How long can influenza virus survive on surfaces

“Flu viruses can survive on hard surfaces (like bus poles) and infect another person for 24 to 48 hours,” she says. “Cold viruses don’t survive as long—usually a few hours. But there is evidence that they can survive and be passed on for up to 24 hours.”

How long can a flu virus survive?

How long does the flu virus live on hard surfaces?

The influenza virus that causes the flu tends to live longest on hard surfaces, says Kelly Reynolds, MSPH, PhD, a microbiologist at the University of Arizona’s Zuckerman College of Public Health. “Flu viruses survive for 24 to 48 hours on stainless steel and plastic,” Reynolds says.

How long do viruses last on common surfaces?

Here’s how long the virus typically lasts on common surfaces, but it can change depending on sanitation efforts, sunlight and temperature: 1 Glass – 5 days. 2 Wood – 4 days. 3 Plastic & stainless-steel – 3 days. 4 Cardboard – 24 hours. 5 Copper surfaces – 4 hours. More

How long do virus droplets stay infectious?

Cold and flu virus-laden droplets may remain infectious for several hours, depending on where they fall. Viruses generally remain active longer on stainless steel, plastic and similar hard surfaces than on fabric and other soft surfaces.

How long can a virus survive in a cold?

“Flu viruses can survive on hard surfaces (like bus poles) and infect another person for 24 to 48 hours,” she says. “Cold viruses don’t survive as long—usually a few hours.

How long do flu viruses last on your hands?

NHS officials say flu viruses don’t last long on hands, falling to low levels within about five minutes. But within those few moments, it is very easy to transfer the virus to eyes, mouths and noses, or leave it on surfaces where the virus will survive.

How long do viruses stay active?

Viruses generally remain active longer on stainless steel, plastic and similar hard surfaces than on fabric and other soft surfaces. Other factors, such as the amount of virus deposited on a surface and the temperature and humidity of the environment, also determine how long cold and flu viruses stay active outside the body.

How long can a virus live on a porous surface?

Most flu viruses can live one to two days on nonporous surfaces, and 8 to 12 hours on porous ones.
