High awareness in the region comes due to the terrible side effects that come with Lyme and to other extents the similarly caused erlichiosis, anaplasmosis and babesiosis.
Older maps by the CDC pinpointed one spot per occurrence, but the latest iteration shows the risk level of acquiring the disease, which causes arthritis and neurological problems, by county, reports National Geographic. It is spread by the bite of infected deer ticks.
The maps shows increases in cases. In 1993, 69 counties in the country qualified as high-risk areas. In 2012 there were 260, which is a 400 percent increase.
