Abu Dhabi set out new entry rules to come into effect from Monday.
Under the new directives, every person travelling to the emirate must present a negative PCR test result received within 48 hours or a negative result from a DPI test no more than 24 hours earlier.
The regulations were part of new measures announced by Abu Dhabi's Emergency, Crisis and Disasters Committee late on Thursday evening.
The new testing rules will apply to vaccinated and unvaccinated members of the public.
Presently, those who received their second dose of a Covid-19 vaccine more than 28 days ago would be given E status on the Al Hosn app.
E status would allow entry to the capital from other emirates. E status could be maintained by taking a PCR test every seven days.
Separately, Abu Dhabi will reintroduce its overnight sterilisation programme from July 17, asking all to stay at home from midnight until 5am unless securing a police permit. There were also new capacity limits for public places announced.
