In its latest travel warning update, the foreign ministry put Bulgaria’s Blagoevgrad, Dobritch and Black Sea tourist hotspot Varna on its list of places where infections were rising rapidly.
Seven places in Romania -- Arges, Bihor, Buzau, Neamt, Ialomita, Mehedinti and Timis -- were also added.
Germany uses the yardstick of 50 new infections per 100,000 residents in the last seven days to determine if a country or region should go on its high-risk list.
It recently added three regions in Spain to the list in a blow to the fellow EU member state.
