Those directly serving tourists such as receptionists and restaurants' staff will be tested every three days.

All staff must wear masks and gloves and establishments need to have at least one quarantine room to deal with suspected Covid cases.

Tour guides and drivers must undergo Covid rapid testing every three days.

All tourists must also wear masks and comply with all pandemic prevention measures.
