How long do germs and bacteria live?

On suitable indoor surfaces, cold germs can linger for days, but fortunately they rarely remain infectious for more than 24 hours. Cold viruses can also thrive on the skin, but their survival time there is generally measured in mere minutes or hours.

How long do germs live on dry surfaces?

“It’s estimated viruses can live anywhere from one to seven days on non-porous surfaces, but they quickly lose their ability to cause infection.” Dr. Rosa groups common household germs into viruses or bacteria and lists how long these invisible threats can stick around.

How long do germs stay on hands?

In the cases of both flu and cold-causing viruses, infectious particles on our hands are usually gone after 20 minutes.

Does vinegar sanitize laundry?
