Specialists from several US research centers have received new data on coronavirus, the spread of which has recently reached the stage of a global pandemic.
According to the study, the pathogen can survive in the air for several hours, and on some surfaces for two to three days.
During the experiments, researchers used a nebulizer – a device for inhalation. With its help, they simulated the ingress of a virus into the air with drops of aerosol (for example, when coughing or sneezing an infected person).
It turned out that the pathogen remains viable in the air even after three hours. On a copper surface, it survives for four hours.
The virus that has fallen onto the cardboard remains viable for 24 hours. And on plastic and stainless steel, it can survive up to two to three days.
This means that a person can become infected if he breathes in aerosol droplets containing the virus, or touches a contaminated surface and then touches his face with his hand (the pathogen enters the body through the mucous membranes of the mouth, nose and eyes).
In this regard, experts once again recall the importance of hygiene and disinfection.
It is also noted that similar results were obtained in tests conducted with another coronavirus – the one that caused an outbreak of SARS in 2003.
A new study has not yet been reviewed. A preprint of the scientific article you can read at Medrxiv.
Recently, Chinese experts analyzed the case of the spread of the pathogen on the bus and came to the conclusion that it can remain in the air for at least 30 minutes and travel up to 4.5 meters.
Some researches think, that in the future, coronavirus infection may become seasonal, like flu.
