Coronavirus Survival Rates on Surfaces & How You Can Protect You and Your Family



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.


Coronavirus: What you Need to Know

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, jewellery, silverware 5 days


Wood Examples: furniture, decking 4 days


Control Spread of Coronavirus

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:
