How long COVID-19 can survive at room temperature is related to the prevention effect

As we all know, COVID-19 likes cold and fears heat. For COVID-19, the lower the temperature, the more favorable it is, and the higher the temperature, the more unfavorable it is. How long can COVID-19 survive at room temperature? Let's take a look together below!

How long can COVID-19 survive at room temperature

3 hours in aerosol; It can survive on the surfaces of four contact materials, namely copper (3.4 hours), cardboard (8.45 hours), stainless steel (13.1 hours), and plastic (15.9 hours).

Survival time is related to temperature and humidity, and viruses do not like high temperature and high humidity environments. Studies have shown that viruses can survive for several hours on smooth surfaces, and for several days if the temperature and humidity are appropriate. For example, in an environment of 20 ℃ and 40% humidity, some studies have shown that novel coronavirus can survive up to five days.

Generally speaking, as long as the temperature is below zero, such as -1 ℃ to -10 ℃, viruses like COVID-19 can survive for weeks to months. In the experiment, at 4° C and -20 ° C; At low temperature of C, COVID-19 is still infectious after 3 weeks.

How long can COVID-19 survive at room temperature

Since the COVID-19 broke out, China has repeatedly found COVID-19 on imported cold chain goods, which is a very big risk hazard. It is reported that COVID-19 can survive for 3 weeks under cold chain conditions, so cold chain goods may be imported across the border as a carrier of COVID-19. For this reason, China's customs is very strict in the detection of cold chain goods, so epidemic related cold chain food will be sealed or destroyed.

So, please wash your hands well. This is especially important to avoid the possibility of COVID-19 in the objects you touch!

Mode of transmission of COVID-19

The virus is mainly transmitted through droplets or contact. The droplets usually cough and sneeze. Its transmission distance in the air is limited, generally one or two meters. It subsides quickly after coming out of the human body.

So there will be no floating in the air, that is, there will be no COVID-19 in the air.

The above is about how long COVID-19 can survive at room temperature. I hope it can help you.
