How Long Corona Virus Can Survive on Different Surfaces?

When a COVID19 infected person coughs for a single time, this action can spread up to 3,000 droplets of corona virus (SARS-CoV-2) in the surrounding air. It is estimated that the airborne droplets can carry active and possibly infectious Corona Virus for about three hours. These Corona Virus droplets can be spread from one person to another if those people stay in close contact measuring less than two meters.

However, if an individual comes in contact with surfaces upon which the Corona Virus droplets have landed and haven’t been disinfected yet, then that person may get infected by COVID19. Furthermore, the droplets of corona virus (SARS-CoV-2) can also spread in the air through the actions of exhaling and speaking.

Can Temperature and Humidity Influence the Corona Virus?

The survival period of Corona Virus SARS-CoV-2 can definitely be affected by factors like temperature and humidity. According to the Centers for Disease Control and Prevention (CDC), the new corona virus can survive only for a shorter period at higher temperatures and humidity levels. It is found that the new corona virus (SARS-CoV-2) remains highly active at 4°C Celsius (about 39°F). On the other hand, it becomes rapidly inactivated at 70°C (158°F).
