on.ca/common/pages/UserFile.aspx?fileId=303160
the ticks are spread by mammals and birds ..it is not only deer. 10 or 15 years ago there was a warm and early spring in northern Ontario and the ticks were so numerous they were killing moose.
the last several years have had cold and late spring warming. the claim that global warming as a cause of increased lyme is a lie.
many claims are false on their face since there has been virtually no warming in the last decade . These fraudsters are jumping the gun blaming something which hasn’t happened for these natural things.
Actually, the white tail deer populations bottomed out in the era of market hunters and end of logging /farmland conversion.At that point (~1870-1900 depending on location) the Eastern US population populations were nearly eliminated. Only the careful State management and reintroduction allowed the current population increase.
Lyme disease is a simple result of the juxtaposition & close proximity of large uncontrolled deer populations and large uncontrolled human populations. That’s the way ALL zoonotic (~wildlife-man) diseases spread most rapidly. We can lost in the weeds of why deer populations are important, why rodent populations are important, why humans in those environments is important but those are just details.
http://www.cdc.gov/lyme/images/maps/map18.jpg
That is exactly what I was taught as an SF medic. White tails have not only increased in number they are living closer to large numbers of humans than ever before as humans move to areas that are prime habitat.
Check out the CDC map of incidence.
http://phenomena.nationalgeographic.com/2015/07/20/map-lyme/
Notice that the NE and parts of WI are where it’s most endemic.
And BTW the classic bulls eye presentation around the lesion as shown in the attached photo is not really classic. It presents that way in less than 50% of the diagnosed cases.
Those are some pretty glaring problems with K Walter’s claims, glaring indeed.
More half azzed academia
I think it is more than that. It is simply following up on the global Health in All Policies (HiAP is the acronym used) determination to inject “the environment” as a factor in all public policy discussions. This 2013 paper that is a guide for state and local governments (glocal as I mentioned yesterday) https://www.apha.org/~/media/files/pdf/factsheets/health_inall_policies_guide_169pages.ashx admits it is to interject Equity as a governmental goal into all discussions of social, economic, and physical environments.
So this is academia doing what pays the bills and brings in grant money from foundations and the feds.
You also need to consider number of diagnostic tests conducted versus positive cases. I suspect that the increase in cases coincides with an increase in testing.
I grew up in the Lowcountry of SC and have been picking ticks (deer and other kinds of ticks as well) off of myself and my dogs since the mid 1960’s. Luckily I have never gotten Lyme disease but several of my dogs have suffered from tick paralysis.
Here in Australia the Government came up with a radical and creative approach to dealing with the disease.
They simply do not acknowledge that it exists.
You think I’m kidding.
Connecticut Lyme disease is very similar to Siberian tick-carried encephalitis, a terrible, often deadly infection that can be stopped only by injection of copious amounts of gamma-globulin very soon after the bite. I had been bitten and had these injections twice; my parents reacted to tick bites with utter horror and panic.
In Siberia, Soviet government tried to cover up the wide spread of tick-carried encephalitis, a disease that damaged the brain and made its victim a barely moving idiot. Just a stroll in the summer forest could be deadly. I remember seeing on the banks of the Inya river, in the 1970s, bushes seething with ticks in such amounts that tips of the branches seemed to be flowing with some black substance.
This had nothing to do with any human activity, because there were as many ticks in the deep regions of taiga as in the forest around the villages and towns. Tick populations seemed to suddenly explode and spread in some years, and then they subsided somewhat. Nobody knows exactly, why, but those tick population explosions are correlated with moose and elk population changes.
Encephalitis endangered all visitors of the Siberian forests in the summer. The only people immune to it were local farming and hunting families who lived there for generations. They drunk fresh goat milk from goats constantly exposed to ticks; over the years this goat milk gradually worked as a vaccine against encephalitis.
Sadly it appears shooting deers and other carriers of ticks would be efficient and cheap way to reduce tick born Lyme disease and encephalitis, but those stupid greens are paralysed when you talk about reducing populations of those.
