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.
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.
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.
