How Long Does the Coronavirus Live on Surfaces? – WebMD

Over the 10 years I have been producing this blog I have found WebMD to be a superb source of information. I think they continue to excel in this latest on the coronavirus. Understanding how the virus is transmitted and long it lives on surfaces is key to protecting ourselves from it.

The coronavirus that causes COVID-19 mainly spreads from person to person. When someone who is infected coughs or sneezes, they send droplets containing the virus into the air. A healthy person can then breathe in those droplets. You can also catch the virus if you touch a surface or object that has the virus on it and then touch your mouth, nose, or eyes.

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.

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.
