Overview of COVID-19's survival rate on different materials.

One of the key pieces of information to understand what all you can do from spreading and infecting yourself from COVID-19 is how the virus survives and how it interacts within our environment and actions.

We have aggregated some of the most common scenarios and materials to give some references to how the virus survives on these materials. Researchers are still learning about the virus and how it behaves when it is exposed to heat, cold, or sunlight and how it affects its lifespan.


Metal
Examples: doorknobs, jewelry, silverware
5 days

Wood
Examples: furniture, decking
4 days

Plastics
Examples: packaging like milk containers and detergent bottles, subway and bus seats, backpacks, elevator buttons
2 to 3 days

Stainless steel
Examples: refrigerators, pots and pans, sinks, some water bottles
2 to 3 days

Cardboard
Examples: shipping boxes
24 hours

Copper
Examples: pennies, teakettles, cookware
4 hours

Aluminum
Examples: soda cans, tinfoil, water bottles
2 to 8 hours

Glass
Examples: drinking glasses, measuring cups, mirrors, windows
Up to 5 days

Ceramics
Examples: dishes, pottery, mugs
5 days

Paper
The length of time varies. Some strains of coronavirus live for only a few minutes on paper, while others live for up to 5 days.

Food
Coronavirus doesn't seem to spread through exposure to food. Still, it's a good idea to wash fruits and vegetables under running water before you eat them. Scrub them with a brush or your hands to remove any germs that might be on their surface. Wash your hands after you visit the supermarket. If you have a weakened immune system, you might want to buy frozen or canned produce.

Water
Coronavirus hasn't been found in drinking water. If it does get into the water supply, your local water treatment plant filters and disinfects the water, which should kill any germs.

Coronaviruses can live on a variety of other surfaces, like fabrics and countertops.

What You Can Do
To reduce your chance of catching or spreading coronavirus, clean and disinfect all surfaces and objects in your home and office every day. This includes:

Countertops
Tables
Doorknobs
Bathroom fixtures
Phones
Keyboards
Remote controls
Toilets


Use a household cleaning spray or wipe. If the surfaces are dirty, clean them first with soap and water and then disinfect them.

Keep surfaces clean, even if everyone in your house is healthy. People who are infected may not show symptoms, but they can still shed the virus onto surfaces.

After you visit the drugstore or supermarket, or bring in takeout food or packages, wash your hands for at least 20 seconds with soap and warm water. Do the same thing after you pick up a delivered newspaper.
