Abu Dhabi is now requiring people arriving by air to wear wristbands during their mandatory two-week quarantine. The measure is a sign authorities in the United Arab Emirates are tightening restrictions as daily COVID-19 cases reach all-time highs.

The latest regulations stipulate that travelers flying into Abu Dhabi International Airport self-isolate for 14 days. They must wear a “medically approved wristband” for the duration, an Etihad Airways spokesperson told Al-Monitor on Thursday. Abu Dhabi-based Etihad is the UAE’s flagship carrier. Immigration authorities will provide travelers with the wristband after they are cleared to enter the country, according to the spokesperson.

The wristband presumably tracks the movements of those wearing it to ensure they are abiding by the mandatory quarantine. Jordan has also used a tracking wristband to monitor people flying into the country.

In addition to the wristband, everyone flying into Abu Dhabi must be tested for the coronavirus upon arrival, except children under 12. Diplomats, children, people with chronic illness and the elderly are exempt from wearing the band, though these groups still must self-isolate, according to the airline.
