Coronavirus can remain viable in the air for up to several hours, and on some surfaces for up to three days, reports March 17 New england medical journal with reference to a study by American scientists.

“The virus can remain viable and contagious in the form of suspended particles for several hours, and on the surfaces for up to several days,” the publication said.

During the study, scientists sprayed aerosols with SARS-CoV-2 in the air. It turned out that when it gets into the air, the coronavirus can remain viable for three hours.

Also, the spray was sprayed on various surfaces from different materials. The virus lasted the longest on plastic and stainless steel – up to 72 hours. He lives on cardboard for no more than 24 hours, and on copper surfaces – a maximum of four hours.

Earlier that day, a study by Chinese scientists was published according to which coronavirus invades cells through the CD147 receptor. In this case, the virus binds to cells using its own protein SP. The experiment showed that a drug based on antibodies to CD147 inhibits the further spread of the virus in cells.

On March 11, the World Health Organization announced the outbreak of the new coronavirus COVID-19 as a pandemic. More than 200 thousand people in more than 150 countries are already infected in the world, the majority have recovered, about 8 thousand people have died.
