UNDATED — Pennsylvania officials are warning residents that there is now a danger of Lyme disease in every county in the commonwealth. Department of Environmental Protection researchers say that blacklegged deer ticks have now been observed in all 67 Pennsylvania counties, the first time that has happened.
Officials say parents should check children for ticks and showering within two hours of outdoor exposure may also help prevent transmission. Pennsylvania has reported the most cases of Lyme disease in the nation for the past five years. (Jennifer Wakeman)
