Covid-19 spreads from one person to the other mainly through respiratory droplets. When an infected person who is physically close to you coughs, talks, sneezes, sings or shouts, their droplets travel in the air, landing on your mouth or nose. If you breathe the droplets, you are predisposed to a covid-19 infection.
Symptomatic and Asymptomatic Patients
People who are infected with coronavirus may be symptomatic or asymptomatic. Symptomatic patients show common symptoms like fever, dry cough, chills, fatigue, sore throat and loss of smell. The infection may also affect neurological functions, gastrointestinal symptoms or both in some people. In this case, they may or may not occur with respiratory symptoms. On the other hand, asymptomatic patients do not show any symptoms of the disease at all.
Wearing Masks to Reduce the Spread of Covid-19
Wearing a mask over your nose and mouth helps prevent the spread of respiratory droplets. Several studies indicate that asymptomatic and presymptomatic (people who are yet to show symptoms) patients can spread the virus to other people. As such, everyone needs to wear a mask whether they feel sick or not. Wearing a face mask keeps you safe from the people around you in case they are infected and not showing symptoms. You are also able to protect the people around you if you are the asymptomatic one.
Are All Masks Equal?
It is crucial that you put on a face mask every time you are getting to public. You, however, have to wear a mask when indoors with people you do not live with or infected people. Cloth masks and medical procedure masks generally work well in most circumstances. When visiting a park or talking with your neighbours outdoors while keeping a distance of 6 feet away from them, for example, a cloth mask or medical mask is enough. However, some situations have a higher risk of transmission hence the need for a mask that offers higher protection, and a KN95 mask has been found to offer increased protection.
When to Wear A KN95 Mask
A KN95 mask is the best for use in situations where you have to be in close proximity with people you do not live with for prolonged amounts of time. Such situations include when riding planes or using any form of public transport, especially one you cannot keep six feet away. You can also use it when talking to someone who is already infected and when working in places where you interact with so many people.
People Who Should Wear Masks
Everyone is generally expected to wear a mask at all times. To be specific:
- Any person above the age of two is expected to wear a mask at all times in a public setting.
- When travelling on a plane and other forms of public transport, everyone is expected to wear a mask.
- If you have a Covid-19 patient in your home, you need to wear a mask
- Wear a mask when around people who you do not live with, whether in your home or their homes.
People Who Are Exempted from Wearing Masks
There has always risen an argument on whether there are people who are exempted from wearing masks. In as much as everyone is required to wear a mask, sometimes CDC recognizes that it is not feasible at all times or to all people. The following categories of people are exempt from wearing a mask.
- Children under the age of two
- If they wear masks, it could create a risk to workplace safety, health, or job duty
- People who disability hinders them from wearing masks safely
