Twitter has removed a tweet by Scott Atlas, a controversial scientist who has Donald Trump’s ear, in which he wrongly stated that masks fail to protect against coronavirus.

The Washington Post, meanwhile, reported that Atlas has scattered discord inside the White House, so infuriating Deborah Birx, the coronavirus response coordinator, that she complained to Vice-President Mike Pence, calling for Atlas to be removed.

Intensive care units (ICUs) at hospitals treating COVID-19 patients should do away with air-conditioning to limit the risk of infecting doctors, according to a study by the Indian Institute of Science in Bengaluru.

Reuters reports:

Frontline health workers around the world have borne the brunt of the coronavirus crisis. More than 500 doctors have died from COVID-19 in India – the world’s second-worst hit nation – as infections near 8 million, straining the country’s weak and underfunded public health system.

“The recirculation of the air by the centralized air-conditioning systems is what has led to the significant infection of our committed medical fraternity and has also led to deaths of doctors and nurses,” the study by the Indian Institute of Science in Bengaluru, considered one of the country’s best science universities, said.
