Since Monday, 13th April 2020, it is mandatory to wear face masks to cover the wearer's mouth and nose.

If there is a shortage of face masks, other textile barriers such as a scarf may be used. It is essential that nose and mouth are covered. This measure is necessary to reduce the risk of infection with the coronavirus. The mouth-nose-protection serves primarily as a third party protection, to prevent the risk of transmission by withholding droplets during coughing, talking and sneezing. The safety distance of at least 1 metre to other people remains recommended, also while mouth-nose-protection is being worn.

Passengers are obliged to provide their own mouth-nose-protection. The large-surface distribution of mouth-nose-protection (face masks) is carried out by supermarkets.
