Social distancing of two meters is not enough without face mask – Research

Corona Virus


Covid-19: Vaccination campaigns are going on around the world for the prevention of corona virus infection. However, wearing a face mask for protection from the virus has also become a new habit. This will be necessary till that time the epidemic is not controlled because the corona virus can spread very easily and make you sick. Now, researchers say that a two-metre social distancing guideline without a mask is not enough to stop the spread of indoor Kovid-19.

To prevent the spread of indoor corona, a distance of two meters without wearing a mask is not enough.

This disclosure has come from the research done by McGill University in Canada. However, the use of face masks inside the boundary wall can reduce the risk of getting sick from viral particles present in the air by 67 percent. Researchers said that the use of face masks and a good ventilation system are extremely important to prevent the spread of more infectious strains of corona, especially as the cold and flu season is about to start. Although most health guidelines recommend two meters of social distancing for families, researchers say that distancing alone is not enough to stop the spread of corona.

There should also be a good system of mask and ventilation to protect against corona.

According to research published in Building and Environment, researchers found that when people are not wearing masks, more than 70 percent of the viral content is spread more than 2 meters within 30 seconds. In contrast, if a mask is worn, less than one percent of the viral fraction can cross a distance of 2 meters. The scientists developed a computer program using the model to test the flow of liquids and gases to accurately measure the distance between the coughing particles within the boundary wall.

They found that airflow, the way a person is sitting or standing, and wearing a face mask markedly affected the spread of the viral portion. Significantly, cough is considered one of the important sources of virus spread through the air. According to the researchers, the research will help understand how the infectious material can spread from source to environment and help policymakers decide on guidelines for face masks.