“In Siberia, Soviet government tried to cover up the wide spread of tick-carried encephalitis, a disease that damaged the brain and made its victim a barely moving idiot.”
Yamal is in Siberia. How long was Briffa in Yamal? Could that explain his results? /sarc
Hugs:
It is far more efficient to spread insecticide treated cotton puffs through host woodlands to kill of the new generations of ticks. Ticks use mice to overwinter.

Simple preventative measures like closing off places of entry in clothing and avoiding game trails where the ticks are most likely to be concentrated and “quest” are the best measures for personal protection.
Here in Indiana a few years ago the white tail population exploded. The state authorized out of season organized hunts even in state parks because the deer were starving. The meat from the hunts was distributed to the needy. But PETA and others showed up to protest and made a big stink about it.
To me PETA stands for People Eating Tasty Animals.
That HiAP link I just put up details the history and calls particular attention to the 2010 Adelaide Statement for South Australia. It is essentially using governments at all levels to force Marx’s Human Development Society using data and outcomes. The M word is never used, but I have spent too much time with Uncle Karl not to recognize the tenets of his vision.
Wife had Lyme-took years for her to find treatment-this was Oregon. She went to
a D.O. in Idaho who prescribed a Brazilian herbal treatment called “Cats Claw”
very effective took about 1 year.
You can buy it over the counter at health/food, etc. stores.
There is science behind it…
I believe some doctors are now pressing for acknowledgement of the disease .
And off topic looks like us Aussies are in for another Labour / Green goverment , and another carbon tax .
There is already a carbon tax. Was introduced yesterday.
My Wife got bit by a Lone Star Tick here in Virginia back in March and she developed Limes from that and had to go on Meds for 4 weeks. She still has a swollen place where the bite is and it flares up about every other week. It’s said that it will possibly take as long as 6 months for the meds to finally take care of it.
Sorry to hear that, I hope your wife has a speedy recovery.
I got bitten by an Aussie paralysis tick in 2012, pretty scary waiting to see if I got sick. Thankfully in my case just a nasty bite, without other complications.
I got bitten by ticks shortly after I got here about 8 years ago.
I now have a recurring bout of achy/exhaustion/flu type symptoms, which last about ten days…once a year.
In case you’re worried about me…it’s OK…I just muddle through!
I’m here in CT where Lyme disease was first recognized. Prior to 1980, a large percentage of the state was still open farmland, mostly planted with hay, grazed by cattle, or growing corn for silage. Many of the farmers annually burned these fields. Today, CT has more forest cover than at any time since the 17th Century, people constantly plant more ornamentals right up against their houses, and bark-mulching is commonplace in gardens, roadsides, etc. Why WOULDN’T there be ticks?
Last winter was the mildest in years; in fact, since the last “big” El Nino in 1997. I have never seen FEWER ticks than we’ve had this past Spring, and those we saw were dog ticks, not the deer ticks that carry Lyme.
I have plenty of opportunity to find them, with 22 horses and 5 dogs! We have had MUCH worse tick seasons following some of the harshest, snowy winters so in my view this “study” is off base. It’s also true that only a very small percentage of deer ticks are even carrying the disease, but people looking for grants have to foment hysteria.
Goldrider….why would a “scientist” studying tick distribution bother to interview people who due to circumstance and avocation be positioned to make observations such as yours? My god man that would be like asking Eskimos about polar bears and seal populations.
Walter has apparently never heard of post hoc, ergo propter hoc. Yes, Lyme disease increased since 1976, and so did temperature. The problem is the disease wasn’t named before 1976, and no test existed before 1982, so the baseline is a great big guess. The increase is another estimate.
Seems just like climate science in general.
Aha! Ticks cause global warming. I knew those bugs were up to no good!
@ur momisugly jon
No, no, no, you have it wrong. Global Warming causes ticks. More irrefutable proof of Lysenkoism and the glory of communist science. 🙂

Katharine Walter’s article only says climate change is speeding up the spread, not that it’s the only cause.
