For the moment, there is no need to impose a curfew in Sofia, Director of Regional Health Inspectorate - Sofia Dr. Pancho Penchev told BNT after it became clear yesterday that a tightening of measures is being considered due to the spike in infections and the mounting pressure on the Sofia hospitals.
"This is Act One," he says, "No one knows how it is really going to play out."
Most of those who have returned in the wake of COVID-19 and who work in manual labour and agriculture will probably go abroad again, if they have not done so already, Boyadzhiev says. However, he adds, COVID is accelerating trends that were already present in Bulgaria before the pandemic.
