Coronavirus survives three days on plastic and stainless steel

Three hours in the air. Three days on plastic and stainless steel. That’s how long the corona virus survives. This is shown by the results of a new study by scientists from the National Institute of Allergy and Infectious Diseases in the USA. The center is responsible for research on infectious diseases, autoimmune diseases and allergies.

Using a sprayer, the researchers spread droplets of virus released by an infected person when they cough or sneeze across different surfaces.

–

The tests show that the virus remains viable in the air for at least three hours. The pathogen could still be detected on plastic and stainless steel after three days. The virus was no longer viable on cardboard after 24 hours. On copper, it took four hours for the virus to become inactive.

Half-life for plastic is just under 7 hours

The research team also found that it takes 66 minutes for half of the virus particles to stop functioning if they are in a droplet in the air. After another hour, 25 percent of the particles are still viable. At the end of the third hour, the amount drops to 12.5 percent.

It looks like this on stainless steel: After 5 hours and 38 minutes, half of the particles are still active.

–

The half-life for plastic is 6 hours 49 minutes. It is three and a half hours on cardboard. The shortest survival time was on copper, where half of the virus was inactivated within 46 minutes. (one)

The corona virus currently keeps the world in suspense. Many countries take measures such as closing schools or borders and restricting public events to prevent them from spreading. The virus is also rampant in Switzerland. All current information and figures on the subject are available in the Coronavirus ticker.