As with many environmental changes, there can be climate and non-climate influences.
Katharine mentions the rapid rise in deer population and climate. As far as I can tell the rise in deer population is only mentioned once – most of the article is devoted to climate.
I’d shoot the deers at my backyard, if that wasn’t illegal (heavily fined, all guns confiscated, deer confiscated).
I’d sure like to know where this “rapid rise” in annual temperature is taking place. With the exception of the past El Nino year, the winters here in CT have been notably cold and wet.
The title of Katharine’s article is “Climate change is SPEEDING UP the spread of lime disease”.
You’re own title is misleading because it gives the false impression that Katharine is claiming that climate change is the only influence. She’s not saying that. Seems like you’re trying to build a strawman here!
Many states have enacted laws to allow deer populations to increase dramatically. Compared to the 1970s, areas which almost never had a wild deer sighting now have small herds routinely to the point where they’ve become pests that destroy gardens and field crops. Additionally, some states have re-introduced large elk populations. There’s just lots and lots of human created food for these things to feed upon.
Katharine also mentioned the rise in deer population, I’ve updated the post to show this.
Cedarhill, absolutely right you are with your statement of:
And that is why it’s referred to as a ……………….
Not a dog tick, nor a wood tick, but a (White Tail) deer tick (the blacklegged tick) because the explosion in the White Tail deer population that began in the 1970’s provided the blacklegged tick a means of easy migration to far distant locations in all directions.
For instance, pre-1970 the deer population in West Virginia was scares, to say the least, and in many locales just the sighting of a deer in a field or running across a roadway was worthy of mentioning in the local newspapers.
But all of that changed with the construction of the Interstate System, especially I-79 from Charleston, WV to Erie, PA …… and I-77 from Columbia, SC (thru WV) to Cleveland, OH.
And you ask, …. “Just how did Interstate construction affect the White Tail deer population?”
And the answer is a simple one. Because it was mandated that all Interstate right-of-ways be reclaimed and reseeded with Crown Vetch …… and the deer loved it, and they ate, and they grew fat and multiplied. And WV and PA are now noted as having the highest yearly “deer kill” by automobiles.
Like most all species of animals, when the local population of deer becomes too crowded, individuals will begin migrating far and wide, carrying those blacklegged ticks along for the ride.
HA, the Interstate System provided the “corridors” for the blacklegged tick (Ixodes scapularis) to migrate along to greener pastures.
Migratory robins have been noted with nymphs around their eyes. I believe that birds are the most effective transport of ticks.
In at least part of PA, the role of Crown Vetch in attracting deer to roadsides has been recognized, and the plant has been removed from many of the right of ways. I do not know if it is state policy or local policies so I cannot say if this is the practice everywhere. Much, if not all of Rte 15 is no longer lined with Crown Vetch. This is a bit sad because it really was pretty. I do think that deer roadkill has decreased, but I travel to PA less often now.
Crown Vetch was introduced as an erosion control measure. Now we deal with the law of unintended consequences.
Crown vetch has been the bane of my efforts as a daylily gardener; it grows everywhere, blooms and seeds in mere moments, and insinuates itself between and among already-established plants. I have seen it planted in masses along roadsides, and–indeed–it is pretty, for the few days it blooms. But it is one of the quickest garden thugs and invaders to establish itself, and I would (given the power) outlaw it on public roadways.
Deer are another problem. One of my best friends in daylilies–who once headed the committee to host the national convention–has had to quit daylilies because the deer came and ate them down to the ground. We are in a metropolitan area, so shooting them is out of the question. (I once read the New Hampshire solution to too many deer: “Veni, vidi, (boom!) venison!” with, of course, apologies to Caesar.)
Day lilies are pretty tasty. .
The same thought occurred to me. My family lives in the North Alabama/Eastern Tennessee area. The deer populations have exploded since ’76. In no small part this is due to lower hunting pressure. For example in the ’70’s most young southern men went hunting after school in the fall… meaning, gasp, we had guns in our cars at school. Between the point the schools let out and sunset the gunfire was strong enough to mimic a small war.
