Sun exposure does not kill the coronavirus
If Your Time is short
There is no evidence that sun exposure kills the 2019 coronavirus. UNICEF has debunked a post that claims the organization said sunlight is effective against the virus.
There is evidence that viruses don’t like heat. President Trump has said coronavirus infections could slow with warmer weather, but some experts doubt that prediction.
A few of the best ways to prevent the coronavirus are to wash your hands with soap and water, avoid touching your face and disinfect surfaces in your home daily.
According to a recent Facebook hoax, all you need to cure the 2019 coronavirus is a little sunshine.
An image published March 9 claims to show a list of recommendations from UNICEF for preventing and treating the virus. Among them include "drinking hot water and sun exposure" and "stay away from ice cream and eating cold."
"Corona virus when it falls on the fabric remains 9 hours, so ‘washing clothes’ or ‘being exposed to the sun for two hours’ meets the purpose of killing it," reads the handout in the photo.
The post was flagged as part of Facebook’s efforts to combat false news and misinformation on its News Feed. (Read more about our partnership with Facebook.)
PolitiFact has fact-checked a variety of false cures and ways to prevent coronavirus infection. We’re adding this one to the list.
There is no evidence that sun exposure kills the coronavirus, known officially as COVID-19. UNICEF has debunked the claim. (UNICEF is a humanitarian organization, not a public health institution.)
In a statement published March 6, Charlotte Petri Gornitzka, UNICEF’s deputy executive director for partnerships, addressed some misinformation about the coronavirus, including the fake handout.
"A recent erroneous online message circulating in several languages around the world and purporting to be a UNICEF communication appears to indicate, among other things, that avoiding ice cream and other cold foods can help prevent the onset of the disease," she wrote. "This is, of course, wholly untrue. To the creators of such falsehoods, we offer a simple message: STOP."
There is ample evidence that viruses, including human coronaviruses, don’t like heat. Influenza, for example, thrives in dry, cold weather, which is one reason the flu season typically spans from fall to spring. Viruses that cause the common cold also like colder weather.

In February, President Donald Trump said the coronavirus will "go away in April" due to the arrival of warmer weather. But some health experts have cast doubt on that prediction, saying there’s no guarantee the virus will cease infecting people in the summer. And if it does, that doesn’t mean the virus will be gone for good.
As of March 10, more than 113,000 people in 109 countries had been infected with the coronavirus. In the United States, there have been 938 confirmed cases and 31 deaths.
According to the Centers for Disease Control and Prevention, the best ways to prevent the 2019 coronavirus are to wash your hands with soap and water, avoid touching your face, avoid close contact with sick people, cover your coughs and sneezes, and disinfect surfaces in your home daily. As of now, there is no specific treatment for the virus.
The Facebook post is inaccurate. We rate it False.
