Three Omicron sub-types sweep Bangladesh

The spike in coronavirus infection continues unabated as Bangladesh has spotted three different sub-types of Omicron variant, causing social transmission here.

The International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B) lab detected Omicron in five out of 77 Covid cases in Dhaka last December.

Others were of Delta variant, according to a study done by the country's reputed research entity.

The ICDDR,B lab identified Omicron in 260 (69 per cent) out of 379 samples received from Dhaka city in the first two weeks of this January.

"Complete sequencing analysis of Omicron variants reported from Bangladesh suggests that at least three different sub-types… have been circulating in Dhaka with African, Euro-American, and Asia-Pacific origin."

The study has been disclosed on the ICDDR,B website.

As of January 20, a total of 63 Omicron cases from Bangladesh have been reported to the GISAID database. Fifty-two of them are from Dhaka city, eight from Chattogram and three from Jashore.

ICDDR,B senior scientist Dr Mostafizur Rahman said they spotted three Omicron sub-types-BA1, BA2 and BA3.

"In the coming days, the transmission of Omicron variant will be increasing for sure. The positivity rate could go up to 60 per cent in the next two weeks."

Dr Rahman suggests following the Covid-19 health protocol to stay protected.

Bangladesh recorded 14,828 more new cases and 15 deaths in the last 24 hours until Monday morning, according to Directorate General of Health Services (DGHS).
