Of reported cases, 96% occurred in 13 states, particularly the northeastern U.S. are diagnosed with Lyme disease, a significant increase from 2012 estimates of 30,000 reported cases. In August 2013, preliminary results from 3 complementary studies conducted through the Centers for Disease Control and Prevention (CDC) suggested that approximately 300,000 people in the U.S. PREVALENCE & DISTRIBUTION Human Prevalence In recent years, increased deer tick populations are believed to be a result of similarly increased deer populations. They are, instead, blood-feeding stations (and transport vehicles) for adult black-legged ticks. White-tailed deer-often associated with Lyme disease-are not reservoirs for B burgdorferi. The black-legged tick, or deer tick, which parasitizes the mammalian and avian hosts, unwittingly serves as a vector of B burgdorferi to other mammals, including dogs and humans. The host-associated bacteria- Borrelia burgdorferi, a spirochete-is maintained in a variety of wild animal reservoirs, ranging from rodents (principally the white-footed mouse), other small mammals (eg, chipmunks), and ground feeding birds (eg, American robin). ![]()
