Some groups recommend that all members of the public wear masks, while others recommend that only COVID-19 patients and their caretakers should wear masks.

Additionally, public health agencies of different countries and territories have changed their recommendations regarding face masks over time.

Face masks have been been made compulsory in Budapest on public transport, in shops, markets and taxis from Monday 27 April.

For any type of mask, appropriate use and disposal are essential to ensure that they are effective and to avoid any increase in transmission.

The following information on the correct use of masks is derived from practices in health care settings.

- Place the mask carefully, ensuring it covers the mouth and nose, and tie it securely to minimize any gaps between the face and the mask.
- Avoid touching the mask while wearing it.
- Remove the mask using the appropriate technique: do not touch the front of the mask but untie it from behind.
- After removal or whenever a used mask is inadvertently touched, clean hands using an alcohol-based hand rub or soap and water if hands are visibly dirty.
- Replace masks as soon as they become damp with a new clean, dry mask.
- Do not re-use single-use masks.
- Discard single-use masks after each use and dispose of them immediately upon removal.
