Covid-19 in Bulgaria: Delta variant found in all 554 sequenced samples – NCIPD

Bulgaria’s National Centre for Infectious and Parasitic Diseases (NCIPD) said on November 25 that it has completed the sequencing of 554 samples taken from Covid-19 patients in the country, all of them showing the Delta variant.

The samples had been taken over a period of time ranging from October 13 to November 11 and came from 23 out of Bulgaria’s 28 districts.

As of November 15, 20 patients in the NCIPD sample group had died, 97 were in hospital, 428 were undergoing home treatment and nine had recovered.

NCIPD said that 117 cases it sequenced showed the Delta strain of the virus, collectively designated B.1.617.2 by the World Health Organisation.

The other cases were attributed to separate individual lineages of that variant, with the most numerous being AY.43 (107), AY.9.2 (74), AY.4 (56), AY.4.4 (41), AY.98 (36), AY.4.2 and AY.9 (20 each). Twenty other subvariants were sequenced in the remaining 83 samples.

The largest number of samples came from the city of Sofia (96), followed by the districts of Bourgas (85), Rousse (53), Plovdiv (51), Turgovishte (47) and Stara Zagora (44).
