Bulgaria’s National Centre for Infectious and Parasitic Diseases (NCIPD) said on April 20 that it has found the Omicron coronavirus strain in each of the 185 samples taken from Covid-19 patients in the country.
The samples had been taken over a period of time ranging from March 10 to March 30 and came from 16 out of Bulgaria’s 28 districts.
As of April 4, four patients in the NCIPD sample group had died, 38 were in hospital, 112 were undergoing home treatment and 31 had recovered.
NCIPD said that the BA.2 subvariant of the Omicron strain was found in 125 cases, or 67.6 per cent of all samples, compared to 68.2 per cent in the previous sample group sequenced by NCIPD, as announced on April 8.
The remaining samples showed evidence of 11 distinct subvariants of the Omicron strain of the virus, including four cases of BA.1, 18 cases of BA.1.1 and 26 cases of BA.2.9 subvariants.
The largest number of samples in the latest group sequenced by NCIPD came from the city of Sofia (42), followed by the districts of Plovdiv (36), Bourgas (27), Veliko Turnovo (17), Varna (14) and Pleven (12).
