Since the outbreak of the novel coronavirus officially known as Covid-19 (coronavirus 2019), The World Health Organization (WHO) and other localized disease control agencies have always emphasized the use of the face mask to curb the spread of the viral infection in humans. The first-of-its-kind with pathogen name SARS-CoV-2 is also deemed by the World Health Organization (WHO), as a faster spreading strain than other coronaviruses.
Virologists suggest that that the use of face masks alongside the practice of other preventive measures, such as frequent hand-washing and social distancing, helps slow the spread of the virus. Meantime, while the world awaits a breakthrough vaccine that efficiently cures the virus, preventive measures must be observed with full compliance in all social and health care settings.
Why use masks for new crown pneumonia
Like most viruses and bacteria, the new coronavirus can be spread through the air and is contagious. Infected people usually spread the virus through their mouths when they cough or sneeze. Therefore, these respiratory reactions will pollute public air, objects and hard surfaces with harmful droplets and virus particles large and small.
Wearing a mask can reduce the risk of contracting airborne infectious diseases. For the current pandemic, mask culture provides the world with an opportunity to reduce the possibility of group infection in a cheap and simple way. This is because the correct wearing of a mask allows the user to inhale a certain percentage of healthy filtered air in an environment where the spray, splash and mist are highly likely to be contaminated.
The mask looks like a very simple tool, but it plays a very good filtering role in preventing harmful inhalation. However, the best protection is more than simply using a mask. Users must also comply with relevant guidelines and hygiene tips when handling and using masks.
Types of masks
There are usually three types of masks, namely:
1. Surgical mask
Surgical masks are the most common medical masks. They are medical grade and can reliably filter air contaminated by COVID-19. As a respiratory consumable, surgical masks need to closely fit the nose and chin area of the mask wearer, and have a soft texture and lining. Their absorbable ingredients make it easier for them to stick to the saliva and other respiratory secretions of mask wearers, thereby reducing contact with community members.
Currently, various shapes and sizes can be purchased onlineSurgical mask. However, because they are disposable and convenient to use, the market demand is high, which makes a convenient and hygienic facial covering solution available in public places such as churches and offices, ready for use.
2.N95 protective mask
The N95 mask is a medical grade variant design and an upgraded version of surgical masks. As the name suggests, this mask can filter up to 95% of pollutants during the inhalation of air. Some of these masks also have a built-in valve, which automatically closes when the user breathes in air, and opens when exhaling to flush out unfiltered air.
The N95 protective mask fits more closely and is designed for one-time use like a surgical mask. Their filtration accuracy makes them ideal for high-risk polluted environments.
3. Cloth mask
Due to the shortage of medical-grade masks, cloth masks have become popular as a temporary substitute and customized masks. These masks may include scarves, handkerchiefs and masks made of homemade materials and fabrics.
Generally, cloth masks are reusable and tailored to the design of surgical masks. Therefore, these variants are also tightly woven and stitched with multiple layers of fabric. Cloth masks can also provide a security level of protection. They can filter viruses and bacteria up to 50% and reduce contact with respiratory droplets and other secretions.

2. Do not share masks (whether they are reusable or disposable).
3. Be sure to check whether the mask is worn before use.