Now days, far fewer students hunt after school… as measured by the level of gunfire and the increased number of deer on our property & in the general area.
Other factors impacting tick levels here are the regulatory hoops needed to get a burn permit. We used to burn our property annually to remove leaf litter, standing grass, vines, to replenish soil alkalinity. and get rid of ticks and other pests. This was done at our discretion when the weather permitted (meaning shortly after a good rain) and when we had the time. With 50 acres and only two adult males in the family this was enough of a chore. Now, it’s virtually impossible to do this routine maintence considering the regulatory hoops you have to go thru to get a burn permits. Theses permits requirements were mostly initiated by states in response to federal environmental air regulations (i.e. the EPA’s CAIR and CSAPR air rules).
Now days, far fewer teenagers and under 30’ers have access to a sporting gun, let alone going hunting at any time of the year. It is no longer PC to be shooting at Bambi.

Use to be, one (1) deer, a buck only, was all you were licensed to kill per hunting season.
Now, in some locales, if you purchase all of the permits you can kill a max of six (6) deet, bucks or does.
I talked to a deer expert here in VA, and he said that when hunters were surveyed about how many deer they would take if the tags were increased, they gave the same number: 2. A lot of them could not used more venison than they would get from 2 deer, and could not afford (or did not want) to pay $90+ a deer to have it butchered. There is a program called Hunters for the Hungry that donates venison to food banks and takes donations to help pay the butchering fees.
Not sure if this is still the case, but school used to be canceled on the first day of deer season in central PA. Easier to do that kind of thing in rural areas where people farm and realized that meat does not magically appear in styrofoam trays at the grocery store.
I don’t know about schools but many businesses in PA allow their employees to have the first day of the season off.
‘The spread of Lyme disease has closely followed the spread of the forest nymphs.’
Ticks are not nymphs. Not even close. Arachnid vs insect. What a maroon.
Deer tick – egg, larva, nymph, and adult – that’s correct life cycle names.
I agree with the other comments, in the UK as much as anywhere else there is a massive uncontrolled increase in deer and improved diagnosis rates – that’s all that is behind the apparent increase. The Winters on the central EU continent are far harsher than the UK, yet forested/deer populated areas have a much worse problem!
Thanks, you are correct about the stages.
Do you have any idea why she calls them “forest nymphs,” as they feed as larva, nymph, and adult? Is Lyme Disease only transmitted by the nymphs?
“Most humans are infected through the bites of immature ticks called nymphs (~2mm so very small). ” (US Dept. of health & human services Lyme disease leaflet). Adult ticks also infect but easier to see.
After they’ve over-wintered the nymphs hang around in leaf litter and low level vegetation, most commonly in forested areas, waiting for a host to happen by. I think that’s why they refer to them as forest nymphs.
Another ‘researcher’ abuses statistics to tell him things s/he doesn’t know because s/he doesn’t have the real world data to stand on, and then stretches to tell us more than what s/he really knows.
Here in Central Florida, where no global warming has happened, there was a young man whom I taught who had mysterious symptoms. Several diagnoses where made by prestigious medical outfits as well as individual doctors here in central Florida. Finally, they said let’s just call it Lyme disease. And let’s say his sister has it too. (she really did not have any symptoms but, hey, why not?)
Now heck, the boy may indeed have Lyme disease and will for years and years (into this 3 years now). But, he might have something else like several outfits first claimed.
Is Lyme disease becoming a “go to” disease?
Lyme disease is a diagnosis that you have to consider when someone presents with complaints that are long lasting and involve multiple systems. Here in Virginia where I was born in 1952 and grew up on a farm and now practice ER medicine it is not uncommon to see the rash pictured above. That represents the early stage of the disease where the bacteria is spreading in the skin but is not systemic yet. Not everyone with a rash like that remembers having had a tick bite and not every case of Lyme has a rash so it gets tricky. The CDC states the Lone Star tick does not transmit Lyme disease but causes another problem with a rash very similar to Lyme disease called STARI.
