Noma (cancrum oris) is a serious gangrenous disease of the mouth and face, mainly affecting children aged 2 to 6 years in sub-Saharan Africa.
Despite substantial knowledge gaps, it is reported to be linked with malnutrition, poor oral hygiene, im...munosuppression, and living in extreme poverty situations.
This course addresses epidemiology, pathogenesis, clinical features, diagnosis, treatment, and public health considerations, including the human rights perspective of noma.

Dracunculiasis (Guinea worm disease), caused by the parasite Dracunculus medinensis, is traditionally acquired by drinking water containing copepods (water fleas) infected with D. medinensis larvae, but in recent years also appears increasingly to b...e transmitted by eating fish or other aquatic animals. The worm typically emerges through the skin on a lower limb of the host 1 year after infection, causing pain and disability.

Onchocerciasis causes skin and eye disease, visual impairment and neurological problems. It is mostly found in Africa, but also in Latin America and Yemen. The common name, ‘river blindness,’ gives a good indication where the ...ute-to-highlight medbox">disease can be found: the vector of the parasite, a small black fly of the Simulium species, breeds in rivers where there is turbulence in the water, such as rapids, or where the flow is disturbed by overhanging vegetation.

Rabies is a fatal zoonotic disease most often transmitted to people via bites from infected dogs. This course provides a general introduction to rabies, and the One Health approach currently taken to prevent it. It consists of seven video-lectures, ...demonstration videos, and lessons learnt from people who work at the frontline of rabies elimination programmes around the world. It targets both a general audience and those who would like to learn more about rabies and the pathway to eliminating this disease – like prospective and current public health and animal health practitioners in rabies endemic countries.

Leishmaniasis is an infectious disease caused by protozoan parasites of the genus, Leishmania. Protozoa are microscopic, single-celled organisms. The parasites that cause the disease are transmitted... to people through the bites of certain species of infected sand flies.

Schistosomiasis is widely recognized as a disease that is socially determined. An understanding of the social and behavioural factors linked to disease transmission and control should play a vital r...ole in designing policies and strategies for schistosomiasis prevention and control. To this must be added the awareness that schistosomiasis is also a disease of poverty. It still survives in poverty-stricken, remote areas where there is little or no safe water or sanitation, and health care is scarce or non-existent. For a variety of complex reasons, many of which are addressed in this book, the disease is particularly prevalent in sub-Saharan Africa, and persists in certain areas of rural China. This concern for human behaviour in an environment of poverty echoes the concerns of the new research priority for “diseases of poverty” identified by the Special Programme for Research & Training in Tropical Diseases.

Schistosomiasis is an acute and chronic parasitic disease caused by blood flukes (trematode
worms) of the genus Schistosoma. At least 249 million people required preventive treatment in

Rabies is a vaccine-preventable viral disease which occurs in more than 150 countries and territories. Dogs are the source of the vast majority of human rabies deaths, contributing up to 99% of all rabies transmissions to humans.
The previous report of the WHO Expert Committee on this disease
followed a meeting in 1995. Intensive, coordinated efforts against HAT during
the intervening 18 years have resulted in a decrease in incidence to a point at
which elimination is ...considered feasible. This report provides information about
new diagnostic approaches, new therapeutic regimens and better understanding
of the distribution of the disease with high-quality mapping. The roles of human
and animal reservoirs and the tsetse fly vectors that transmit the parasites are
emphasized. The new information has formed the basis for an integrated strategy
with which it is hoped that elimination of HAT will be achieved. The report also
contains recommendations on the approaches that will lead to elimination of the
disease.

Foodborne trematodes are a group of diseases that include the parasites Clonorchis, Opisthorchis, Fasciola and Paragonimus. These parasitic flukes have a complex life cycle invo...lving diverse definitive hosts and one or two intermediate hosts. Foodborne trematodes cause infection in humans via the consumption of contaminated food (raw fish, crustaceans or vegetables). Infection can result in severe liver and lung disease and together these diseases are estimated to cause 2 million life years lost to disability and death worldwide every year.

The Chagas disease is frequently referred to as the effects that the parasite Trypanosoma cruzi (T. cruzi) has on people’s health. However, from our perspective, Chagas is much more than that: it is a comple...x socioenvironmental health problem in which elements of different nature converge and interact. The biomedical and epidemiological aspects, which are most frequently addressed, are only a piece of the puzzle that needs to be complete in order to understand Chagas in all its complexity. Social, environmental, economic, political, cultural, and educational elements turn out to be essential in comprehending the magnitude of the problem without prejudice or stigmatizations.

Leishmaniasis A group of diseases, caused by the Leishmania parasites and transmitted by the sandfly
Dracunculiasis, also known as Guinea-worm disease is a parasitic disease caused by the nematode Dracunculus medinensis. The infection is transmitted to humans by drinking water contaminated with the... small crustacean copepods (Cyclops) which contain the larvae of D. medinensis. Humans are the principal definitive host and Cyclops being the intermediate host. The disease is endemic to the rural and poorer areas of the world and is most common in African countries like Chad, South Sudan, Ethiopia, and Mali. Efforts are underway towards global eradication of this disease. Due to its rarity in developed countries, this activity describes the interprofessional team's role in the assessment and treatment of patients with this condition.

Mycetoma is a chronic, progressively destructive morbid inflammatory disease usually of the foot but any part of the body can be affected. Infection is most probably acquired by traumatic inoculation of certain fungi or bacteria into the subcutan...eous tissue. Mycetoma was described in the modern literature in 1694 but was first reported in the mid-19th century in the Indian town of Madura, and hence was initially called Madura foot.
