How to protect yourself from COVID-19

First, in what cases do you need to wear a face mask?

Wearing face masks is an effective way of blocking the spread of respiratory secretions.

1. You should wear a face mask when visiting patients in the hospital, especially at fever or respiratory clinics.
2. Wearing a face mask is recommended when:

1) Travel on public transport in the high-risk season of respiratory infections
2) Spend a long time in a relatively confined space, such as supermarkets, shopping malls, cinemas, etc.
3) There are sick persons in your study or work areas
4) Close contact with patients or suspected patients

3. To prevent the spread of the viruses to others, please wear a mask when symptoms of respiratory diseases such as fever, cough, and runny nose occur.

Second, how to select a face mask?

There are different types of face masks, such as industrial and medical face masks. Currently, we have four commonly used categories of face masks:

1. Regular absorbent gauze face masks cannot be used for preventing infection, therefore, they are not recommended.
2. Disposable medical face masks.
3. Disposable medical surgical face masks consist of three layers: outer water and droplets resistance layer; middle particle filter layer; and inner moisture-absorbing layer.
4. Disposable medical protective face masks (known as N95 face masks) have a 95% filter effect, surface moisture resistance, and blood-blocking properties. Disposable medical surgical face masks can be used for our daily protection. When buying, please make sure that there are “medical-surgical masks” on the outer packaging of the selected face masks.

Third, how to properly wear face masks?

Always wash your hands before wearing a face mask. Avoid hand contact with the inside of the face mask to reduce the risk of contamination. Understand the inside, outside, up and down of the face masks: the light side is the inner layer and should be contacted to the mouth and nose, and the dark side is the outer layer. The metal strip (nose clip) indicates the up position of the mask. Do not wear the face mask inside out or on both sides alternately. The face mask needs to be replaced when getting wet. It is not recommended to wear a face mask for more than four hours.

1. 1. How to wear disposable medical face masks and disposable medical surgical face masks?

1) Expand the fold gently and completely

2) Cover the nose, mouth, and chin. For the face mask with straps, tie the upper strap to the top of the head and lower strap behind the neck. For other face masks, hang it directly on the ears.

3) Use your fingers to adjust the nose clip according to the shape of your nose.

4) Check the contact along the edges of the mask.

2. 2. How to wear disposable medical protective face masks?

1) Holds the protective face mask with one hand with the nose clip side outward. Cover the nose, mouth, and chin with the nose clip close to the face.

2) Use another hand to pull the lower strap over the head and place it under the ears behind the neck.

3) Then pull the upper strap to the middle of the head.

4) Place your fingers on the metal nose clip, starting in the middle, press the clip inward with your fingers, move and press to both sides to adjust the clip based on the shape of the nose.

3. 3. How to remove the face masks?

1) Do not touch the outside of the face mask (contaminated side).
2) Untie the lower strap and then the upper strap. Hold the strap of the mask with your finger and discard it into a medical waste bin.
3) Wash hands after removing the mask.
