Face masks: benefits and risks in the course of the COVID-19 crisis

The German government has made it obligatory to wear respiratory masks covering mouth and nostril (MNC) as an effective strategy to fight SARS-CoV-2 infections. In lots of nations, this directive has been extended on shopping malls or public transportation. The goal of this paper is to critically analyze the statutory regulation to wear protective masks in the course of the COVID-19 disaster 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 way to stop the spread of the infection. We addressed the issues of practicability, professional use, and acceptability based on the community and the atmosphere the place the consumer resided.


Upon our critical evaluation of the available literature, we found only weak evidence for wearing a face mask as an efficient hygienic tool to stop the spread of a viral infection. Nonetheless, the use of MNC seems to be linked to related protection during close contact situations by limiting pathogen-containing aerosol and liquid droplet dissemination. Importantly, we discovered proof for significant respiratory compromise in patients with extreme obstructive pulmonary disease, 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 in the community. The federal government and the politicians have followed these recommendations and used them to each advise and, in some cases, mandate the overall population to wear MNC in public locations. Total, the results appear to suggest that there are some clinically related eventualities where using MNC necessitates more defined recommendations. Our critical evaluation 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 the usage of face masks delays the SARS-CoV-2 transmission is rapidly gaining fashionableity within the basic population. Politicians want guidance on how masks ought to be used by the general public to struggle the COVID-19 pandemic crisis. In this assessment, we summarize the related literature on this topic.

“The surgical face mask has turn into a logo of our times.”

On March 17th, 2020, this was the headline of an article within the New York Instances on the function of face masks throughout the COVID-19 outbreak. Face masks have change into a clothing accessory that is worn daily and everywhere. A wide range of shapes, forms, and supplies are being used and advertised to the purpose that in 2020 the enterprise of producing and selling face masks was born.

In Germany, the federal government has dominated that wearing a face mask is compulsory to protect the population from any risks of airborne illness, in line with the constitutional law [1] stating that “Protection should be simply provided to each citizen in the country.”

The intention of this paper is to analyze and critically focus on the laws of some Federal States in Germany, which require protective masks in public to conform to related laws already in place in other countries.
