Vector-borne Disease Research

The Challenge: Lyme disease, which is caused by a tick-transmitted spirochete, is the most common vector-borne disease in North America, with about 300,000 cases each year. Most cases occur in the northeastern and north central U.S., with relatively few in the south, even though the vector tick is present in all of these regions. The purpose of this research is to elucidate the ecological...
