Evidence collected for SARS-CoV-2 showed that viruses in droplet aerosols (a fine mist) had a half-life of just over an hour but some could survive for three hours or more. Infectious virus could be detected on copper surfaces for up to four hours, on cardboard for up to 24 hours, and on plastic and stainless steel for at least 72 hours.

HOW LONG COVID-19 SURVIVES ON THESE SURFACES: • When the virus is attached to airborne droplets like moisture from coughs and sneezes, fog, dust or medical gases, it can survive up to three hours. • On copper surfaceslike draw handles, virus can last up to four hours. • On cardboard boxes and mail, the virus lives for up to 24 hours.

In this process, they disrupt the cell’s life cycle and it is that cellular damage that results in disease. So instead of asking how long a virus can live outside the body, we can ask how long it remains infectious, that is, how long it retains its ability to invade a living cell and cause mischief. That ability depends on how long the extremely complex structure of a virus stays intact. And extremely complex it is.

At 40°C virus was inactivated much more quickly. Infectious SARS-CoV-2 was detectable for less than 16 hours for cotton cloth, up to 24 hours for glass, stainless steel, paper and polymer notes and 48 hours for vinyl. From our data, we can also conclude that the virus will survive even longer at colder temperatures (less than 20°C).

Some studies on other coronaviruses, including Sars and Mers, found they can survive on metal, glass and plastic for as long as nine days, unless they are properly disinfected. Some can even hang...

Flu viruses can survive in the air for several hours, especially at lower temperatures, and on hard surfaces they can survive and remain infectious for 24 hours.

Early research has demonstrated that the virus’s survival depends on the type of surface it lands on. The live virus can survive anywhere between a couple of hours to a couple of days. Here’s how long the virus typically lasts on common surfaces, but it can change depending on sanitation efforts, sunlight and temperature: Glass – 5 days.

Different viruses seem to have differing abilities to survive outside the body, however, and we are still learning about the new coronavirus. One study suggested it can survive for up to 72 hours...

The novel coronavirus, or SARS-CoV-2, is active in the body for at least 10 days after a person develops symptoms. In people with severe illness, it may last up to 20 days. In some people, low...

Viruses survive outside our bodies because of how they are built. Specifically, they are pieces of genetic material (RNA or DNA) contained in a special coating of proteins called capsids. Viruses cannot replicate unless absorbed by cells in our body. Once a virus is outside the body, its capsid starts to degrade, and the more degraded its capsid is, the less likely it is to survive.
