Preventive measures for Coronavirus SARS-CoV-2
These measures may help prevent infection with SARS-CoV-2 and other respiratory viruses, such as influenza, the common cold and respiratory syncytial virus (RSV).
How to perform proper hand hygiene
To reduce the risk of transmission of respiratory viruses, the following general protective measures may be applied:
Wear the mask.
Wash your hands frequently using soap and water or alcohol-based hand sanitisers.
Use tissues and wash your hands immediately.
Use of face masks
The use of a face mask is recommended in indoor settings where a safe distance of 1.5 metres cannot be maintained. Masks help prevent viruses from being released into the environment when a person sneezes or coughs. They are therefore an effective measure to reduce transmission during outbreaks of respiratory viruses, whether coronavirus or influenza.
The WHO recommends these guidelines for proper mask use:
- Ensure the mask covers both the mouth and nose and fits snugly, minimising any gaps between the mask and the face.
- Avoid touching the mask while wearing it.
- When removing, do not touch the front of the mask; remove it using the straps from behind. Once removed, wash your hands.
- Replace a damp mask with a clean and dry one.
- Single-use masks should be discarded after use and not reused, as they do not guarantee adequate protection.
