As India has been experiencing a new strain of Covid-19, the government imposed restrictions along the border areas of Bangladesh. According to the World Health Organisation, the Indian variant has already spread to 60 countries across the world.

Bangladeshi citizens currently travelling to India for treatment and having visas with validity for less than 15 days could enter Bangladesh only through Benapole, Akhaura and Burimari after taking permission from Bangladesh diplomatic missions in New Delhi, Kolkata, and Agartala, and with a mandatory Covid-negative certificate.
