Even if the new coronavirus leaves the cells for culture, it is detected in the air up to an hour after a particulate condition called "aerosol", and the infection capacity is maintained, a team such as the National Institutes of Health announced by March 18. It was found to remain on plastic for up to 72 hours. The team said it was "important information to keep the spread of infection."

The main cause of the infection is the spray spewing out by the cough and sneezing of the infected person, and the diameter is about 1 mm. It flies by a meter, but it falls in a short time depending on the weight. Since aerosols float in the air for longer periods of time smaller than this, the risk of infection increases when infected viruses are included.

According to the team, the new coronavirus maintained infection with up to 72 hours of plastic, as well as stainless steel, which is commonly used in kitchen facilities. It disappeared in 4 hours on copper and 24 hours on cardboard.

The virus will not be able to maintain its activity once it leaves the infected cells, but it was not clear how long it would take for the new coronavirus.
