Department of Health: Lyme disease, COVID-19 share symptoms

Ronald Keister late last month started feeling muscle and joint aches and developed a low-grade fever, making him wonder if he somehow contracted COVID-19.
The Laurelton resident, worried that his wife who has health problems was in danger, called his doctor to ask if he should be tested for the novel coronavirus. He was told to wait two days to see if the fever would go up; in the meantime, he and his wife noticed a big red welt on his shoulder. Keister had Lyme disease.
“We have woods out back, and I’m out there all the time,” said Keister. “I’ve had ticks before, and had no problems. I never saw the tick on this one.”
The state Department of Health last month put out a media release reminding Pennsylvanians to take proper steps to prevent tick bites and recognize the symptoms of Lyme disease, as some symptoms of Lyme disease are similar to those of COVID-19. Ticks can carry Lyme disease, among other dangerous diseases, that can be severe if not treated properly. (See link for article)
