Lyme Disease continues to be very common in the Midcoast Maine area but we're seeing anaplasmosis and other tick-borne diseases more frequently. Knowing how to prevent tick bites and considering tick-borne diseases when symptoms occur continues to be important. The CDC has useful information on its web site and even an iPhone, iPad and Android app for this.
While it's great that winter has finally ended and flu season is winding down, it's already time to take steps to prevent Maine tickborne diseases such as Lyme Disease, anaplasmosis, ehrlichiosis and others. The deer (Blacklegged), Dog and Lone Star ticks are already out there and the spring nymph form of the deer tick is quite small and easily missed.
Some simple precautions when outside in the yard or the woods can reduce your risk. Check yourself, your children and pets for ticks daily. Lyme Disease is not transmitted immediately so removing a deer tick within 24 hours greatly reduces that risk. In some cases, a dose of antibiotic may be considered to prevent Lyme Disease if a deer tick has been attached for 24 hours or more. Check with your physician promptly as this should be done within 72 hours of removing the tick to be effective.
Most people know about DEET for keeping ticks, black flies and mosquitoes from biting exposed skin but fewer are familiar with permethrin for treating clothing. You can buy clothing pre-treated with permethrin or treat your own clothing (NOT skin) following the manufacturer's instructions. This usually remains effective through several washings. Here in Rockport, Maine Sport Outfitters has permethrin clothing spray in stock in the camping section but most of the other local outdoor sports stores also had it when I've checked in the past.
Patients often bring in ticks that they've removed. While this can help us decide if it's a deer tick, testing the tick for Lyme Disease is not usually helpful.
Finally, Lyme Disease and the other tickborne diseases in Maine can present with a wide variety of symptoms. You should check with your physician if you or a family member have symptoms during tick season such as rash, fever, a flu like illness, new joint problems, severe headache or neurologic changes, enlarged lymph nodes or other unexplained symptoms.
