See how long COVID-19 lives on steel, cardboard, plastic, and airborne – Why it is easily transmitted – See pictures
This is how long coronavirus lives on steel, cardboard, plastic — and airborne, says a New England Journal of Medicine study
The scientists found that SARS-CoV-2, the virus that causes COVID-19, was detectable in the air for up to three hours, up to four hours on copper, up to 24 hours on cardboard, and up to 2 to 3 days on plastic and stainless steel.
The results of the study provide additional insight into the stability of the new SARS-CoV-2, or severe acute respiratory syndrome coronavirus 2, and suggest that people may acquire the virus through the air and after touching contaminated objects, according to the authors.
How long the virus remains “stable” — the term used by the researchers — would likely depend on the humidity and temperature of the room, and other variables including air-conditioning, open windows, and the general air quality, experts say, and advice using such results as a guide.
One theory: Emerging evidence suggests that people infected with COVID-19 might be spreading the virus without recognizing, or prior to recognizing the symptoms. This would make disease-control measures that were effective against SARS-CoV-1 “less effective against its successor.”
- Avoiding close contact with people who are sick.
- Avoiding touching your eyes, nose, and mouth.
- Staying home when you are sick.
- Covering your cough or sneeze with a tissue, then throwing the tissue in the trash.
- Cleaning and disinfecting frequently-touched objects and surfaces with a cleaning spray or wipe.
COVID-19, the disease caused by SARS-CoV-2, the official name for this new coronavirus, had infected at least 53,660 people in the U.S. by Tuesday evening and killed at least 703, according to data aggregated by Johns Hopkins University. Worldwide, there were 417,582 confirmed cases and 18,612 deaths; 107,247 people have recovered.
