Abstract
AbstractPrevious pandemics have shown that facemask use becomes highly popular in public settings due to fear of the disease spreading. There is, however, a lack of strong scientific evidence that facemasks can significantly reduce the spread of respiratory diseases and as such, most governing policies do not mandate these coverings. There is a stark contrast between the policies and acceptance of facemasks across different geographies. In this work, several data sources have been thoroughly analysed to elucidate how viral diseases are transmitted and spread with particular emphasis on the novel SARS‐CoV‐2 virus which is causing an outbreak of COVID‐19. The different types of facemasks and respirators are also explained, the nature of their design and their efficacy is also examined. Several key factors which have been hypothesised to contribute to the spread of viral infections are elaborated in detail including the effect of temperature and humidity, public transportation systems, population density, socio‐economics and sociology. In this work, data are analysed to explain how the disease is spread, how facemasks function and the differences in the number of initial cases based on several contributing factors to the spread of disease. There are also some dangers in automatically recommending community facemask wearing, such as a reduction in the immune system functionality from the reduced exposure to microbes and the disposal issues which result from the large‐scale use of such materials. The questions of whether facemasks are useful in a community setting or if they divert valuable material away from critical healthcare providers are discussed.
Highlights
The severe acute respiratory syndrome (SARS) outbreak of 2003 took a huge toll on lives and the economy and highlighted the importance of personal protective equipment (PPE) and face masks for front-line staff. 17 years later, the outbreak of SARS coronavirus 2(SARS-CoV-2) is significantly more widespread to nations all over the world
Facemasks are routinely used by healthcare workers to prevent the entry of droplets into their respiratory tract, it is reasonable to expect that the use of such masks will have a positive effect in the prevention of transmission
As the disease is known to spread via asymptomatic carriers, the wearing of facemasks may help to reduce the spread of the disease
Summary
The severe acute respiratory syndrome (SARS) outbreak of 2003 took a huge toll on lives and the economy and highlighted the importance of personal protective equipment (PPE) and face masks for front-line staff. 17 years later, the outbreak of SARS coronavirus 2(SARS-CoV-2) is significantly more widespread to nations all over the world. The normality of public facemasks in China has increased social acceptability and there is less embarrassment compared to countries with low susceptibility of such previous diseases, such as with the United States.
