At first, there was a significant lack of masks for frontline workers, which was why the authorities were hesitant to advise wearing masks to the public at large. This is reasonable why people would glance back at this old guidance and not know what to believe in. We must respect public health scientists and understand that their opinions can shift when more evidence becomes accessible. It took years for the spread of HIV to be completely recognized. People who followed new guidelines for healthy measures in the initial periods of HIV did not compensate as much as anyone who took steps to defend themselves and their loved ones.
Coronavirus is predominantly spread from person to person through a respiratory spray. Staying away from people (social distance) and reducing the germs exchanged between people are also strategies to minimize the spread of the virus. Although high-quality work on mask usage is minimal, all evidence support wearing masks as a key indicator of public safety to minimize viral spread.
How effective are these masks?
The premium quality N-95 mask from the medical mask manufacturer is 95 percent successful in holding the user clear of inhaling virus particles. Such masks are also ideally intended for front-line staff in high-risk environments where aerosols of viral particles exist. Surgical masks are less efficient and the face-covering is much less successful in shielding the person. However, only a 50% decrease in the viral transmission is statistically significant.
To the public at large, the justification for using a face mask is to better shield people from you as you sneeze, cough, or just speak and shoot infectious droplets into the air. Some people who are infected that unconsciously transmit the COVID-19 virus because they have little to no symptoms. And wearing a mask displays a reverence for us, which is the way of trying to reduce the transmission of the disease. The mask must not be so bulky that breathing through them is unbearable. Filter inserts may not be appropriate and can render masks more difficult.
