This is a good article describing the emerging, tick-borne Powassan virus in Connecticut. The article also provides a bit of history about the discovery of Lyme disease, also in Connecticut. Reported cases of Powassan are nowhere near the reported number of cases of Lyme, but the numbers are increasing.
"Between 2011-20, in addition to Connecticut, the following states have reported cases to the CDC: Indiana, Maine, Massachusetts, Minnesota, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Pennsylvania, Rhode Island and Wisconsin." The AT runs through 7 of these states.
When I hiked the trail in 2006, I recall numerous conversations regarding bears. Fear of bears. Bear sightings. Bears stealing food, etc. But no conversations about ticks until I ran into two SOBO hikers in New England who had started NOBO in the spring. We recognized each other and stopped for brief chats. Both said they had to get off the trail due to illness from tick bites and felt well enough to flip by the end of summer.
I hiked 1800 AT miles in 2006. I had 9 bear encounters. I did not see a single tick. I completed the trail in 2008 and again, did not see any ticks. I realize that I was very fortunate.
Insect repellents work to some degree against ticks. For me tho, spraying Sawyer Permethrin on my clothing was the most beneficial protection.
