The highly contagious new Omicron sub-variant of coronavirus, BF.7, has been detected in the country, Institute of Epidemiology, Disease Control and Research (IEDCR) sources said.
The presence of a new variant was confirmed in the genome sequence reports of one of the four Covid-19 infected Chinese citizens, IEDCR Director Dr Tahmina Shirin told National News Agency of Bangladesh on Sunday (Jan 1).
Four passengers from China tested positive for Covid-19 at Hazrat Shahjalal International Airport recently after the authorities geared up health screening as they fear the spread of a sub-variant of Omicron, the Directorate General of Health Services (DGHS) sources said.
The new variant is capable of infecting many people within a shorter period, it said adding that, the new sub-variant of Omicron is four times higher transmissible and the incubation period is shorter enabling it to infect many people at a time.
