2021-08-19 17:24:51 Neglected Tropical Diseases (NTD)

According to the WHO, Neglected Tropical Diseases (NTD) are common infections found in marginalized communities in developing regions of Africa, Asia and the Americas.

Neglected Tropical Diseases (NTD) are caused by a variety of pathogens such as viruses, bacteria, protozoa and parasitic worms.

Snakebites, pruritus, Yaws, Trachoma, Kala-azar (Leishmaniasis), Chagas etc. are some examples of 'Neglected Tropical Diseases' (NTDs).

NTDs affect more than a billion people globally.

These diseases are preventable and treatable. However, their intricate interrelationships with poverty and ecological systems continue to cause devastating health, social and economic consequences.”
