BANGKOK--South Koreans will be required to wear masks when using public transportation and taxis nationwide starting Tuesday as authorities look for more ways to slow the spread of the coronavirus as people increase their public activities.

Health Ministry official Yoon Taeho on Monday said masks will also be required on all domestic and international flights from Wednesday. From June, owners of “high-risk” facilities such as bars, clubs, gyms, karaoke rooms and concert halls will be required to use smartphone QR codes to register customers so they can be tracked down more easily when infections occur.

South Korea was reporting 500 new cases per day in early March before it largely stabilized its outbreak with aggressive tracking and testing. But infections have been rising slightly since early May, with more people going out during warmer weather and eased social distancing guidelines, causing concern in a country that has just started to reopen schools.

“Until treatments and vaccines are developed, we will never know when the COVID-19 crisis could end, and until then we will have to learn how to live with COVID-19,” Yoon said.

It will be up to bus drivers and subway station workers to enforce masks on public transportation, while taxi drivers will be allowed to refuse passengers who aren’t wearing masks.

South Korea has reported 11,206 COVID-19 cases, including 267 fatalities.

WUHAN CONDUCTS MASSIVE TESTING: The Chinese city of Wuhan has conducted more than 6.5 million coronavirus tests over a 10-day period in a bid to test all its 11 million residents, state media said Monday. The city’s health commission, in a post on its website, asked anyone who hasn’t been tested to come forward by the end of Tuesday. One new COVID-19 case has been confirmed since the 10-day campaign started, and some people with no symptoms also tested positive. More than 3 million people had been tested prior to the campaign, the official Xinhua News Agency said. Wuhan, where the global pandemic is believed to have started late last year, was by far the city hit hardest in China.

ABE SAYS VACCINE KEY TO OLYMPICS: Prime Minister Shinzo Abe on Monday said development of effective drugs and vaccines is essential for holding the Tokyo Olympics next year. He said it isn't enough for coronavirus infections to be under control in Japan if outbreaks continue elsewhere since the Olympics is an international event. “I’m anxious to bring together wisdom from around the world to speed up development of vaccines and effective medicines,” Abe said. Japan hopes to host the Tokyo Games “in a complete form” to demonstrate human victory over the coronavirus, he said. In late March, Japan and the International Olympic Committee agreed to postpone the games by one year to July 2021. Experts say developing an effective and safe vaccine by then is difficult.

INDIA FLIGHTS BACK IN AIR: Domestic airline travel partially resumed in India, which is easing its virus lockdown despite adding more than 6,000 new infections per day. At New Delhi’s airport, passengers in masks or full protective suits stood in long lines to show identification and boarding passes to security personnel standing behind plastic partitions. Ticket machines have been shifted outside, where airport workers sanitized baggage. Commercial flight traffic returned across India except for the states of Andhra Pradesh and West Bengal. India’s Supreme Court has ordered social distancing norms in airports and in flight, forcing airlines to keep middle seats open.

MORE AUSTRALIANS BACK IN SCHOOL: Students in two more Australian states returned to school full-time as numbers of COVID-19 patients in hospitals across the country fall. New South Wales and Queensland states joined the less populous Western Australia and South Australia states and the Northern Territory in resuming face-to-face learning instead of studying from home online. Queensland Premier Annastacia Palaszczuk said students and teachers should stay home if they are sick, noting “We’re not out of the woods yet." New South Wales Premier Gladys Berejiklian said school absences appeared to be higher than normal. Australia's remaining jurisdictions plan to send students back to school in stages through early June.

NEW ZEALAND TO ALLOW CROWDS: New Zealand plans to further loosen its coronavirus restrictions by increasing the maximum size of gatherings from 10 people to 100. Prime Minister Jacinda Ardern said the change would take effect midday Friday. The timing is designed, in part, to allow religious services to proceed that day and over the weekend. New Zealand has reported just one new case of coronavirus over the past week. Ardern attributed that success to a strict early lockdown and people’s ongoing vigilance. “We are still in a global pandemic,” Ardern said. “Cases continue to grow overseas, and we still do have people coming home. But for the most part, many aspects of life can and should feel much more normal.”
