What you need to know about the coronavirus right now

HERE'S what you need to know about the coronavirus right now:

Masks to remain mandatory on London transport

Masks will remain mandatory on London's public transport network after July 19, the city's mayor said on Wednesday, as Prime Minister Boris Johnson's government plans to lift most COVID-19 restrictions from that date in England despite rising cases.

The public will be expected, rather than compelled by law, to wear masks in indoor enclosed spaces across the country from next week, as rules decided upon by the Conservative administration are eased.

Sydney extends lockdown as outbreak nears 900 infections

Australian authorities extended a lockdown in Sydney on Wednesday by at least 14 days, after three weeks of initial restrictions failed to stamp out the biggest outbreak of COVID-19 this year in the country's largest city.

New South Wales state Premier Gladys Berejiklian said restrictions would need to remain in place until at least July 30 after she reported 97 new locally transmitted cases, a slight increase from a day earlier.

The shutdown has now been extended on two occasions and total infections since the first was initially detected in the city's eastern suburbs in mid-June now stand at just under 900. Two deaths have been reported, the first for the country this year.

Singapore says cruise ship returns after suspected case

Singapore's tourism board said on Wednesday a cruise ship operated by Genting Cruise Lines on a so-called cruise to nowhere had returned to the city-state after a 40-year-old passenger was suspected to have contracted COVID-19. "The passenger was identified as a close contact of a confirmed case on land, and was immediately isolated as part of onboard health protocols," the tourism board said in a statement.

It said the passenger tested positive to a Polymerase Chain Reaction (PCR) test onboard and had been conveyed to hospital for further confirmatory testing.

Living with COVID-19: Israel changes strategy

Under what Prime Minister Naftali Bennett calls a policy of "soft suppression", the government wants Israelis to learn to live with the virus - involving the fewest possible restrictions and avoiding a fourth national lockdown that could do further harm to the economy.

As most Israelis in risk groups have now been vaccinated against COVID-19, Bennett is counting on fewer people than before falling seriously ill when infections rise.

The main indicator guiding the move is the number of severe COVID-19 cases in hospital, currently around 45. Implementation will entail monitoring infections, encouraging vaccinations, rapid testing and information campaigns about face masks.

S.Korea tightens COVID-19 curbs across most of country

South Korea on Wednesday tightened social distancing curbs across most of the country to try to combat its worst-ever outbreak of coronavirus after new COVID-19 cases on Tuesday soared past previous daily peaks to 1,615.

Amid growing concerns over the more contagious Delta variant and a stagnating vaccine rollout, the latest daily tally easily surpassed the previous record - last Friday's 1,378.

Cluster infections have spread rapidly around the capital Seoul and neighbouring areas fuelled by the Delta variant, the Korea Disease Control and Prevention Agency (KDCA) said.