Ixoides deer ticks have a wonderfully complicated and fine tuned life cycle, fine tuned to allow the previous generation to infect the hosts of the succeeding generation.
A larva or nymph travels on its own only meters, 100 millimeters up and down a blade of grass from its questing site to rehydrate and back, for about 100 days to starvation or desiccation. The adult survives much the same way and duration but with regular meter long vertical travel.
ALL of the horizontal travel is on the back of a host mouse, deer, occasionally a bird or lizard. Avoid deer trails, lawns, meadows and verges to avoid ticks.
Ixoides are not affected by temperature variation, having originated in the Paleartic taiga. Their stressors are desiccation and starvation.
To control Borreliosis and Lyme disease, control the white footed deer mouse, the obligate vector host. To control the mouse, introduce and protect the fox. Deer control is ineffective, demonstrated and proven. Tick Tubes® by Dammnix are effective and expensive Permethrin acaricide infused mouse bedding material.
Ecology and environmental management of Lyme disease, edited by Howard S. Ginsberg (1993 Rutgers)
Shoot the introduced deers. The foxes we have.
Deer populations replenish to consume the available resources. Controlling deer population is the traditional fix for Lyme prevalence, still ineffective after all these years. Eliminate the mice and eliminate the infection.
Here’s a thought; Ixodes tick larvae and nymphs are as likely to hop off their mouse in YOUR house as in the yard. Gravid momma ticks don’t hop off their deer in your house.
Stlll shoot the deers. The problem started here after the introduced deers became common; there are no ticks if there are no carriers for adult ticks.
Getting a cat to kill mice would help of course. The number of cats in my neighbourhood has been declining.
That’s rediculous.
Doug, thanks finally someone who uses the word deer correctly.
I had also mentioned the increase in the deer population, but that post seems to have gotten lost.
But, US deer populations now, are higher than when Liz Warren white ancestors first came to America. Especially in the east, where farmland has reverted to forest.
But, but, when Liz Warren’s white ancestors first came to America the land east of the Mississippi River was heavily forested and thus the population of Deer and Elk was quite small because they are both “browsers” and there is nothing in a forest for them to eat.
And that Deer and Elk population began to diminish simply because the European immigrants shot and killed them whenever they needed “food for the table”. And Deer and Elk meat was served/sold in the Inns and hotels. As the forest gave way to the farmland then the Deer population began to recover. Currently, the White Tail deer populations prefers urban and suburban living where the “eatin” is good and they are protected from their human predators.
Identification of B. Burgdorferi and diagnosis of Borreliosis/Lyme disease is difficult and expensive, a two step process of ELISA and Western Blot test. Presumptive treatment with a full course of common antibiotics eliminates the vast majority of infections. The chronic infections are a different matter and quite intractable, susceptible to political manipulation.
Correct about the diagnosis. Laboratory diagnosis is laborious and error-prone, and clinical signs are often uncharacteristic or ambiguous; chronic sufferers are often mis-diagnosed as hypochondriacs. It is quite likely that, over the years, rising awareness triggered more frequent diagnostic requests, leading to greater case numbers. I thus wouldn’t take reports of rising frequency at face value.
Chronic cases CAN be treated — they just have to be diligently treated for a long time, much like chronic syphilis.
I can hear the screams now, “Chronic Lyme is like syphilis!” Oh, the horror. Oh, the humanity.
Well, the mode of transmission is different, but the bacterial pathogens and the affected organ manifestations (nervous systems) are similar. Generally speaking, infections of the nervous system tend to require prolonged treatment.
There is zero medical science to support the belief that long term antibiotic therapy is beneficial. In fact, there is the opposite, numerous gold standard clinical trials with randomized therapy, where the treated group has outcomes identical to the placebo control group.
If you’re talking about long term treatment of symptoms with things other than antibiotics, I guess people can take whatever witches brew they think helps.
