The German authorities has made it obligatory to wear respiratory masks covering mouth and nose (MNC) as an effective strategy to battle SARS-CoV-2 infections. In many countries, this directive has been extended on shopping malls or public transportation. The aim of this paper is to critically analyze the statutory regulation to wear protective masks throughout the COVID-19 crisis from a medical standpoint.


We performed an intensive query of the newest publications addressing the prevention of viral infections including using face masks within the community as a technique to stop the spread of the infection. We addressed the issues of practicability, professional use, and acceptability based on the community and the surroundings the place the user resided.


Upon our critical evaluation of the available literature, we found only weak proof for wearing a face mask as an efficient hygienic device to forestall the spread of a viral infection. Nonetheless, the usage of MNC appears to be linked to related protection throughout close contact eventualities by limiting pathogen-containing aerosol and liquid droplet dissemination. Importantly, we discovered evidence for significant respiratory compromise in patients with extreme obstructive pulmonary illness, secondary to the development of hypercapnia. This might additionally occur in patients with lung infections, with or without SARS-CoV-2.


Epidemiologists at present emphasize that wearing MNC will successfully interrupt airborne infections within the community. The government and the politicians have adopted these suggestions and used them to both advise and, in some cases, mandate the overall population to wear MNC in public locations. General, the results appear to suggest that there are some clinically relevant eventualities the place the use of MNC necessitates more defined recommendations. Our critical analysis of the literature each highlights the protective effects of sure types of face masks in defined risk groups, and emphasizes their potential risks.


The knowledge that using face masks delays the SARS-CoV-2 transmission is quickly gaining popularity within the normal population. Politicians want steerage on how masks ought to be utilized by the general public to struggle the COVID-19 pandemic crisis. In this assessment, we summarize the relevant literature on this topic.
