The Abu Dhabi Emergency Crisis and Disasters Committee has updated entry requirements – including those for business, entertainment and sport – to include green status on <a href="https://www.thenationalnews.com/uae/health/how-to-maintain-green-pass-status-on-al-hosn-app-to-secure-safe-entry-to-some-abu-dhabi-venues-1.1238295" target="_blank">Al Hosn app</a> and a negative <a href="https://www.thenationalnews.com/world/uk-news/2021/10/08/what-is-the-difference-between-a-pcr-test-and-a-lateral-flow-test/" target="_blank">PCR test</a> result within 96 hours of entry. Attendees must also commit to wearing masks. The new measures are effective from Sunday, 31 October, the safety committee said. <a href="https://www.thenationalnews.com/uae/health/abu-dhabi-s-covid-19-green-pass-system-launched-in-pictures-1.1241481" target="_blank">Al Hosn green pass</a> rules came into effect in Abu Dhabi on September 19. Green status allows entry to many public spaces. The status of people who are fully vaccinated against Covid-19 remains green as long as they have a PCR test once every 30 days. People who received a second dose of the <a href="https://www.thenationalnews.com/uae/health/2021/08/11/what-are-the-sinopharm-vaccine-side-effects-and-is-a-pfizer-booster-shot-safe/" target="_blank">Sinopharm</a> vaccine more than six months ago must take a booster shot to maintain their green status. Authorities made that announcement last month and gave a 30-day grace period for people to receive the booster dose by September 20 to prevent their status from turning grey. Those whose Al Hosn app shows grey status are refused entry to many public spaces. The Al Hosn app makes it easier for contact tracing on a national scale, so the authorities can quickly contain the<a href="https://www.thenationalnews.com/world/coronavirus-latest-uae-tops-global-rankings-for-vaccination-rates-1.1215574"> spread of Covid-19</a>. When it is turned on for tracking, if you have come into close proximity with someone who has tested positive the authorities can warn you to self-isolate. The app also acts as a record of all your Covid-19 test results, so if you come up positive you know to stay at home. Evidence of your Covid-19 vaccination doses are also stored on the app, so you can use it to prove your status in the UAE. If you travel abroad, you can use Al Hosn app as a vaccine travel certificate. The app contains a colour-coded system to easily indicate your health status. If it turns red, it means your most recent test returned positive and you must seek the advice of the local health authority. The colour amber indicates that you need to be tested or retested because of possible exposure to Covid-19. Green indicates you have been tested and are Covid-19 negative. Grey indicates you have no recent test results. The letter E shows you have had your second dose of a Covid-19 vaccination at least 28 days ago, and a negative PCR test within the past seven days. If you want to keep your E status, you need to have a Covid-19 test every week. If you have had both doses of a Covid-19 vaccine, but they do not appear on the app, you should go back to the clinic where the inoculations were administered.