If I thought I might have Lyme disease, I would go to an infectious disease specialist, but not someone who only treats lyme. I would take a full 4 week course of doxycycline. And I would take the cdc 2 step test, then the c6 peptide test if the 2 step was at all uncertain. My goal would be to rule OUT lyme disease, not the opposite. And there’s no way I would let someone put me at risk with long term antibiotic therapy.
In my experience, the “chronic” infections, which are nearly always ambiguous diagnoses, only seem to occur in older white women who would otherwise present with “fibromyalgia,” “chronic fatigue” or garden-variety depression. NEVER ONCE have I heard of a Mexican landscaper coming up with more than an obvious acute Lyme–and who do you think does 95% of the work outside here?
Two good points.
The most susceptible populations are adolescents too distracted to do an effective search for a tick, and senior recreating outdoors, gardening, but with too poor eyesight to see the ~ 1 mm nymph or ~ 2 mm adult.
The hyperbolic headlines featuring a monstrously magnified adult tick are a gross disservice. Only an entomologist microscopist will ever see that image live.
The landscaper cannot afford hypochondria.
Well, my niece had it at age 10. She was misdiagnosed as a hypochondriac for more than a year before the diagnosis was made, and a cure was effected with proper antibiotic therapy. She is white, though, so you are half right.
Of course not all patients with uncharacteristic symptoms and complaints that might suggest Lyme disease actually have Lyme disease. Thanks for pointing that out, Captain Obvious.
In my experience here in Northern California , both male landscapers and male Forestry workers often contract Lyme.Like many men however, they tend suffer in silence. In the case of the 19 y/o male landscaper who contracted his case in Sonoma County, his Lyme was misdiagnosed as cancer of his knee. Right before they were going to amputate his leg they decided to test him for Lyme (at that point almost two years since his symptoms first started) and he was positive. He was treated for the Lyme for almost a year, and his “cancer” was non-existent. The 45y/o Forestry worker from Mendocino county was also misdiagnosed until he almost died. He continues to have symptoms that flare up and it has been 20 years. We don’t exactly live in the backwoods here, but it is misdiagnosed so often it is scary. Worst of all, contrary to popular opinion, the age group that is misdiagnosed the most are young males ages 5-9. You are sort of right though. “Chronic Fatigue Syndrome” and “Fibromyalgia” are often misdiagnoses of late disseminated Lyme and given to people who were never tested for Lyme when they first experienced symptoms. Ticks can carry multiple human pathogens besides Borrellia, and many people have co-infections, such as Stari, Rickettsia 364D, Borrellia Miyamotoi, and Bartonella. Pathogenic Borrellia species have been found everywhere except Antarctica. Even the CDC had to acknowledge just recently that probably only 1in 10 human cases is diagnosed and reported in the US, which means it is far more common than things like breast cancer, which no one laughs at. It really isn’t something to joke about. The ‘science’ of tick borne disease is just about as messed up and politicized as climate “science”, as the Australian commenter above also posted.
By far the most prevalent symptom is the bulls eye rash, but most that self diagnose as lyme never had that. The next most common symptom by far is arthritis. The neurological symptoms are extremely rare in comparison.
Yet those who self diagnose almost always cite fatigue or trouble sleeping or whatever else non specific ailments they have at the moment. And the quacks trying to drum up business always start with the rare symptoms almost everyone has at one time or another, they don’t ask about the common lyme symptoms that most people don’t have.
I see billboards in my neighborhood, in a state which has the lowest risk of lyme according to the maps. If they’re here, I imagine they are everywhere, and lyme isn’t everywhere.

Centuries ago, it was witchcraft, now it’s “climate change”. Progress.
Since 1885, the average temperature of the contiguous US has increased overall perhaps 1F or less. There was a slight decline up to about 1970 and a small rise since then. See NOAA for the data. Such a small nationwide change, which is far far less than the average temperature difference between northern states such as Maine (41F) and and southern states such as Florida (71F), seems to me to be an unlikely contributor to the spread of ticks, deer, Lyme Disease or any other animal or disease for that matter. If the disease is really spreading, we need to look at other causes such as land use changes, introduction of non-native animals, or something else if a fix is to be found. Blaming it on “climate change” simply diverts the attention of our researchers and is harmful.
