Ninety-eight percent of the Covid patients recently detected in Bangladesh are of the highly contagious Delta variant while just one percent are of South African Beta variant ones, says a BSMMU survey.   Vice-Chancellor of the BSMMU (Bangabandhu Sheikh Mujib Medical University) Prof M Sharfuddin Ahmed, also the supervisor of Genome sequencing research project, revealed the survey report on Thursday after scrutinizing 300 samples collected from June 29 to July 30.   Read: Why might COVID-19 vaccine boosters be necessary? The aim of the research is to unveil the character of genome, type of mutation and discover the inter-relations of with global Covid-19 genome as well as preparing a database of Bangladesh Covid-19 genome.   This is the result of the first month of the BSMMU research and its updated result will be revealed in the months to follow. The genome sequencing was conducted through next generation sequencing after collecting the nasopharyngeal swab samples of Covid-19 positive patients.
