With the current COVID-19 crisis situation and the rising number of cases When is it important to wear a mask?
COVID-19 spread from person to person via small respiratory droplets. These are generated when a person with the virus exhales, coughs, or sneezes. You can contract the virus if you breathe in these droplets.
Additionally, respiratory droplets containing the virus can land on various objects or surfaces. Touching a contaminated object or surface and then touching your eyes, nose, or mouth can also lead to infection.
Therefore, it is recommended to wear face masks in public settings.
Does everyone need to wear a mask?
Everyone needs to wear a mask in public settings. However, people with breathing issues shouldn’t wear masks. Neither should children under the age of 2 due to the risk of suffocation.
If you aren’t sure if a face mask is safe for you to wear, be sure to talk to your doctor. They can advise you on what type of face covering may be best for you if you need to be out in public.
Simple rules for effective masks usage
Dos
: Ensure that you use and wear an appropriate mask or respirator properly and consistently, according to its purpose as described on the instructions.
: Reduce the amount of talking when wearing a mask or respirator. These actions will lower the amount of condensation produced within the mask or respirator, and extend its effective life. Change masks or respirators if soiled or wet.
: Practice proper removal of used and contaminated masks or respirators to prevent the spread of viruses to your hands, face and other contact surfaces. Touch only the straps and not the surface of the mask or respirator when removing it. You should wash your hands after disposal of a used mask or respirator.
Don’ts
x Do not reuse masks or respirators as they are contaminated once used.
We will explore each of them in a little more detail below.

When purchasing a respirator, it is important to check that it is labelled with the NIOSH certificate number and is not expired. Some of these respirators have valves that allow exhaled air to get out, making it easier for the user to breathe. However, the downside of this is that other people are susceptible to the particles and pathogens that are exhaled through these valves.
A more commonly use respirator will be the N95 respirator and it is advisable to use it without valves.
An N95 respirator is a more tight-fitting face mask. In addition to splashes, sprays, and large droplets, this respirator can also filter out 95 percent of very small particles which makes it better than a surgical mask. This includes viruses and bacteria.
The respirator itself is generally circular or oval in shape and is designed to form a tight seal to your face. Elastic bands help hold it firmly to your face. Some types may have an attachment called an exhalation valve, which can help with breathing and the build-up of heat and humidity.
N95 respirators aren’t one-size-fits-all. They must be fit-tested before use to make sure that a proper seal is formed. If the mask doesn’t seal effectively to your face, you won’t receive the appropriate protection. A poor seal can lead to leakage, lowering the respirator’s effectiveness.
N95 respirators can become uncomfortable and stuffy due to their tight fit, making them difficult to wear for extended periods of time. N95 respirators are also intended to be disposable. However, researchers are testing ways to disinfect N95 respirators so they can be reused.
Surgical mask
Also known as medical masks, surgical masks are disposable, loose-fitting face masks that cover your nose, mouth, and chin. They’re typically used to:
01: protect the wearer from sprays, splashes, and large-particle droplets
02: prevent the spread of potentially infectious respiratory secretions from the wearer to others
There are various types of surgical masks. Typically, these disposable, single-use masks are cut into a rectangle shape with three layers of pleats or folds breathable synthetic fabrics that expand to cover your nose, mouth, and jawline. The top of the mask contains a metal strip that can be formed to your nose.
Unlike respirators, surgical face masks don’t have to meet filtration standards. They aren’t required to form an airtight seal against the area of your face that they cover. How well surgical masks filter pathogens varies widely, with reports ranging from 10 to 90 percent.
Despite differences in fit and filtration capacity, a randomized trial found that surgical face masks and N95 respirators reduced participant risk of various respiratory illnesses in similar ways.
Homemade cloth face mask
While N95 respirators and surgical masks and are in short supply around the world, cloth masks are more accessible and reusable. They are all intended to slow the spread of COVID-19.
Homemade cloth masks are less effective, offering a small degree of protection because most have gaps near the nose, cheeks, and jaw where tiny droplets can be inhaled. Also, the fabric is often porous and can’t keep out tiny droplets.
Although cloth masks tend to be less effective than their medical-grade counterparts, experimental results suggest they are far better than no mask at all when worn and constructed properly and may help lower the risk of people without symptoms transmitting the virus through speaking, coughing, or sneezing.
Can homemade masks capture smaller virus particles? To answer this question, the scientists tested 0.02 micron Bacteriophage MS2 particles (much smaller – a fifth the size of – COVID-19).
On average, the homemade masks captured 7% fewer virus particles than the larger bacteria particles. However, all of the homemade materials managed to capture 50% of virus particles or more (with the exception of the scarf at 49%).
NOTE: Wash homemade cloth masks after every use. When removing, be careful not to touch your eyes, nose, and mouth. Wash hands immediately after removing.
Other effective ways to prevent COVID-19
There are other effective ways besides using face masks to prevent becoming ill with COVID-19. These include:
Washing our hands with soap more frequently or use alcohol-based hand sanitizer.
Practicing social distancing. Avoid contact with people who are sick, and stay at home as much as possible
Being conscious of your face. Only touch your face or mouth with clean hands.
