EPA funds ground-breaking Lyme disease research

New York, NY In the United States, Lyme disease is the most frequently reported disease that can be passed from animals to humans. These animal-borne diseases can make people very sick, and proper anticipation of disease outbreaks and effective intervention are crucial to protecting the public. S...

A new view on Lyme disease: Rodents hold the key to annual risk

In the United States, Lyme disease incidence has skyrocketed from 497 cases reported in 1982 (the first year national statistics were collected) to a record 23,763 in 2002. Lyme disease, like other zoonoses, is transmitted by a vector that picks up the pathogen during a blood meal from a verte...
