Coronavirus can last hours in air, on surfaces

According to a new study from the National Institutes of Health, CDC, UCLA and Princeton University scientists, the virus that causes coronavirus disease 2019 (COVID-19) is stable for several hours to days in aerosols and on surfaces.

The study found that the virus was found up to 3 hours as an aerosol, up to 4 hours on copper, up to 24 hours on cardboard, and up to 3 days on plastic and stainless steel. This suggests that people infected with the virus may be spreading it without recognizing, or prior to recognizing symptoms.

The NIH study attempted to mimic virus being deposited from an infected person onto everyday surfaces in a household or hospital setting, such as through coughing or touching objects. The scientists then investigated how long the virus remained infectious on these surfaces.

 

This affirms the following guidelines to prevent the spread of the SARS-CoV-2 virus:

-Avoid close contact with people who are sick.

-Avoid touching your eyes, nose, and mouth.

-Stay home when you are sick.

-Cover your cough or sneeze with a tissue, then throw the tissue in the trash.

-Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.
