A little-known but potentially devastating roundworm infection that can spread from North American raccoons to humans appears to be widening its reach within the United States.
The CDC has reported that while only 22 US cases of baylisascariasis, caused by the Baylisascaris procyonis roundworm, were documented from 1973 to 2010, another 7 cases were diagnosed between May 2013 and December 2015. Since 2002, infections have been reported in Florida and Georgia, outside of the Midwestern, Northeastern, and West Coast regions where they’re usually found.
