U.S. urges vaccinated Americans to wear masks indoors in many places
Americans fully vaccinated against Covid-19 should go back to wearing masks in indoor public places in regions where the coronavirus is spreading rapidly, U.S. health authorities said.
U.S. coronavirus cases have been rising due to the highly contagious Delta variant, which emerged in India but has quickly spread and now accounts for more than 80% of U.S. coronavirus cases.
U.S. President Joe Biden said that increased vaccination and mask wearing would help the United States avoid the pandemic lockdowns, shutdowns and school closures the country faced in 2020.
Biden is meanwhile considering whether to require U.S. federal employees to be vaccinated.
UK's Johnson wants U.S. travellers back as restrictions set to ease
British Prime Minister Boris Johnson wants U.S. citizens to come to England "freely" and is discussing a travel corridor with the United States, LBC radio said on Wednesday, before an expected easing of Covid-19 restrictions for visitors from abroad.

Australia's biggest city, Sydney, extended a lockdown by four weeks on Wednesday after an already protracted stay-at-home order failed to douse a Covid-19 outbreak, with authorities warning of tougher policing to stamp out non-compliance.
Far from a planned exit from lockdown in three days, the city of 5 million people and neighbouring regional centres spanning 200 km (120 miles) of coastline were told to stay home until Aug. 28 following persistently high case numbers since a flare-up of the virulent Delta variant began last month.
