Even though the summer may be half over, the season for Lyme disease, West Nile virus and Eastern Equine Encephalitis is in full swing.

Dr. Alan Carter, medical director at Mercy Primary Care Center, said cases of Lyme disease have been diagnosed at Mercy Hospital offices in Portland and Westbrook.

“Deer ticks, which harbor the organism that causes Lyme disease, are prevalent in southern coastal Maine,” said Carter. “When walking in wooded areas or tall grass, wear shoes and clothing, and use insect repellent. People should inspect themselves and their children for ticks, which can attach to any part of the body, including the scalp.”

Dr. Carter notes that when treated early, people with Lyme disease can fully recover. According to Carter, early symptoms of Lyme disease include a red rash at the site of the tick bite up to 30 days after the bite. Other symptoms may include fever, joint and/or muscle pains.

Two other insect borne diseases also are of concern. Mosquitoes carry West Nile virus and Eastern Equine Encephalitis. Carter notes that even though no human cases of these diseases have been reported, people should minimize exposure to mosquitoes. “This includes reducing standing water as much as possible around your house. Even small amounts in buckets or gutters can be a welcome breeding ground,” says Carter. “During peak mosquito hours of dawn and dusk, people should consider wearing long sleeves and pants, and use insect repellent.”

Symptoms of West Nile and Eastern Equine Encephalitis include fever, vomiting, headaches and even symptoms that resemble stroke. People who have these symptoms should immediately contact their doctor.

“These simple, yet effective, precautions could make a big difference in one’s health,” said Carter.
