Bacteria become inactive within 1 minute when sprayed with more than 75% of ethanol spray.

Corona 19 can also be spread by droplets (fine saliva and runny nose drops) that occur when an infected person coughs. Up to 3,000 drops of droplets when coughing once. These particles are dispersed to the surface of others, clothing, and other objects around them. The finer particles float in the air.

Viruses also survive longer in feces. If you don't wash your hands after going to the bathroom, you can easily contaminate the objects you touch later.
According to studies by SARS and MERS, these viruses survive on surfaces of metal, glass, and plastic for 9 days. Some have reported that they can survive up to 28 days at low temperatures.

The new coronavirus is known to survive well in various environments.

Recently, there was the first experiment to find out how long the new coronavirus survives on the surface of different materials. Virologists from the National Institutes of Health (NIH) participated.

The virus can survive for up to 3 hours in droplets from the air due to coughing.
In the absence of air movement, microscopic droplets of the size of 1-5 micrometers (about one-third of the thickness of a human hair) may remain for hours longer.

With an air purifier, the virus can float in the air for up to two hours.

The NIH, however, said the new coronavirus could survive up to 24 hours on box cardboard and 2-3 days on plastic and stainless steel surfaces. The virus survives longer on other hard surfaces, such as plywood countertops or plastic-coated handles. But on the copper surface, the virus appeared to die within four hours, the researchers explained.

Studies on the flu virus have revealed that droplets of cough droplets can contain tens of thousands of cold viruses.

Then how long will the virus survive in the clothes we wear? The team leader at the Rocky Mountain Labs said that natural fibers with good absorption can kill the virus quickly.
