The wearing of masks is one of the many layers of protection needed to fight against COVID-19. Although the use of masks at the start of the pandemic was controversial, today, many solid data point to the effectiveness of masks as protection against respiratory diseases.
The use of face masks is beneficial, especially in areas where physical distancing is not possible. Wearing these masks in public works in two ways. Firstly, it protects the public from infected individuals, especially those who are carrying the virus without showing any symptoms.
Several studies have shown how transmission via inhalation can occur because infected particles can linger and travel on air within a distance of six feet or more.
A medical face mask acts as a barrier against droplets and aerosols that can enter your nose, eyes and mouth. It partly filters out infected particles that are floating in the air.
Secondly, the use of face masks in public prevents the infected person from spreading it to the public. This is termed as source control. A face mask blocks virus-containing particles from being released into the air during exhalation.
The main source of transmission for COVID-19 is through exhalation from those who are carrying the virus. These inhalation droplets are released when people talk, cough, sing, sneeze or laugh.
The risk of exposure increases when people are in enclosed spaces, such as in public transport and offices. The infected person may not show symptoms in the early stage of the infection, so wearing face masks is the best option in preventing community transmission.
Furthermore, transmission is 7.5 times higher in countries without a mask mandate compared to those that have. The reproduction number of the virus is also significantly reduced when 80% of the population are wearing masks, which can help in putting an end to the virus.
The World Health Organization does not recommend wearing a mask when doing vigorous exercise because it can affect your breathing capacity, and the effectiveness of the mask is compromised when it is wet or damp.
Exercising outdoors is the best option in reducing the risk of catching the virus. However, if you have to work out in a gym, always keep a safe distance of at least 1 metre away from others.
It is also important to note that there is an increased risk of droplet transfer from those who are exercising due to the increase in respiratory volume and ventilation during exertion.
Little protection is better than no protection at all. However, certain face masks may not serve their purpose and can expose people to the disease.
When choosing a face mask, avoid those with exhalation valves because they allow viruses to escape through the valves. Masks with vents or holes defeat the goal of wearing a mask.
There was a shortage of face masks for sale early during the pandemic, which resulted in the popularity of cloth face masks. Unfortunately, cloth face masks do not offer the same protection as medical-grade face masks. However, when there is a lack of supply, putting several layers of fabrics can help minimise transmission.
Proper use of a mask is vital in preventing the spread of the virus and protecting yourself from getting it. Here are some tips on how to properly use a mask.
The use of face masks is effective in preventing the transmission of COVID-19 among the public. Together with regular washing of hands and maintaining physical distance, this can help curb the spread of the disease and save lives.
