The use of personal protective equipment (PPE), such as face masks can reduce the spread of infection when used correctly and in the appropriate context. This may be recommended in workplaces where people are more likely to come in contact with the coronavirus disease.

When to use a mask

- If you are healthy, you only need to wear a mask if you are taking care of a person with suspected 2019-nCoV infection.

You should wear a facemask when you are around other people (e.g., sharing a room or vehicle) and before you enter a healthcare provider’s office.

If you are not able to wear a facemask (for example, because it causes trouble breathing), then people who live with you should not stay in the same room with you, or they should wear a facemask if they enter your room.

- Wear a mask if you are coughing or sneezing.

- Masks are effective only when used in combination with frequent hand-cleaning with alcohol-based hand rub or soap and water.

- If you wear a mask, then you must know how to use it and dispose of it properly.

How to put on, use, take off and dispose of a mask

- Before putting on a mask, clean hands with alcohol-based hand rub or soap and water.

- Cover mouth and nose with mask and make sure there are no gaps between your face and the mask.

- Avoid touching the mask while using it; if you do, clean your hands with alcohol-based hand rub or soap and water.

- Replace the mask with a new one as soon as it is damp and do not re-use single-use masks.

- To remove the mask: remove it from behind (do not touch the front of mask); discard immediately in a closed bin; clean hands with alcohol-based hand rub or soap and water.
