Around 98 percent coronavirus infected patients of the country have been infected with the highly contagious delta or Indian variant of the virus, said a study.

Bangabandhu Sheikh Mujib Medical University (BSMMU) carried out the research on patients aged between nine months and 90 years -- mostly between 30 and 39.

Vice-chancellor of BSMMU Prof Dr Sharfuddin Ahmed, also supervisor of Genome Sequencing Research Project, disclosed the study report of Covid-19 genome sequencing to journalists at the university on Thursday morning.

The research was conducted through the representative sampling of 300 Covid-19 patients from all the divisions, between June 30 and July 30. Of them, 53 percent were male.

According to the first-month findings of the coronavirus genome sequencing, the mortality rate is higher among patients with comorbidities, including diabetes, cancer, respiratory problems and lung disease.

Moreover, there is high risk of death if Covid-19 patients above 60 years are infected a second time, the research findings added.

After genome sequencing of collected swab samples, the study found that 98 percent were delta variant, also known as B.1.617.2,  and one percent was beta variant or South African variant (B.1.351) and the rest was Nigerian variant (B.1.525). According to the research, the national database, as well as a global network of Covid-19 database, can be made after analysing the sample sequencing of at least 3,000 patients.

The BSMMU vice-chancellor said delta is a highly contagious variant of the coronavirus.

“You need to get vaccinated to get protection from this virus variant. The advantage of vaccination is that if anyone is infected with the variant after taking vaccine then the complications will be less. This will reduce the death rate. However, you have to wear a mask for overall protection,” he said.

Chairman of anatomy department of BSMMU Laila Anjuman Banu, also professor of Genetics and Molecular Biology of the university was the lead researcher and Md Sayedur Rahman, chairman of Department of Pharmacology, and Professor Dr AKM Mosharraf Hossain, pro-vice-chancellor (academic) of the university, were co researchers. A total of 14 researchers were involved in the study.
