Many areas in South Asia are popular destinations for travelers.
Malaria — Malaria-endemic areas exist in all countries in this region except the Maldives and Sri Lanka. The transmission risk varies considerably within endemic areas, and transmission occurs in many cities within the Indian subcontinent. Country-specific risk areas are as follows:
●Afghanistan – Risk from May through November at altitudes below 2000 meters.
●Bangladesh – Risk throughout the year in 13 of 64 districts, but transmission occurs only in rural areas. The risk is high in Chittagong Hill Tract districts (Bandarban, Rangamati, and Khagrachari), Chittagong district, and Cox Bazaar district, and the risk is low in Hobigonj, Kurigram, Moulvibazar, Mymensingh, Netrakona, Sherpur, Sunamgonj, and Sylhet. There is no risk in Dhaka City.
●Bhutan – Risk exists in the southern belt of seven districts: Chukha, Dagana, Pemagatshel, Samdrup Jongkhar, Samtse, Sarpang, and Zhemgang.