Yes but it’s great for “climate” funding.
Lyme disease increase is caused by rampant, uncontrolled deer populations, not global warming.
And in some areas deer are becoming far too comfortable around humans. We have two mature does in the area that won’t leave the yard with anything short of attacking them with a baseball bat or stun-gun.
Deer are a resource. Mice are valueless. Deer are visible to hysterics, while mice are not. Deer cannot be eliminated. Mice can be eliminated and rid of Bb infection. Deer control has proven ineffective, difficult and expensive.
Doug, You bring up a good point that it isn’t the deer but the mice as a critical link. But the statement “Mice can be eliminated…” is a bit much.
Both deer and mice can be controlled, but with unequal effort. In the case of mice, more raptors, coyotes, fox, lynx and cats. In the case of deer, more wolves and hunters. The mice will be far harder to control and eliminate than the deer. Eliminating the deer wont solve the Lyme problem if birds are an important agent of geographic spread.
Ahhh …but mice DO have value …you grind them up (the whole thing ) and put them in your tacos that are being stolen from the cooler at work….. and then after a week you include a note with the tacos …..YOUV’E BEEN EATING MICE !…end of stolen lunches !
… SWEEET …
“Climate is causing a Rapid Rise in Lyme Disease Infections”
maybe so but there is no evidence to relate that to fossil fuel emissions

The standard test for Lyme Disease is so unreliable as to be almost useless. The
experienced Dr.s treat the symptoms, but this can also be unreliable. My wife
was diagnosed with the disease and took high dose Doxycycline for three month.
The spirochetes are analogous to fleas in that you have to kill the mature then in a later
cycle, kill the offspring. The origina practice of 2 wks of tetracycline only works in cases
where it is caught very early.
Miss diagnosis is rampant. My neighbor was initaly diagnosed with Lyme, but later
confirmed as ALS.
Deer in my neighborhood are becoming pests. It is not unommon to see 12 whitetails
grazing on my lawn at dusk. I live in E. Tenn.
I know that C is not C, but deer are so unafraid that they now stare at me as drive
by in daylight.
Pemethrin and increased doe harvest may be the answer.

I was just refreshing my layperson’s recollection of the Western Blot test, and my search engine (not Gargoyle) included Morgellons on the same hit parade.
There has been some evidence recently published that Borrellia spirochetes have been found in skin scrapings of people with Morgellons : https://bmcdermatol.biomedcentral.com/articles/10.1186/s12895-015-0023-0
The Western Blot for Lyme was one of the first things to become politicized, when original researchers eliminated two of the potentially positive bands so they could develop LYMErix vaccine. That was a few decades ago.
From the article: “n part, ticks are following the spread of one of their favorite sources of blood: deer.”
There’s your answer right there. Deer move around a *lot*. It has nothing to do with AGW/CAGW.
The way I look at it the more they blame climate on everything, the more it discredits them. They are just flinging crap at the wall to see what sticks, as far as I know none of it has actually been proven right.
Declining numbers of hunters, decreased area hunters are allowed to hunt, increased penetration into deer habitat by suburbia, great lush food sources planted by suburban homes, deer adapting to human interaction and people exploring more into “the wild” by bike, hike, and camping. Yet they can’t figure out why there are more deer ticks. I wish my job paid lots of money for being an absolute moron.
My wife pointed out that Chris Kristofferson was reported to have been diagnosed
and treated for Alzheimers for several years before properly diagnosed with
Lyme. After treatment, he returned to normal.
The spirochetes can settle anywhere in the body. In my wife’s case, they settled
in her elbows and feet. The residual symptoms are arthritis like but can be treated
with very agressive massage after the spirochetes are killed.
I suspect that many cases of dementia and arthriris and possibly other diseases
are misdiagnosed lyme.
