What you need to know about the coronavirus today

The ozone effect
Japanese researchers said low concentrations of ozone can neutralize coronavirus particles, potentially providing a way for hospitals to disinfect examination rooms and waiting areas.
Scientists at Fujita Health University told a news conference they had proven that ozone gas in concentrations of 0.05 to 0.1 parts per million, levels considered harmless to humans, could kill the virus.
The experiment used an ozone generator in a sealed chamber with a sample of coronavirus. The potency of the virus declined by more than 90% when subjected to low level ozone for 10 hours.

Authorities in Marseille said that bars and restaurants would have shorter opening times, and they also broadened mandatory mask-wearing in the southern port city between Aug. 26 and Sept. 30.

Trainee doctors have been staging ongoing walkouts, and thousands of additional doctors were due to stage a three-day strike.
Lessons from India’s Silicon Valley
The early COVID-19 response in Bengaluru, dubbed India’s Silicon Valley for its tech firms and startups, was lauded by India’s government as a model, for its use of health surveys combined with efforts to tap tech expertise and cutting-edge software to analyse the spread of the disease. But after India eased a nationwide lockdown in early June, officials say tens of thousands of travelers streamed in from Maharashtra and Tamil Nadu, many unwittingly bringing the virus. The neighbouring states have been the two worst hit by COVID-19 in India. “We didn’t look at the inbound travellers as a major source of infections,” said one official involved in Bengaluru’s response. “We never anticipated that many people would come.”
