Outside the human body, viruses can also live for a time on different surfaces. According to the Centres for Disease Control and Prevention (CDC), it may be possible to contract with SARS-CoV-2 responsible for the current outbreak, COVID-19, by touching a surface or object with the virus on it and then touching the face. Studies show that the SARS-CoV-2 is mostly spread from person-to-person through respiratory droplets produced when an infected person coughs or sneezes.
Researchers studied the duration in which the virus survives in the air and on different surfaces by mimicking how viruses are spread by patient onto different surfaces in a household or hospital environment, through coughing, sneezing or touching the objects. Then, the team analyzed how long the virus remained viable on these surfaces.
The findings shows the importance of hand washing and sanitizing frequently touched objects and surfaces around us. Try to avoid touching your face mainly eyes, nose, and mouth. To prevent the spread of coronavirus, practice social distance and avoid close contact with those who are sick and stay home if you are sick yourself.
