Three cases of Lyme Disease have been confirmed in Washington County so far this summer. No new cases have been confirmed in the county since the third week of July. According to Lynn Fisher with Washington County Public Health, usually one to four cases of lyme disease are confirmed in the county each year. She reminds people to prevent getting the diease by checking for ticks every two to three hours when outside, wear pants and long sleeves and use an insect repellent containing DEET. Also, if a tick is found, remove it immediately by grabbing the tick as close to the skin as possible with tweezers and pull it straight out.
