More than 800,000 physicians across the country signed a letter urging President Donald Trump to keep social distancing practices in place after he said he wants to reopen businesses by Easter.

“Significant COVID-19 transmission continues across the United States, and we need your leadership in supporting science-based recommendations on social distancing that can slow the virus,” the letter, released by the Council of Medical Specialty Societies, said. “Our societies have closely adhered to these measures by moving our staff to fulltime telework and canceling in-person meetings (including annual meetings). These actions have helped to keep physicians and other health professionals in health care facilities, including hospitals, and reduce the risk of spreading COVID-19.”
