Sonamsjid land port authorities have taken additional cautionary measures to prevent the spread of Omicron BF.7, a new sub-variant of Covid-19.

Following the instruction of the Director General of Health Services (DGHS) some additional measures have been taken to prevent the new sub-variant of Covid-19, said Dr. SM Mahmudur Rashid, civil surgeon of Chapainawabganj.

Indian truck drivers and their helpers are being allowed to enter the country through the border after health screening, he added.

Besides, the members of the medical teams are doing their routine works at the port, Rashid said.

Earlier on Sunday, the Directorate General of Health Services (DGHS) issued an alert at airports, land ports and seaports as the new sub-variant BF.7 of Omicron was detected in China and India.

It also asked the authorities concerned to take steps so that people, coming from those countries, go through tests and digital thermal scanner and thermometer are used at the entry points of the country.

Meanwhile, four returnees from China were sent to isolation after they tested positive for Covid-19 at Hazrat Shahjalal International Airport in Dhaka Monday (December 26) afternoon.
