When an infected person touches a surface, like a door handle, there’s a risk they leave viruses stuck there that can live on for two to three days.
The question has arisen about how long coronavirus can survive on the surfaces and how one can disinfect that surface. Coronavirus has been a major problem worldwide. People are worried about the places they are visiting, about the equipment or things they are using in their day to day life such as kitchen counters, toilet seats and many more.
But how long can the new coronavirus linger on surfaces, anyway? The short answer is, we don’t know. A new analysis found that the virus can remain viable in the air for up to 3 hours, on copper for up to 4 hours, on cardboard up to 24 hours and on plastic and stainless steel up to 72 hours
If new coronavirus resembles other human coronaviruses, such as its “cousins” that cause SARS and MERS, it can stay on surfaces — such as metal, glass or plastic — for as long as nine days. But there are some of them which cannot remain active in temperatures higher than 86 degrees.
But some of them don’t remain active for as long at temperatures higher than 86 degrees Fahrenheit (30 degrees Celsius). It is also found that these coronaviruses can be effectively wiped away by household disinfectants.
It’s possible that a person can be infected with the virus by touching a contaminated surface or object, “then touching their own mouth, nose, or possibly their eyes. People are recommended to not touch their faces with their hands.
The virus is most likely to spread from person to person through close contact and respiratory droplets from coughs and sneezes that can land on a nearby person’s mouth or nose.
The new study supports guidance from public health professionals to slow the spread of COVID-19:
- Avoid close contact with people who are sick.
- Avoid touching your eyes, nose, and mouth.
- Stay home when you are sick.
- Cover coughs or sneezes with a tissue, and dispose of the tissue in the trash.
- Clean and disinfect frequently touched objects and surfaces using a household cleaning spray or wipe.
