In 2018, the Pennsylvania Department of Environmental Protection received state funding that enabled the creation of a statewide active tick and tick-borne pathogen surveillance program. This program began monitoring all 67 counties within the Commonwealth for tick distribution, density, and associated pathogens, helping to contribute to a publicly available, nationwide tick surveillance data set. Today, Pennsylvania is one of just a few states in the nation with such a comprehensive surveillance and testing program. Shown here is active surveillance for ticks via cloth dragging in tick habitat. (Photo by Brooke Coder)
