USA healthy officials including the WHO and CDC previous told the general public that there wasn’t any need to wear a mask unless you feel like you are having the symptoms of corona virus or you came in contact with an infected individual. However,according to CNN, many of the officials now advise the citizens to wear a mask if they want to protect their economy, reopen schools and save lives.

Dr Robert Redfield from Centers of Disease Control and Prevention further said that if the whole country wears masks for the next four to twelve months, the corona virus transmission would slow down. Because the corona virus is highly contagious, if people wear mask, stay at home and take other prevention measures that are necessary, it would help control the virus because there are chances of the virus spreading without symptoms either from asymptomatic carriers or pre-symptomatic carriers.

Because the virus has an incubation period of up to two weeks, there are chances of the infected person passing it on to two or more people. The corona virus infected people may be contagious 48 hours before they get the symptoms making the transmission more blind. According to University of Washington’s Institute for Health Metrics and Evaluation, if more than 95% of American wear face mask in public, it would prevent the deaths of 33000 people by October 1.
