What kills Coronavirus? As it has become an uncontrollable global disease and spreading rapidly, everyone is concerned about this question. World Health Organization (WHO) declared Coronavirus a global pandemic officially on March 11. And according to the CDC (Centers for Disease Control and Prevention, it is the first outbreak of an epidemic in 11 years. 

Association between Coronavirus and Sunlight

According to a lab experiment, high-temperature or humidity can reduce the transmission of Coronavirus and impacts its behavior. But not all the disease experts are convinced yet.

It makes sense to some extent that sunlight affects Coronavirus if we compare the spread pace of COVID-19 in different countries. The spread of this virus in the countries with less humid and colder climate is rapid than those that are warmer.

As the temperature is warming, there are possibilities of decreasing the spread of COVID-19.

A recent research paper stated:

“The number of patients and reported deaths in Southeast Asia is much less when compared to more temperate regions noted … The association between temperature in the cities affected with COVID-19 deserves special attention.”

It offers some hope that the coming days of summer may prove less hospitable for this virus. Yet experts warn that the change of climate will not eliminate it. As the behavior of all viruses is not always the same in certain climate conditions.

What Temperature Kills Coronavirus?

According to research,  SARS-CoV-2 can easily survive up to 72 hours on hard surfaces between the temperature of 21-23C and in relative of 40% of humidity. The indoor temperature excess of 30-32 degrees Celsius can reduce the life span of the virus. Furthermore, the virus survives in the body at 37 Celsius, but when the outdoor temperature is more than 40-50, Corona will not spread as rapidly. But how it behaves at different temperatures is under the to be tested yet.


How long will Coronavirus stay on surfaces?

Coronavirus, which is responsible for the disease of COVID-19, spreads not only by people to people interaction, but it remains alive on different surfaces for a specific period.

But the accurate figure depends upon the density of virus particles and the types of infected surfaces.

Pathologany experiments  within a controlled laboratory setting to test how long will Coronavirus last on surfaces of various kinds. They found that it will stay on plastic and steel as long as 72 hours. On cardboard, it stays for up to 24 hours and remains on copper for 4 hours.


There are too many opinions on the matter of this infectious disease. Some experts say that the weather will not significantly slow the spread of Coronavirus as it is not the seasonal disease. So unlike seasonal outbreak, which tends to reduce in the summer season, SARS-CoV won’t behave in the same manner. Unusually warm weather of high temperatures can slow the spread of Coronavirus but won’t completely stop it.
