Researchers said the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), known as Covid-19, has different life span depending on the type of surfaces - airborne droplets, hard shiny surfaces and porous objects. The virus rapidly degrades during this time, reported weforum.org.

Airborne droplets - 3 hours

Researchers found SARS-CoV-2 remains infectious in airborne droplets for at least three hours. However, it is yet not known if infected humans produce enough virus in a cough to infect another person.

Up to 24 hours on porous surfaces

Researchers found that after 24 hours, there were no viable traces of the virus on cardboard. Hence, fibrous and absorbent surfaces such as cardboard, paper, fabric and hessian, the becomes inactive more quickly.

Hard, shiny surfaces - up to 72 hours

The virus survives on things like plastic, glass, counter tops, stainless steel for up to 72 hours. So if the virus is expelled in droplets which land on to these surfaces, they can contaminate them. It is best advised to wash hands after touching objects like play equipment, door, public transport handles and phones.

Wash your hands to protect against Covid-19

Finally, researchers advised the best way to keep virus at bay is wash hands properly and much more often than usual. Between hand-washing, avoid constantly touching the mucous membranes that lead to your airways. Basically, try not to rub your eyes, pick your nose, or touch your lips and mouth.
