ROCHESTER, N.Y. (WHEC) — There is all sorts of false information being put out on social media about the coronavirus.

A few viewers asked us a good question: Could higher temperatures or UV light help kill COVID-19?


First, the World Health Organization says exposing yourself to the sun or high temperatures does not prevent the coronavirus. It says you can catch the virus no matter how sunny it is and when it's hot.

News10NBC’s Nikki Rudd also looked into the idea that UV light could kill the virus and found a group of doctors in Michigan is actually researching this.

The doctors found UVC light, which is the most damaging type of UV radiation, can be used to kill the virus on masks.

"We were able to show that we can keep the integrity of the mask, we can kill the virus and then the healthcare worker can reuse it," dermatologist Dr. Iltefat Hamzavi said.

However, this is not something you can do at home.

"You can't take a nail salon's UV lamp and use it in your house and expect to kill the virus,” Hamzavi said. “So there's a lot of photo-medicine that's behind this."

The best minds in photo-medicine are working on this right now. Researchers are sharing their findings and protocols so hospitals can start replicating it.

Rudd also received a few other questions: Can cold weather or snow kill coronavirus? What about drinking alcohol, a hot bath or hair dryers?

According to WHO, the answer to all those questions is no.
