Bad Tick Season May Lead to More Lyme Disease
By: Dr. George Cavanagh
Following a mild winter, Maryland’s tick population was expected to explode this summer. This could lead to a record number of Lyme disease infections in 2019.
Warmer winters allow black-legged ticks, which are the chief carriers of Lyme disease, to remain active longer and spread the illness into new regions of the country. Maryland gets about 1,300 cases of Lyme disease each year, but that number may climb this year.
Lyme Disease Symptoms
Bites from infected ticks often leave a bull’s-eye-shaped rash: a red spot surrounded by white and red circles. Symptoms of Lyme disease include flu-like symptoms (fever, chills, fatigue, body aches and headache), facial paralysis and swollen knees. If left untreated, Lyme can progress to more serious issues like memory problems, heart rhythm irregularities and chronic arthritis.
Not every tick bite leads to Lyme disease, especially if you get them off soon, but if you are bitten by a black-legged tick, see your doctor for antibiotics to treat the illness.
Tips for Prevention
- Avoid areas with high grass, brush and leaf clutter.
- Wear light-colored clothing, long sleeves and closed-toe shoes when hiking. Tuck your pants into your socks, too.
- Use insect repellent containing permethrin to treat your clothes and shoes. Use repellent with DEET, picaridin or IR3535 on your skin
- If you’ve been in a tick-prone area, thoroughly check your body for ticks and shower as soon as possible once indoors.
- Put your clothes in the dryer on high heat for at least 10 minutes to kill any ticks on them.
- If you find a tick, remove it with tweezers immediately.
- Call your doctor if you experience any of the symptoms listed above after removing a tick.
- Check dogs and cats for ticks frequently, and ask your veterinarian about tick preventives.
As a general rule, if you spend time outdoors in an area prone to ticks, assume you’ve picked one up. Do a thorough check when you’re back indoors and remove any ticks immediately.
