People who are sick, those who take care of sick people, health workers or people on any situation of risk should follow this advice to stay safe and healthy

If you are healthy, you only need to wear a mask if you are taking care of a person with suspected Covid 19 infection.
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.
How to use masks:
If you wear a mask, then you must know how to use it and dispose of it properly.
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.
