Contrary to previous beliefs, a study published revealed new findings regarding the life of the new coronavirus, in the air and on surfaces.

The virus may live for hours outside the human body on different surfaces or even in the air for a longer period than previously thought, according to the study published on Tuesday.

The authors of this study, which is funded by the US government, found that the virus that caused a pandemic that caused panic in the world has a survival capacity in the open air compared to SARS (severe acute respiratory syndrome).

The researchers also used sprays to spread the virus in the air, and they discovered through this technique traces of the virus in the form of particles suspended in the air, which remained in the air for 3 hours.

Their experiments showed that the emerging coronavirus can be monitored for up to two to three days on plastic or stainless steel surfaces, and up to 24 hours on cardboard.

This could mean that the extent of the "Covid 19" epidemic, which is much greater than the SARS outbreak in 2002 and 2003, is linked to being transmitted more easily from an asymptomatic carrier to another person.

This study was published in the "New England Journal of Medicine" and conducted by scientists from the Centers for Disease Control and Prevention (CDC) and the University of California, Los Angeles and Princeton.

But this study was criticized, so experts believe that the use of sprays does not effectively simulate a patient's cough, and it also increases the risk of artificial airborne pollution.

The virus is transmitted mainly through small drops that patients take out when they cough or sneeze, in which case it is viable for only a few seconds.

The team responsible for the current study conducted similar tests on the SARS virus, and found that the two viruses are similar at this point.

This does not explain why Covid 19 has infected about 200,000 people with nearly 8,000 deaths, while SARS has infected 8,000 people and killed 800 patients.

The authors of the study say the differences between the two epidemics "may be caused by other factors such as high viral load in the upper respiratory tract" and the ability of patients without symptoms to transmit the emerging corona virus.
