PARIS More than 215,000 people have signed a petition urging French officials to let more doctors prescribe the anti-malaria drug chloroquine for coronavirus patients, a controversial proposal that has divided health experts worldwide. Support for the treatment has gained ground as doctors try to keep the coronavirus outbreak from overwhelming hospitals, with some saying early use of chloroquine and similar treatments could keep symptoms from worsening to the point that intensive care is needed. The French petition on the Change.org website was launched Friday by a group of doctors including Philippe Douste-Blazy, a cardiologist and former French health minister. On Monday, three of France’s most respected doctors penned an open letter backing chloroquine use despite the absence of randomised and peer-reviewed studies on its efficiency.—APP
