Some 500 medical students and graduate volunteers have applied to help ease the burden on hospital staff treating Covid-19 patients, the deputy head of Hungary's national hospital manager said on Wednesday. The National Hospital Directorate-General on Monday issued a call for medical students and volunteers to assist with the country's response to the third wave of the coronavirus epidemic. "There is now a greater need than ever for committed helpers to support the work of our doctors and nurses," the directorate's appeal said.
