Coronavirus Stays Stable on The Surface. How Long?

Coronavirus' new form COVID-19 is stable as the SARS virus is.

Coronavirus Stays Stable on The Surface. How Long?


Coronavirus is stable for many hours and even days as a new study suggests. It is stable in aerosols and on surfaces. The scientists found out that the new SARS-CoV-2 can stay calm in aerosols for 3 hours, on copper for 4 hours, on cardboard up to 24 hours, and on stainless steel and plastics it can remain stable for even two or three days!  

The new study is an effort by the National Institutes of Health, CDC, UCLA and Princeton University scientists in The New England Journal of Medicine.

This new study increases our knowledge of the stability of the SARS-CoV-2 that is responsible for the COVID-19 disease. The research team hints that people may come in contact with the virus from the air and the touching contaminated objects. After finding out the stability qualities of the virus, the team shared its data quickly with their colleagues worldwide by using a preprint server. Their effort has been shared several times during the past two weeks. 

SARS-CoV-1 and SARS-CoV-2 cause SARS. Scientists from the National Institute of Allergy and Infectious Diseases' Montana facility at Rocky Mountain Laboratories made a comparison between the two. SARS-CoV-1 emerged from China back in 2002 and 2003 and infected more than 8,000 people. To fight this virus, experts used case isolation measures, and contact tracing and no new cases appeared since 2004. SARS-CoV-2 is closely related to SARS-CoV-1 in the case of their stability. But why the COVID-19 infected people are becoming large in number is still a mystery.

In households and hospitals with affected people, people knowingly or unknowingly deposit the virus on surfaces through touching objects or coughing. The NIH experts focused on the virus to find out how long it is infectious while staying on surfaces. 


What are the additional observations?

It is a question that if both of the virus forms are similarly stable, then why SARS-CoV-2 is so deadly? The main reason behind that is people can not recognize the virus as the symptoms come late in appearance. For this, the preventative measure against its successor SARS-CoV-1 seems less fruitful.

SARS-CoV-2 infects secondary cases in community settings, not in healthcare settings, and it completely contrasts the appearance of SARS-CoV-1. SARS-CoV-2 can spread in healthcare settings as they are vulnerable to this virus. Besides, its stability on surfaces and in aerosols increases its transmission within the healthcare settings.

To stay away from getting infected by the virus, we have to take precaution measures similar to the steps we take for influenza and other respiratory viruses. They are-


Closing contact with infected people

Stop touching the mouth, nose, and eyes without any reason.

If you are sick, stay at home.

Use a tissue to cover your face while coughing and sneezing and throw it to the trash later.

Use cleaning spray and wipe to clean surfaces and objects that you touch frequently.
