At high risk of infection without mouth and nose protection, medical masks or FFP2 effectively protect. The good news is that if you both wear medical masks, or better yet, FFP2, your risk is drastically reduced. If both infected and uninfected people wear tight-fitting FFP2 masks, the maximum risk of infection after 20 minutes is just over one in a thousand, even at the shortest distance. The comprehensive study also confirms the intuitive assumption that to effectively protect against infections, in particular, an infected person should wear a mask that filters as much as possible and fits snugly to the face.
Wearing a face covering or mask has been shown to greatly reduce the release of droplets that can carry infectious particles in people’s mouths. The CDC states that healthcare workers should wear a NIOSH-approved N95 respirator (or equivalent or better) or face shield (if one is not available) and face shield or goggles as part of their personal protective equipment while suspected or diagnosed Patients infected with SARS-CoV-2 must wear masks or face coverings during transport. Don’t wear a knitted scarf or balaclava as protection, the CDC says. The CDC recommends not wearing a face covering without a mask because it does not prevent tiny air droplets that can float under and inside the face covering.
In other words, wearing a face mask primarily means protecting others. In East Asian societies, one of the main reasons for wearing a mask is to protect others from oneself. Wearing a mask has been defined as pro-social behavior where you protect others in your community. In enclosed public places such as busy shopping malls, religious buildings, restaurants, schools, and public transportation, you must wear a face mask if you cannot maintain physical distance from others.
Masks may occasionally be removed while eating and drinking, and when it is not possible to wear them due to the nature of the activity. It is important to note that the use of a face mask in the case of COVID-19 has obvious medical/medical implications, although face masks are used in many occupations to protect workers from inhaling dust or harmful substances. It is medical masks that serve as the standard for all other (various) face coverings. The argument against using homemade masks and face coverings is that homemade masks will be many times less effective than medical masks in preventing transmission of the virus to the wearer and almost useless in protecting the wearer.
Even when children are feeling well, wearing a mask in public can help stop the spread of COVID-19 and protect their family, community and themselves. If you are one of the people most at risk of becoming seriously ill from COVID-19, you must wear a medical mask. Face masks are encouraged as part of personal protective equipment and as a public health measure to prevent the spread of the 2019 coronavirus (COVID-19) pandemic. Masks with hard electret filters, such as N95 and FFP masks, must fit snugly against the face for full protection.
