It has been shown that the virus can survive for up to three hours after coughing. In a small droplet, whose size is 3 to 5 micrometers (3 times thicker than a human hair), the SARS virus survives for several hours. Stronger things like a door handle, lift button and kitchen worktop can last about 5 hours.
Life expectancy for coronavirus outside the human body is not yet clear. Some studies have shown that other coronaviruses, such as SARS and mars, can survive for up to 9 (nine) days on iron, glass, and plastic. Some coronavirus viruses can survive for up to 25 days in a cold place. So a worm room is better than a cold room.
How You Can Kill coronavirus?
Studies have shown that coronavirus can be deactivated in a minute by mixing liquids with 61-71% alcohol. High temperature and humidity can also cause rapid death of other coronaviruses. The coronavirus responsible for SARS has not been able to survive at temperatures higher than 56 ° C. . Some disinfectant agents effectively reduce coronavirus infectivity within 1 minute such 62%–71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite
Taking a hot bath does not prevent the new coronavirus disease
During the coughing of a person suffering from coronavirus, Covid-1 can be spread by aqueous particles or droplets released through the nose and mouth. Scientists say 3000 droplets can be released from coughing only once. These particles of droplets can be on each other’s clothing surrounding objects. However, some small particles can also pass through the air.The virus has been found to live longer in the stool and urine. The virus can spread to many more with the touch of his hand without washing his hands well back from the toilet .
