Bulgaria’s National Centre for Infectious and Parasitic Diseases (NCIPD) said that it has completed the sequencing of 552 samples taken from Covid-19 patients in the country, finding 548 instances of the Delta variant.
The samples had been taken over a period of time ranging from August 15 to September 2 and came from 26 out of Bulgaria’s 28 districts. These included three samples taken from foreign nationals, although NCIPD did not clarify if the people tested were permanent residents, tourists or in transit.
As of September 1-3, 28 patients who had been shown by the sequencing to have had the Delta variant had died, 85 were in hospital, 401 were undergoing home treatment and 34 had recovered.
The other four samples were a case of the Alpha variant and three cases of coronavirus strain C.36.3.1, which the World Health Organisation currently designates as an “alert for further monitoring”, below the status of “variant of interest” or “variant of concern”. The Delta strain is one of four current “variants of concern”, according to the WHO designation.
The patient with the Alpha variant had died and the three patients with the C.36.3.1 strain were undergoing treatment at home as of September 1-3, NCIPD said.
The largest number of Delta variant samples came from the districts of Bourgas (72), Varna (69), Turgovishte (61), Stara Zagora (51) and the city of Sofia (51).
Of the three samples from foreign nationals, two were from the district of Varna and one from the district of Sofia. All three samples had the Delta variant.
