Face mask and respiratory hygiene. WHO and other public health institutions including US CDC, provides for wearing for face mask covering nose and mouth in public settings or places where transmission is easy. These covering limit the travel distance and volume of respiratory droplets emerged out of breathing, coughing, sneezing and talking. It reduces the chances of infection by filtration of inhaled and exhaled air. Health care people are recommended to use N95 or equivalent respirators in addition to the other protective measures.

Social distancing. Social distancing or physical distancing is maintaining recommended distance between individuals at the place of public setting. It helps in controlling of spread of virus as it limits the contact between individuals.

On porous surface, the virus dies faster in comparison to the non porous surface. The surface must be disinfected with the help of sanitizers in case of any suspicion of infection. Moreover, the surface of public areas must be disinfected at regular intervals so as to control the spread. Ventilation and air filtration is recommended too in public places as one of the preventive measures.
