How Long Does the Coronavirus Live on Surfaces?
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 金属
Examples: doorknobs, jewelry, silverware
5 days
Wood 木材
Examples: furniture, decking
4 days

Paper 紙
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 食べ物一般
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 水
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.
その他
Coronaviruses can live on a variety of other surfaces, like fabrics and countertops. One study tested the shoe soles of medical staff in a Chinese hospital intensive care unit (ICU) and found that half were positive for nucleic acids from the virus. But it’s not clear whether these pieces of the virus cause infection. The hospital’s general ward, which had people with milder cases, was less contaminated than the ICU.
