Neglected tropical diseases (NTDs)

Neglected tropical diseases (NTDs), like dengue fever, bodily fluid disease, trachoma, and kala azar, are known as "neglected," as a result of they typically afflict the world's poor and traditionally haven't received the maximum amount attention as different diseases. NTDs tend to thrive in developing regions of the globe, wherever water quality, sanitation, and access to health care are substandard. However, a number of these diseases are found in areas of the us with high rates of poorness.

NTDs are found in many countries in continent, Asia, and geographic region. NTDs are particularly common in tropical areas wherever individuals don't have access to wash water or safe ways that to eliminate excretion.

Information on diseases enclosed within the UN agency portfolio of NTDs is out there at icon

See below for additional data on designated neglected tropical diseases:

☑️Buruli lesion

☑️Chagas illness


☑️Dengue Fever

☑️Dracunculiasis (Guinea Worm Disease)



Human African Trypanosomiasis (African Sleeping Sickness)


☑️Leprosy (Hansen’s Disease)

☑️Lymphatic disease





☑️Soil-transmitted Helminths (STH) (Ascaris, Hookworm, and Whipworm)


The following six NTDs is controlled or perhaps eliminated through mass administration of safe and effective medicines or different, effective interventions:

☑️Dracunculiasis (Guinea Worm Disease)

☑️Lymphatic disease



☑️Soil-transmitted Helminths (STH) (i.e., Ascaris, Hookworm, and Whipworm)


☑️Controlling the vectors (e.g., mosquitoes, black flies) that transmit these diseases and rising basic water, sanitation, and hygiene are extremely effective ways against these NTDs.

Why is that the Study of Neglected Tropical Diseases a Priority for NIAID?

Neglected tropical diseases, take an amazing toll on world health. the globe Health Organization estimates that quite one billion individuals — some sixth of the world's population — suffer from a minimum of one NTD. whereas NTDs seldom result in death, they will cause vital incapacity that persists for a life, including fatigue, blindness, and disfigurement. Sufferers miss college, are unable to figure, or are too embarrassed to hunt medical aid. By decreasing quality of life and opportunities to succeed, NTD will reinforce the cycle of poorness among the world's underprivileged populations.

How Is NIAID Addressing This crucial Topic?

NIAID encompasses a strong program of analysis dedicated to higher understanding, preventing, and treating NTDs. Studies conducted and supported by NIAID have light-emitting diode to special new discoveries regarding the microbes that cause NTDs, the identification of targets for potential new medication and vaccines, and therefore the development of ways for dominant the organisms that transmit NTD-causing agents to humans. 

The infectious agents accountable include:

☑️viruses (rabies and dengue)

☑️bacteria (leprosy, yaws, eye disease and Buruli ulcer)

☑️protozoa (leishmaniasis and trypanosomiasis)

☑️helminth parasites (schistosomiasis, bodily fluid disease, river blindness, enteric worms and Guinea worm).

Transmission is equally numerous and may manifest itself via:

☑️flies, fomites (e.g. skin cells, hair, covering or bedding) and fingers (trachoma)

☑️mosquitoes (dengue fever and filariasis)

☑️tsetse flies (sleeping sickness)

☑️sandflies (leishmaniasis)

☑️blackflies (onchocerciasis)

☑️snails, that unleash infective larvae into water to penetrate human skin (e.g schistosomiasis)

☑️the faeco-oral route (e.g. soil-transmitted helminths-see page 29) or via food product.

☑️NTDs will cause sightlessness (onchocerciasis and trachoma), deformity and unfitness, disfigurement, cancers, and medical specialty issues.


Programmes to eliminate and management NTDs address problems with equity (equal access to health care) and are interventions that directly profit the poor. The drug treatments are effective and loosely safe once correct policies are followed (see).

Mass drug administration programmes that scale back morbidity, mortality and transmission – resulting in elimination of a number of the world's most distressing diseases -should be considered such as world immunization once viewed from a strategic perspective. would like} proved  that it's potential to deliver free medication to the poorest in need at unit prices that even a number of the poorest countries will afford, and have already afforded. we have a tendency to should concern this undefeated intervention to be created obtainable to everybody UN agency wants treatment. If this comparatively straightforward form of intervention – free medication, no would like for a chilly chain – can't be replicated and scaled up to succeed in everybody UN agency wants treatment, worldwide, there's very little hope that we are able to build a major impact in different priority areas, like maternal and kid health, or vaccinations.
