What You Need to Know about Tick and Mosquito-Borne Illness

Cases of illness related to ticks, mosquitoes, and fleas have increased dramatically in recent years, leading to widespread concern.

As a parent myself, I know I have to think more about protecting my kids from bug bites than my parents did for me. First of all, our environment is more hospitable to these bugs. Our deer population has exploded in recent years, which gives deer ticks a place to live and breed. Funding for mosquito control measures has decreased, so it’s harder to control the mosquito population.

While the CDC report didn’t address the issue of climate change, areas that were previously cooler have warmed, allowing the tick and mosquito populations to thrive.

Not only can tick and mosquito bites make a child uncomfortable, diseases like Lyme, B. miyamotoi, West Nile, Eastern Equine Encephalitis (more commonly known as EEE), and others can present additional health risks.

The headlines are alarming. But your family doesn’t have to stay indoors this summer to stay healthy.

Here are a few steps to take:

Apply bug repellent, especially at dawn and dusk

As your family transitions to your summer schedule, make applying bug repellent part of your morning routine. This is especially important if a member of the family is doing activities like a nature walk, forest hike, or will be picnicking in grass. Reapply the repellent for those evening athletic games and practices to keep mosquitoes at bay.

Know your ticks

There are two common kinds of ticks in our region: Deer ticks and dog ticks. Most tick-borne illnesses in New England are transmitted by the smaller deer ticks. Check out this printable reference guide from the Massachusetts Department of Public Health on how to identify a tick.

Remove ticks when they bite

Whether it’s a deer tick or dog tick, remove an embedded tick as soon as you find it. Using tweezers, grasp as much of the tick as you can as close to the skin as possible, pulling firmly and steadily to remove. If you don’t remove the entire tick, don’t worry. The parts that remain attached get reabsorbed and won’t cause harm.

Monitor the area

Once the tick is removed, observe area periodically for the next several weeks. More than half of patients with Lyme disease see an expanding rash after a bite. If you notice a rash that’s growing, call your doctor.

Keep an eye out for summer fevers

In the winter months, an illness accompanied by fever often means a patient has the flu. But illnesses transmitted by bugs can also cause a fever, so it’s possible your family member has a bug-borne illness. It’s best to call your doctor, especially if you’ve had mosquito or tick bites.

A quick note on insurance and tick-borne disease testing

If you or a family member have symptoms of Lyme disease, call your primary care provider to get checked out. It’s also a good idea to call your health insurance company to understand your policy’s coverage of blood testing for tick borne disease. You’ll find the customer service number on the back of your insurance card.

Don’t let fear of bug-borne illness keep your family from enjoying the summer months. By taking some precautions, you can safely enjoy all summer in New England has to offer.
