Coronavirus live news: US passes 280,000 deaths, Australian state of Victoria eases restrictions | World news

Here is some more detail on the easing of restrictions in Australia’s Victoria state, which has recorded 37 days without any new coronavirus infections.

From midnight on Sunday, up to 100 people will be able to attend public gatherings such as weddings, with density rules of one person per two square metres remaining in place, while 50% of office workers will be able to return to workplaces by 11 January, up from 25% now, the state’s premier said.

“Today we can take some big steps, not to normal, but to a Covid-safe summer (but) we all need to remain vigilant and we all need to play our part,” Premier Daniel Andrews told a news conference.

Masks will remain mandatory at indoor venues and on public and ride-share transport, he said.

Public health concerns eased after two travellers who returned from Germany, bypassing quarantine in Sydney to travel straight to Melbourne, returned negative Covid-19 tests.

All passengers on the Saturday afternoon domestic flight between the two cities and some airport staff must remain in self-quarantine until the results from a second test arrive on Monday, a health official said.

Australia recorded seven new cases overnight, all returned travellers. The country has all but stamped out the coronavirus through strict quarantine measures, particularly in Victoria, the second-most populous state, which in early August logged as many as 700 daily infections.

In the UK, singer Rita Ora has apologised after reports emerged that she should have been self-isolating when she celebrated her birthday at a London restaurant last month.

The 30-year-old flew to Egypt in a private jet on 21 November to perform at the five-star W Hotel in Cairo, an appearance for which she was paid a six-figure sum, the Mail on Sunday reported.

She returned to England the next day and was required, as per government quarantine rules, to self-isolate for 14 days.

Instead, Ora attended her own birthday party at the Casa Cruz restaurant in Notting Hill, west London on 28 November – itself a breach of coronavirus restrictions for which she has previously apologised.

Mexico’s health ministry on Saturday reported 11,625 new confirmed cases of coronavirus infection and an additional 593 fatalities, bringing the total in the country to 1,168,395 cases and 109,456 deaths.

The government says the real number of infected people is likely significantly higher than the confirmed cases.

Britain is preparing to become the first country to roll out the Pfizer/BioNTech Covid-19 vaccine this week, initially making the shot available at hospitals before distributing stocks to doctors’ clinics, Reuters has reported.

The first doses are set to be administered on Tuesday, with the National Health Service (NHS) giving top priority to vaccinating the over-80s, frontline healthcare workers and care home staff and residents.

Britain gave emergency use approval for the vaccine developed by Pfizer and BioNTech last week – jumping ahead in the global race to begin the most crucial mass inoculation programme in history.

In total, Britain has ordered 40 million doses – enough to vaccinate 20 million people in the country of 67 million. About 800,000 doses are expected to be available within the first week.

Initial doses that have arrived from Belgium are being stored in secure locations across the country, where they will be quality checked, the health ministry said.

The Pfizer/BioNTech vaccine has onerous storage requirements. It needs to be kept at -70C (-94F) and only lasts five days in a regular fridge. For that reason, the health ministry said the vaccine would first be administered in 50 hospitals. It said it would take a few hours to defrost each vaccine and prepare it for use.
