Hungary is set to begin testing certain essential workers for coronavirus on a regular basis from Friday, Gergely Gulyas, the head of the Prime Minister's Office has said, adding that the staff of social care homes will be the first to be tested. The government last week decided that health-care workers, teachers and staff members of social institutions will be tested on a regular basis, determined by the operative board responsible for handling the epidemic, Gulyas told a regular press briefing on Thursday. Testing will be voluntary, he added, emphasising that no one would be obliged to take the test.
