Neglected diseases

What are neglected diseases?

These medical issues disproportionally affect people in the world’s least-developed countries and there are few tools available with which to diagnose and treat.

Neglected diseases include tropical diseases, such as kala azar (visceral leishmaniasis) and sleeping sickness (human African trypanosomiasis), plus issues such as snakebite envenoming, but also Chagas, noma, cutaneous leishmaniasis, and others.

These diseases are considered “neglected, because – although they are usually life-threatening and claim thousands of lives every year – the pharmaceutical and diagnostic industries ignore the development of vaccines, diagnostic tools and drugs to tackle them.

Neglect can be overcome

Neglected tropical diseases have one thing in common: They are found in poor countries. This is because pharmaceutical companies aren't interested in investing money in medicine that they won't make a profit on.
