Bandarban is the most remote district in terms of its geographic pattern, given its vast forest, hills and peaks. To make access more difficult, the area has very limited roadways and other modern communications. The majority of population is from 13 tribal groups of different ethnicities. The language and customs are distinctive from the mainstream population of Bangladesh. Although the size of the population is less than 300,000 in this district, it seriously lacks in formal health facilities and healthcare providers.
The community-‐led Kollyani clinic and the health care program have been contributing to national health by providing primary health care in the remote villages and to those who are marginalized.
