Face masks are an essential accessory when going outdoors to protect yourself from dust, smoke, and bacteria that can affect your health. With the evolving complexity of the Corona epidemic, the article below will provide you with more detailed information on choosing the right mask to protect yourself from the Corona virus.
1. Medical Masks
According to experts and doctors, while wearing medical masks can help prevent the spread of the Corona virus to some extent, it does not provide a 100% guarantee. However, medical masks are inexpensive, easily accessible, and user-friendly.
PGS.TS Tran Dac Phu, former Director of the Department of Disease Control, Ministry of Health, advised people not to panic and to know how to protect themselves. He recommended avoiding contact with people showing symptoms of pneumonia or other illnesses to minimize the risk of infection.
2. N95 Masks
N95 masks are designed to filter out 95% of fine dust particles of 0.3 microns in the air, which means they can theoretically provide better air filtration than medical masks. However, their actual effectiveness in preventing infectious diseases and viruses in the community is unclear and influenced by various factors.
Additionally, N95 masks are designed to fit tightly and may cause discomfort and difficulty breathing for those unaccustomed to wearing them. They are also not suitable for children due to their smaller face size and tend to be less effective for individuals with facial hair as they may not seal properly.
N95 masks can be misused: Due to their higher price and limited supply, people tend to reuse them. However, this practice can increase the risk of transmitting pathogens by touching the contaminated surface of the mask.
3. Effectiveness of the Two Types of Masks
A 2017 meta-analysis found that both types of masks are effective in preventing the spread of respiratory infections, but N95 masks did not show a significant advantage in preventing viral infections.
Since the primary transmission routes of the Corona virus are through contact and droplets (sneezing, coughing), many experts believe that medical masks are sufficiently effective at the community level.
4. How to Use Medical Masks Effectively
Wear the mask correctly: Use your thumb and middle finger to pull the loops of the mask and place them over your ears. The inner side of the mask should be in contact with your face. The inner side is usually lighter in color and smoother than the outer side.
Ideally, wear a mask only once a day and do not reuse or store it in your personal bag.
Wear the mask in the right direction: The top of the mask usually has a thin metal strip. When wearing the mask, use your thumb and middle finger to mold the metal strip to the shape of your nose, ensuring a tight seal along the bridge of your nose. The bottom of the mask typically has a soft, dimpled edge to provide a snug fit under the chin.
Depending on your family’s economic situation, you can choose a suitable type of mask to protect your health during hot and dusty days. This is especially important as the Corona respiratory epidemic rages on in Wuhan, with the potential to spread globally.
