The UAE reported 1,061 new Covid-19 cases on Tuesday, as it passed the 100,000 mark. Health officials said six people died, the highest single-day figure since May, taking the toll to 435. The number of recoveries reached 90,556, with a further 1,146 patients given all-clear by the authorities. The latest infections were detected after 102,349 tests were carried out in the past 24 hours. The Emirates has carried out more than 10.2 million coronavirus tests since the beginning of the outbreak and recorded 100,794 cases. On Tuesday, Dubai Economy shut down the office of a property company for flouting social-distancing rules. Inspectors from the agency's Commercial Compliance and Consumer Protection Sector carried out raids and issued fines to six commercial establishments for not adhering to face-mask rules. Two other businesses were hit with fines for overcrowding in their premises. The businesses were in the Muraqqabat and Naif area of Deira and Al Thanyah. Another shop was warned for not placing floor marking to help customers maintain physical distancing. Meanwhile, the Centres for Disease Control and Prevention, the US public health agency, said Covid-19 could spread through tiny particles that can linger in the air for hours. The CDC has until now not made a direct link about the role airborne transmission is playing in the spread of the virus. But on Tuesday the health agency said aerosolised virus particles can, and do, infect others under "certain circumstances". The new guidance acknowledged the virus can linger in the air – although it insists such transmission remains “uncommon”. On Monday, the head of emergencies at the World Health Organisation estimated that roughly one in 10 people worldwide (of 7.8 billion population) may have been infected by the coronavirus. More than 35 million cases of Covid-19 have been registered worldwide but WHO estimates the actual figures maybe more than 20 times the official count. Globally, more than 24.6 million have recovered from the virus while the death toll has crossed the one-million mark.
