Diseases

Six of the infections caused by NTDs (notated by asterisk, listed above) can be controlled or even eliminated through mass administration of safe and effective medicines (mass drug administration, MDA), or other, effective interventions. These diseases are known as targeted or "tool ready" NTDs. Along with MDA and interventions, efforts to control the vectors (e.g. mosquitoes, black flies) that transmit these diseases and to improve basic water, sanitation, and hygiene, are highly effective strategies against these NTDs.

MDA-based programs are considered one of the best buys in public health – with a low cost of about 10-50 cents per person per year – with the added benefit of helping treat or prevent several different diseases. These programs have benefited from donations of medications by major pharmaceutical companies including Eisai, GlaxoSmithKline, Johnson & Johnson, Merck and Co., Inc, and Pfizer, support from the United States Government (led by the United States Agency of International Development), the Bill and Melinda Gates Foundation, the Japan International Cooperation Agency, and the U.K. Department of International Development, among others.

Who is Most Affected?

Seven of the most common NTDs can be found in a number of countries, primarily in low and middle income countries of Africa, Asia, and Latin America. NTDs affect the world’s poorest people and are especially common in tropical areas, where people have little access to clean water or proper ways to dispose of human waste. Women and children who live in unsanitary environments face the biggest threat of NTDs. The interactive map below illustrates the geographic distribution of the seven most common NTDs.
