Can viruses live in the freezer?

Although freezing temperatures will prevent Listeria bacteria from growing, they don't kill the bacteria, Chapman said. The microbes survive in the freezer, he said. In addition, Listeria are among the few bacteria that can actually multiply at refrigerator temperatures, according to the CDC.

Correspondingly, can the flu virus survive in the cold?

Like cold viruses, infectious flu viruses survive for much shorter periods on the hands. After five minutes the amount of flu virus on hands falls to low levels. Flu viruses can also survive as droplets in the air for several hours; low temperatures increase their survival in the air.

Do viruses thrive in the cold?

Scientists found that in cold temperatures, the flu virus forms a hard coating that acts like an envelope, helping the virus spread through cold air and then melting inside people to do its dirty work. In warmer temperatures, that coating doesn't form. So it's harder for the influenza virus to spread through warm air.

Can flu germs survive freezing temperatures?

Infectious flu viruses can survive on tissues for only 15 minutes. Like cold viruses, infectious flu viruses survive for much shorter periods on the hands. Flu viruses can also survive as droplets in the air for several hours; low temperatures increase their survival in the air.
