The blacklegged tick is known to carry the bacterium that causes Lyme disease, but also carries Anaplasma phagocytophilum, which causes anaplasmosis.
Onondaga County health officials are monitoring the emergence of a typically rare tick-borne disease that can cause serious illness if left untreated. It’s called anaplasmosis, and it’s a bacterium spread by the same tick that carries Lyme disease. County health commissioner Dr. Indu Gupta says in the previous five years, three cases were reported. So far this year, there have been six.
"We were concerned the way the number jumped. Logically, we can think people have been cooped up inside, went out and probably did not take that many precautions. They got the tick bite, and did not see anything because there was no rash."
