Malaria claimed 193 people's lives and infected 56,789 others last year in Bangladesh's southeastern Chittagong hilly region, according to official figures.
However, Local leading newspaper The Independent reported on Thursday that unofficial figures claimed that the death toll and the number of people affected by malaria in the region would be much higher.
This was disclosed at a round table on malaria control held recently in the country's southeastern Rangamati district, about 293 km southeast of capital Dhaka.
The speakers said at the round table, 13 out of total 64 districts of the country are more vulnerable to malaria. Of these, the three hill districts Rangamati, Khagrachari and Bandarban of the Chittagong hilly region are the most vulnerable.
They said the disease is more rampant in the hill districts during the rainy season, which is favorable for mosquito breeding.
Malaria claims hundreds of lives every year in the region, while the deadly disease kills over a million worldwide, they said.
