Under the COVID-19 epidemic, it is recommended to choose an appropriate mask type without excessive protection. According to the nature and risks of epidemic prevention, the following guidelines are proposed:

High risk exposed person

Type of personnel:

1. All staff working in wards, ICU and observation rooms where COVID 19 patients (confirmed cases, suspected cases) are admitted, including clinicians, nurses, carers, cleaners, cadavers, etc.
2. Doctors and nurses in the fever clinic of the designated medical institutions in the epidemic area.
3. Public health physicians conducting epidemiological investigations of confirmed and suspected cases.

Protection Suggestions:

1. Medical protective mask;
2. Install safety goggles or protective screen during the first aid of infected patients and tracheal intubation tracheal endoscopic examination.
3. When there is a shortage of medical respirator, the respirator can be used to replace the respirator that conforms to the standard of N95/KN95 and above, or the self-suction filter respirator can be used. (full or half face type) with filter cotton to prevent particles, and the protection effect of powered air filter respirator is better.

Higher-risk exposed person

Type of personnel:

1. Medical staff of emergency department, etc.;
2. Public health physicians conducting epidemiological investigations of persons in close contact
3. Environmental and biological sample testing personnel related to the outbreak.

Protection Suggestions:
PM respirator with N95/KN95 and above standard.

Medium risk exposed person

Type of personnel:

1. Medical staff of general outpatient service and ward.
2. Staff in crowded places, including hospitals, airports, railway stations, subways, ground buses, planes, trains, supermarkets, restaurants and other relatively closed places.
3. Engaged in epidemic related administrative management, police, security, Courier and other employees.
4. Home isolation and co-living personnel.

Lower-risk exposed person

Type of personnel:

1. Public in crowded areas such as supermarkets, shopping malls, vehicles and elevators
2. Indoor office environment;
3. Patients receiving medical treatment (except fever) from medical institutions;
4. Focus on learning and activities for children and students in preschool institutions.

3. Workers in well-ventilated workplace.

Protection Suggestions:
Masks are also not worn in homes, places with good ventilation and low personnel density. Non-medical masks, such as cotton, activated carbon and sponge masks have a certain protective effect, but also reduce the cough, sneeze and talk produced by the role of droplet spread, visible choice.

Usage precautions

Under the COVID-19 epidemic, on the premise of protecting public health, you can appropriately extend the use of masks (use time, use times).

Replacement of mask:

1. Medical standard respirators are used for a period of time, and the masks are only used by special personnel. When high-risk persons finish work, take off the protective devices in the entry path (drinking water), and go to the toilet, they need to be replaced after re-entering
2. Immediately replace the mask if it is contaminated by the patient’s blood, respiratory/nasal secretions and other body fluids;
3. High-risk personnel should be replaced after receiving highly coagulative patients;
4. Masks worn by other risk categories can be used repeatedly. Wash your hands before wearing the mask and avoid touching the inside of the mask. If the mask is dirty, deformed, damaged or smelly, it should be replaced in time.

Preservation, cleaning and disinfection of masks:

1. If the mask needs to be used again, it can be hung in a clean, dry and ventilated place or placed in a clean and breathable paper bag. Masks should be stored separately, avoid contact with each other, and identify mask users.
2. Medical standard respirator should not be cleaned, disinfectant, heating and other methods should not be used for disinfection.
3. The cleaning of self-priming filter respirator (full or half face type) and power air supply filter respirator shall be carried out according to the instruction manual.
4. Cotton mask can be cleaned and disinfected. Other non-medical masks should be handled according to the instruction.
