Delta variant found in 93pc samples: Study

CHATTOGRAM: A study revealed that some 93 per cent of Covid-19 patients were infected by the highly contagious Delta variant in Chattogram.

The study was jointly conducted by two teams of researchers from Chittagong Veterinary and Animal Sciences University (CVASU) and Bangladesh Council of Science and Industry Research (BCSIR) with the financial assistance of CVASU Poultry Research and Training Centre (PRTC).

CVASU Vice Chancellor Professor Dr Gautam Buddha Das disclosed the result on Friday.

The study was conducted on 30 Covid-19 patients infected between July 1 and July 19 by collecting their nasopharyngeal swab samples, he said.

The study also found that the Delta variant is equally spread in urban and rural areas in the district while the researchers collected 15 samples from Chattogram city and 15 from different upazilas in the district.

Among the 30 patients, 12 were men and 18 women.

The samples were then sent to the BCSIR lab where two researchers supervised the genome sequencing of the specimens.

The results showed that of the 30 samples, 28 were infected with the delta variant standing at 93 per cent while 14 are from the city and 14 from the upazilas.

The other two were reported to be infected with the Alpha variant (UK) and the Wuhan variant of China.

The study also revealed that 15 people who provided the samples were admitted to different hospitals for treatment after infecting of the virus.

CVASU Professors Dr Paritosh Kumar Biswas, Dr Sharmin Chowdhury, Dr Iftekhar Ahmed Rana, Dr Tridip Das, Dr Pranesh Dutta, Dr Md Sirajul Islam and Dr Tanvir Ahmed Nizami conducted the research while BCSIR Chief Scientific Officer Dr Md Selim Khan and Senior Scientific Officer Dr Md Morshed Hasan Sarkar also participated.

However, another study conducted found that only 2% of the Covid-19 patients were infected with Indian delta variant in Chattogram in June while the number climbed to over 90% in July.

Earlier, the presence of the alpha (UK variants) and the beta (South African variants) was reported in the Chattogram region.

Despite having the presence of the alpha variant in the district its percentage is very low.
