Excerpt from: https://en.wikipedia.org/wiki/Lyme_disease
Lyme disease is the most common disease spread by ticks in the Northern Hemisphere.
It is estimated to affect 300,000 people a year in the United States and 65,000 people a year in Europe.
Infections are most common in the spring and early summer.
Lyme disease was diagnosed as a separate condition for the first time in 1975 in Old Lyme, Connecticut. It was originally mistaken for juvenile rheumatoid arthritis. The bacterium involved was first described in 1981 by Willy Burgdorfer
