Tick-borne diseases on the rise in multiple US states, warns CDC.

Babesiosis, a tick-borne disease caused by microscopic parasites that infect red blood cells, is now considered endemic across all of New England, according to the Centers for Disease Control and Prevention. The disease causes illness that could range from asymptomatic or mild to severe, or fatal among anyone immunocompromised. Symptoms include fever, muscle and joint pain, and headache, with the possibility of severe complications. The disease is spread by black-legged ticks, which can send the parasites into the bloodstream of any organism it lands on, including people.
