The UAE reported 993 new Covid-19 cases on Monday, pushing the total number of infections to 717,374. Daily cases remained below 1,000 for the seventh day in a row. It is the first time the country's seven-day rolling average has fallen below 1,000 since October 1, 2020. Another 1,501 people beat the virus, raising the recovery tally to 703,603. Health officials said an additional 321,470 PCR tests were conducted in the past 24 hours. The country has carried out more than 74.4 million tests since the beginning of the pandemic. One patient died in the 24-hour reporting period, taking the death toll to 2,039. There are 11,732 active cases in the country, a figure which has fallen steadily due to a recent trend of recoveries exceeding new cases. Mass screening and a nationwide vaccination drive have been key to the UAE's efforts to overcome the pandemic. More than 18 million doses of Covid-19 vaccine have been administered to the public. More than three-quarters of the public have received two doses of a vaccine. <br/> On Sunday, Abu Dhabi Emergency, Crisis and Disasters Committee said residents of the emirate who received their second shot of <a href="https://www.thenationalnews.com/uae/health/sinopharm-vaccine-in-uae-how-effective-is-it-against-covid-19-and-are-there-side-effects-1.1175488">Sinopharm’s Covid-19 vaccine</a> more than six months ago must have a booster dose by September 20.
