Detailed description

The diseases, often caused by worms and single-cell organisms, are usually chronic and reduce the productivity of those affected, trapping them in a cycle of poverty and disease. The WHO currently lists 21 diseases (as of January 2024), including leprosy, dengue fever, and sleeping sickness. The WHO estimates that approximately 1.7 billion people worldwide are affected by these diseases and another two billion are at risk. They are referred to as "neglected" because they receive little attention and research funding, despite their prevalence and seriousness.
