Lyme Disease is a bacteria transmitted to humans by the bite of an infected Blacklegged tick (or deer tick). Symptoms may include headache, fever, and the characteristic "bulls-eye" skin rash (erythema migrans). If not treated, the infection can spread to joints, heart and nervous system. Lyme disease is diagnosed based on symptoms, physical findings (like the rash) and the possibility of exposure to ticks.
According to the Centers for Disease Control and Prevention (CDC), in 2015, 95% of confirmed Lyme disease cases were reported from only 14 states; Maryland was one of those states!
