You can use medical masks to protect your health and avoid getting sick. To prevent bacteria and viruses from spreading, the masks are placed over the nose and mouth.
To prevent respiratory infections, there are two main types of masks: respirators and surgical masks. Which mask is most suitable for you will depend on the type and size (or infectious particles) that these masks can filter. Face masks are preferred for respiratory viruses that spread by droplets. Face masks can be loosely fitted to prevent sprays and droplets from spreading. Protect the face from contact with hands.
N95 mask block 95% airborne particles and these respirators prevent small infectious particles from being inhaled by the user. For measles and chickenpox, an N95 mask will be required. Children and people with facial hair cannot use N95 respirators as they are difficult to fit. A special respirator, called a powered-air-purifying respirator, may be used in these cases.
When is a mask necessary?
It is advisable to use a face mask only when you are coughing and sneezing. Face masks should be worn by health care workers as well as people who deal with patients with respiratory infections. But to avoid infection by corona virus or its variants, all people must use face masks. N95 and KN95 mask require special fitting testing. But they are not recommended to be used for general purposes.
How do you wear a mask?
Before applying a face mask, wash your hands with soap and water. An alcohol-based cleanser with at least 60% alcohol can be used if soap and water are unavailable.
After you have washed your hands, place the N95 mask on your nose and make sure there is no space between you and the N95 mask. Seal it tight. Avoid touching the mask while wearing it. If you accidentally touch the mask with your hands, wash them with soapy water and use hand sanitizer. Once you are done using the mask, remove it and don’t touch it again. Wash your hands again after removing the mask.
