How Long Does Coronavirus Live on Surfaces

This was the investigation that launched the USA-eVote section on the Coronavirus. I was asked to print a simple list of the life expectancy of the coronavirus on various surfaces. I was rather shocked at the information I had to weed through before finding one site with a simple list of surfaces and the life expectancy of a virus on that surface. There was of course the general list of fake new sites. And there were some reliable websites. Some of which had information you had to possess a PhD to understand. Finally I found one website with the information I was looking for.

How long the coronavirus can survive on surfaces

The researchers compared the new coronavirus’ life span on surfaces with that of the SARS coronavirus in a 70-degree Fahrenheit room at 40% relative humidity. They found that both coronaviruses lived the longest on stainless steel and polypropylene, a type of plastic used in everything from food-storage containers to toys. Both viruses lasted up to three days on plastic, and the new coronavirus lasted up to three days on steel.

I prefer this site not because it is the most reliable, but because it took some rather complicated information from one website and took the time to put into in everyday English and a graph the average person can understand.

Following is a list of other useful web pages with more details and as I like, the subject explained from different angles.

WHO is continuously monitoring and responding to this outbreak. This Q&A will be updated as more is known about COVID-19, how it spreads and how it is affecting people worldwide. For more information, check back regularly on WHO’s coronavirus pages.

“The good thing about COVID-19 is that it does not require any unique cleaning chemicals to disinfect hands and surfaces,” says Andrew Janowski, an infectious disease expert at Washington University School of Medicine and St. Louis Children’s Hospital. COVID-19 is the disease caused by the current coronavirus.

Good old-fashioned soap and water does the trick.

The virus was more stable on plastic and stainless steel than cardboard,” said Todd Green, Ph.D., a virologist and an associate professor in UAB’s Department of Microbiology. “Viable virus was detected for up to three days on plastic and stainless-steel surfaces. While on copper, no viable virus was measured after four hours or on cardboard after 24 hours.”

The coronavirus can live for hours to days on surfaces like countertops and doorknobs. How long it survives depends on the material the surface is made from.

Here’s a guide to how long coronaviruses — the family of viruses that includes the one that causes COVID-19 — can live on some of the surfaces you probably touch on a daily basis. Keep in mind that researchers still have a lot to learn about the new coronavirus that causes COVID-19. For example, they don’t know whether exposure to heat, cold, or sunlight affects how long it lives on surfaces.
