The Centers for Disease Control and Prevention says the number of tick-borne diseases like Lyme disease is increasing at a record pace.

Around 75% of people who contract Lyme disease develop a rash at the site of the tick bite, according to the CDC. The rash often looks like a bullseye and usually appears three to 30 days after the bite. It can expand up to 12 inches wide and may feel warm to the touch but typically doesn't itch or hurt.

However, many Lyme disease symptoms are similar to COVID-19 symptoms, including fatigue, pain, fever and nausea. News 12's Elizabeth Hashagen was joined by Dr. Andrew Handel, a pediatric infectious disease expert, who says climate change is a big factor in why there are more ticks. He also explained what symptoms to watch out for.

There are ways to try and prevent tick bites. Dr. Handal says using bug spray that contains DEET and checking for ticks if you have been outside is helpful.
