Thanks Steve,
There’s also a strong correlation with mast production and the subsequent rodent population booms. For my immediate area, the past TWO YEARS have produced an overabundance of acorns. The time lag is 1 to 2 years after a 'mast year’. This is shaping up to be a really bad year from many reports despite the cold winter…and this would suggest next year also.
For peace of mind, I always save a tick if it was attached for a while and even slightly engorged (never save in scotch tape!). There are tick-testing labs that will do full workups on the tick using PCR. I don’t send every one off. But if I should start feeling ill, my backup is to send the tick off for testing in addition to a doctor visit. It is more reliable to test the source of the disease than to try and figure out the disease(s) in humans. I’ve used this company out of Amherst MA for years and have been very satisfied with their service: https://www.tickreport.com/ <https://www.tickreport.com/> But there are many out there. I’m not sure how a physician would respond if I sent them my tick report?? Fortunately, I’ve never had to.
There are also companies who will treat your personal clothing with pyrethrum as another option.
My heart goes out to anyone who has dealt with any tick-borne disease.

There are now several tick infections that can impact us up here. It's NOT JUST LYME DISEASE ANYMORE. So, I decided to try to educate myself again, and am taking this opportunity to put together some information for everyone. TO THE BEST OF MY KNOWLEDGE:

Dog Ticks can carry Rocky Mountain Spotted Fever and Tularemia (both very serious), but almost all occurrences appear to come from Cape Cod and the Islands. The Lone Star Tick is advancing northeastward and can now be found in Massachusetts, but, again, mostly confined to Cape Cod and the Islands. The strange and potentially deadly "Alpha Gal Symdrome" causes a red meat allergy, but so far seems to be only transmitted by the Lone Star Tick and so should not (currently) be a problem in NH. There are currently 5 infections, all from Deer Ticks to be concerned about in New Hampshire. See discussion below.

> ---------------
> * Deer ticks, or Eastern Black-legged Ticks (Ixodes scapularis) is the only species of "Deer Tick" around here. They are most common in southeastern NH, but can be found everywhere south of the White Mountains. It still appears to be scarce north of the White Mountains? They can be locally abundant, and for some reason, quite variable from year to year. Warmer winters seem to be a factor.

> * Deer ticks go through a two-year life cycle including 4 stages of life (egg, larva, nymph, adult). The egg and larva stage are harmless. Diseases are only transmitted in the nymph and adult stages. Larva (incredibly small) are hatched from their egg without Lyme disease, but many acquire it from their host.

> * Adult Deer Ticks are most easily seen and removed, but are still very small compared to Dog Ticks. They are also very quick to grab on and bite you. They are chasing deer (and humans) which are their primary host species as adults. Only the female adults bite you as the males are just out looking for females. Adults hang out at about knee-high elevation on low branches and shrubs. They can be active all year (even in winter!), but are most active in early spring and later in the fall.

> * Nymphs are active from May through July, but perhaps most active in June...generally after the adults. They are out looking for chipmunks and white-footed mice, but also will readily bite humans. They are VERY SMALL and hard to see. I think I've only seen one once! But that makes them more dangerous as they can bite you and you don't even know it. The nymph stage is reported to be responsible for most of the human cases of Lyme Disease cases in Massachusetts.

> -------------------------------------------
> * Lyme Disease bacteria - Lyme Disease is still the most common tick-transmitted disease and cases continues to grow in the Northeastern United States with 1,563 new cases in NH in 2021. There are initial symptoms for Lyme Disease (bullseye rash), but sometimes they are not present. Doctors often will prescribe an easy single-dose treatment of an antibiotic as a prophylactic if you find the tick before symptoms appear. If the disease goes undetected and untreated, it can sometimes cause long-term problems. Approximately 25% of nymph Deer Ticks carry Lyme Disease and 50% of adults carry Lyme Disease. Although Nymphs are less likely to carry the disease, they are the most likely to transmit it due to their difficulty in detection.

> * Anaplasmosis bacteria (HGA) - About 10% of people with Lyme Disease will also have Anasplasmosis as a co-infection. Tick must be attached for over 24 hours in order to transmit the bacteria. Causes flu-like symptoms 1-2 weeks after a bite. Fortunately, it is treated just like Lyme Disease with an antibiotic. Can be dangerous in elderly or people with compromised immune system.
>
> * Babesiosis parasite - Most common in MA, but increasing. Usually not fatal, but flu-like symptoms can last several months and can be more severe in elderly or people with compromised immune system. Can be treated if caught early. Tick must be attached for 24-36 hours in order to transmit the parasite.
>
> * Powassan virus - Fairly rare, but increasing. 61 cases detected in 10 years in MA and at least 8 detected in NH. Most people don't have symptoms, but For those with severe cases, there is no treatment and up to 10% of people WILL DIE. . Ticks may not need to be attached for very long.

> * Borrelia miyamotoi bacteria (HTRF). Not a lot known (first described in 1995), but apparently much less common than Lyme. Presents flu-like symptoms 2 weeks after bite and does not appear to be generally serious. Treated with antibiotics.
