One particularly disturbing Lyme-related development is the nation’s first-ever park closure. Pleasure Beach in Connecticut, a curved slip of sand used by thousands of Bridgeport residents, was shuttered on July 1, along with a popular fishing pier, due to tick infestation. In two other potential harbingers, a longhorned tick in Connecticut was found this summer to carry the bug that causes human monocytic ehrlichiosis, a disease usually associated with the lone star tick.
