Institute of Epidemiology Disease Control and Research (IEDCR) has said that it has found the Indian (Delta) variant of coronavirus in the samples of 80 per cent COVID-19 infected patients in Bangladesh after sequencing their genomes.
The findings of the joint study by IEDCR and Institute for Developing Science and Health Initiatives (IDSHI) has been published in a new report.
According to the report, the IEDCR found 40, out of 50, [which is 80 per cent] COVID patients were infected with the Indian variant of the deadly disease.
The recent IEDCR survey found evidence of community transmission of the variant and also detected an unknown variant in the country.
Among the 40 patients, eight were tested positive after returning from India, while 18 others came in contact with overseas returnees although they did not travel abroad.
Of the genome sequenced samples, 16 were collected from Covid patients in Chapainawabganj. The Delta varint has been found in 15 samples.
All seven samples collected from Gopalganj contained Indian variant, while all three samples from Khulna city were also infected by Indian variant.
Two, out of the four samples, collected from the capital Dhaka, contained the Indian variant after genome sequencing, said the IEDCR report.
Besides, seven Chapainawabganj residents who travelled to Dhaka’s Nababganj upazila were also found infected with the Indian variant.
Three more Indian returnees, who were also found infected with the Delta variant, are currently under treatment in Chuadanga and Khulna.
Of the rest tested samples, eight were infected with the South African variant, also known as the ‘Beta’ variant.
One of the two rest variants remained unidentified, said IEDCR.
As a consequence, it is clear that the Indian variant is being transmitted at the community level inside the country, the IEDCR further said.
