The use of face masks in schools and good ventilation systems are more important than social distance to prevent the spread of COVID-19 through the air. This was disclosed in a medical study conducted in the USA, and the results of this study were published in the Medical Journal, Journal of Physics of Florides.
Research from the University of Central Florida has shown that a social distance of 6 feet is not required to prevent the spread of the virus through the air when the use of a face mask is needed. The researchers said the study was important because it provided guidance on how to ensure the safety of students within the walls.
He added that the results indicate that the reduction in the spread of the disease with face masks is no less than the increase in social distance, which shows the importance of mandatory use of face masks in schools and other places.
For this research, researchers developed a computer model of a classroom with students and a teacher and estimated the spread of the virus through the air by modeling the flow of air and the spread of disease. The researchers analyzed these models in a classroom with adequate ventilation and poor ventilation.
The results showed that the use of face masks is useful to avoid airborne particles. Similarly, in a well-ventilated room, the risk of COVID-19 is reduced by 40 to 50 percent because of the constant flow of air in such rooms.
The researchers stated that the use of face masks does not grow the risk of disease from a social distance of 3 feet and these findings could be applied to schools and businesses. He also said that the use of ventilation systems and face masks are essential for the spread of the virus.
