The coronavirus dies quickly when exposed to the ultraviolet rays of the sun. Like other enveloped viruses, SARS-CoV-2 survives longest at room temperature or lower and at low relative humidity (<50%).

Will the COVID-19 virus live on clothes for a long time?

Research has shown that COVID-19 does not survive long on clothing compared to hard surfaces, and exposing the virus to heat may shorten its lifespan. A study published in The Verge found that at room temperature, COVID-19 was detected on fabrics for up to two days, compared to seven days on plastics and metals.

Will COVID-19 damage organs?

UCLA researchers are the first to create a version of COVID-19 in mice to show how the disease damages organs other than the lungs. Using their model, the scientists found that the SARS-CoV-2 virus can turn off energy production in cells in the heart, kidney, spleen and other organs.

Who is most at risk of becoming severely ill with COVID-19?

COVID-19 can cause mild to severe illness. This could result in someone being admitted to a hospital or even an intensive care unit. It can even lead to death.
