FOX NEWS - Every state in the nation reported residents who tested positive for Lyme disease, according to the most recent Quest Diagnostics study released last week.
No longer is the tick-borne disease simply an issue for people living in New England, where it first appeared and is still prevalent.
The study analyzed 6 million blood tests administered by doctors checking for Lyme disease, The Washington Post reported.
The disease is still mainly prevalent in the Northeast, with Pennsylvania reporting the most cases last year -- 10,001 cases, effectively raising the state's positive results for Lyme disease by 78 percent since 2016.
For reference, the number of confirmed cases in the U.S. in 1995 was just over 10,000. There were a little over 25,000 just two decades later, in 2015.
Quest's study found that U.S. cases were still concentrated in six New England states ─ Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont ─ with those six, plus Pennsylvania, accounting for 60 percent of confirmed cases last year.
