Mary Beth Thakar is so passionate about getting the word out about Lyme disease, she wrote a song about it. Well, she re-wrote the lyrics to the tune “There Was An Old Lady Who Swallowed a Fly.”

The first verse goes like this: I know an old lady who was bit by a tick...or some kind of bug...maybe a tick. She might get sick.

Thakar was just diagnosed with Lyme this year, but she thinks she might have become infected about five years ago.

In 2013, the Centers for Disease Control and Prevention recorded 27,203 cases of Lyme disease nationwide, 4,981 of which were in Pennsylvania. And, for the last five years, Pennsylvania has reported more cases of Lyme disease than any other state.

As temperatures rise and people begin to spend more time outdoors, U.S. Sen. Bob Casey (D-Pennsylvania) is calling for an increase in federal surveillance.

Put on a long sleeve shirt and load up on some pest repellent, because tick season in Pennsylvania is expected to get progressively worse year after year.

According to a Centers for Disease Control and Prevention report, Pennsylvania leads the nation in the number of Lyme disease cases, and Penn State Urban Entomologist Steve Jacobs said that’s because of an increasing tick population.

“The only thing I can say for certain is that, across Pennsylvania for the last 25 years, we’ve been trending having more ticks in more places,” he said. “That will continue.”

Ticks are about as well-loved as invasive dental surgery, so it’s likely a relief to many that 2013 is forecast to be an average or below average tick year, according to the Carey Institute of Ecosystem Studies.

Despite that prediction, it’s still important to be wary of ticks, said Ed Rajotte, a professor of entomology at Penn State.
