Lone star ticks and alpha-gal syndrome
The lone star tick is established in Virginia in 65 of 132 counties (see the table above). Its bite can cause alpha-gal syndrome, an allergy to red meat.
Do not overlook the tiny ones
Nymph deer ticks are the size of a poppy seed and cause most Lyme cases in Virginia because they are so easy to miss. When you check for ticks, look for the small ones too, especially in June and July.
