Wear a mask to prevent disease.
The World Health Organization (WHO) warns that there are two basic routes of infection of the new strain of coronavirus (SARS-CoV-2). The first is direct transmission through unprotected contact with nasopharyngeal droplets from coughing, sneezing, runny nose into the respiratory tract. The second is indirect infection through infected surfaces.
Why should you wear a mask to prevent disease?
For people who are not sick, wearing a mask is a measure to prevent droplets containing the virus from entering their own respiratory tract. As for people who are in the incubation period, wearing a mask has the effect of preventing the spread of the virus out. In this case, if you don't wear a mask, the nose and throat secretions containing the virus can shoot up to 2m away, very dangerous for people around.
Wearing masks the wrong way not only increases the risk of disease transmission but also wastes money. Because if an average person uses 3 masks a day and with a population of 10 million people like today, a day consuming up to 30 million masks is not necessarily effective, obviously too wasteful.
When to wear a mask?
According to the latest recommendation of the Ministry of Health, it is not necessary for people to wear masks at all times because it can cause confusion and discomfort. The Ministry of Health also specifies the following cases when it is necessary to wear a mask to prevent acute respiratory infections caused by Covid-19:
- When contacting, taking care of people infected or suspected of being infected with Covid-19.
- When caring for or in close contact with someone who has symptoms of a respiratory illness such as cough, difficulty breathing, runny nose, etc.
- When assigned to self-monitor, isolate at home or when visiting, examining, and treating at medical examination and treatment establishments. Healthy people without respiratory symptoms only need to wear cloth masks when going to crowded areas, on public transport.
What kind of mask should I wear?
Most masks such as medical masks, 3M masks, cloth masks, etc. can prevent droplets from people around such as coughing, sneezing, nasal mucus, spitting, etc. Face masks are scarce at present, people can use cloth masks or regular medical masks; Only for caregivers, patient treatment and people who go into the outbreak is it necessary to use N95 masks and other special specialized masks.
What is the correct way to wear a mask?
Masks only work to prevent disease if it is used correctly. Wearing a mask the wrong way not only wastes money but also loses its protective effect, increasing the risk of disease transmission. Here are some recommendations of the Ministry of Health on wearing masks properly to prevent the spread of Covid-19 as well as other diseases:
- Do not wear face masks upside down. For medical masks, wear the darker side out, the lighter side facing in, the aluminum clip facing up. When wearing, must cover both nose and mouth.
- Do not touch the mask surface with your hands while wearing it.
- Do not remove the mask when communicating, coughing, or sneezing in public.
- When removing the mask, just hold the ear strap to remove it.
- Do not use a dirty mask. For medical masks, use only once and then dispose of them in a safe, covered trash can. For cloth masks, it is recommended to wash the mask daily with soap for next use.
Is wearing a mask enough to prevent disease?
According to the recommendations of the Ministry of Health, to prevent the Covid-19 epidemic, wearing a mask is still not enough, it needs a full combination and at the same time many other measures such as:
- Wash your hands often with soap/quick hand sanitizer and clean water, especially after coughing, sneezing, after handling, grasping, or coming into contact with potentially hazardous items such as elevator buttons, door handles, stair handrails, after going to the toilet, after cleaning the child, before eating, when hands are dirty, before entering and after leaving the service area.
- Use a mask properly when going to a public place according to the instructions of the Ministry of Health and immediately discard the mask after use in the trash. Absolutely do not spit indiscriminately.
- Respiratory hygiene, environmental hygiene around contact surfaces.
- Vaccinate to boost immunity
