Yaws is a disfiguring non-venereal disease caused by infection with the spirochaete. Treponema pallidum subspecies pertenue which is closely related to the causative agent of syphilis and those of the other endemic treponematoses, bejel and pinta. The disease is endemic in certain areas of the

World Health Organization (WHO) African, South-East Asia and Western Pacific regions. Of the neglected tropical diseases identified for elimination and eradication, yaws is one of two diseases targeted for eradication. In 1949, the Second World Health Assembly adopted resolution WHA2.36, which addresses yaws, bejel and pinta as major public health problems that need attention.

In May the Sixty-sixth World Health Assembly adopted resolution WHA66.12 (1) on 17 neglected tropical diseases (NTDs). Among other measures, the resolution urges Member States to:
• ensure count

ry ownership of prevention, control, elimination and eradication programmes;
• expand and implement interventions and advocate for predictable, long-term international financing for activities related to control and capacity strengthening;
• integrate control programmes into primary health-care services and existing programmes;
• ensure optimal programme management and implementation;
• achieve and maintain universal access to interventions and reach the targets of the roadmap.

There are 3 main forms of leishmaniases: visceral (the most serious form because it is almost always fatal without treatment), cutaneous (the most common, usually causing skin ulcers), and mucocutaneous (affecting mouth, nose and throat).
Leishmaniasis is caused by protozoan parasites which are tra

nsmitted by the bite of infected female phlebotomine sandflies.
The disease affects some of the world’s poorest people and is associated with malnutrition, population displacement, poor housing, a weak immune system and lack of financial resources.
An estimated 700 000 to 1 million new cases occur annually.
Only a small fraction of those infected by parasites causing leishmaniasis will eventually develop the disease.

Course information
Yaws is targeted for eradication by WHO in the 2021-2030 NTD Roadmap. It is therefore crucial to know how to identify cases, design and implement activities to eradicate the disease at the community level.
In the context of integration of skin NTDs it is vital to learn to recogn

ize a disease targeted for eradication. At the individual level yaws lesions may mimic other skin diseases. At the community level, it is key to know how to design and implement the total community treatment strategy and monitor its impact. This course aims at providing health workers with the basic knowledge to understand the epidemiology, diagnosis, treatment, impact, eradication strategy and reporting of yaws.

Onchocerciasis used to be an important public health problem in Africa, with over 37 million people infected and millions suffering from debilitating skin disease, terrible itching, impaired vision and

Human echinococcosis is a zoonotic disease (a disease that is transmitted to humans from animals) that is caused by parasites, namely tapeworms of the genus Echinococcus.
An interregional meeting on leishmaniasis among neighbouring endemic
countries in the Eastern Mediterranean, African and European regions was organized by the World Health

Organization (WHO) Regional Office for the Eastern
Mediterranean in Amman, Jordan, from 23 to 25 September 2018. The meeting was attended by representatives from the health ministries of Albania, Georgia, Greece, Iran (Islamic Republic of), Iraq, Jordan, Lebanon, Morocco, Pakistan, Saudi Arabia, Sudan, Syrian Arab Republic and Tunisia. Representatives from Afghanistan, Algeria and Libya were unable to attend. The Secretariat comprised staff from WHO headquarters, WHO regional offices in the Eastern Mediterranean, Africa and Europe, WHO country offices in Iraq, Pakistan, Syrian Arab Republic and Yemen, and WHO temporary advisors from Spain and Tunisia.

Fascioliasis is caused by two species of parasitic flatworms or trematodes that mainly affect the liver. It belongs to the group of foodborne trematode infections and is a zoonosis, meaning an animal infection that may be transmitted to humans.
Foodborne trematode infections cause 2 million life years lost to disability and death worldwide every year.
People become infected by eating raw fish, crustaceans or vegetables that harbour the parasite larvae.
Foodborne trematodiases are most prevalent in East Asia and South America.
Foodborne
...
trematode infections result in severe liver and lung disease.
Safe and efficacious medicines are available to prevent and treat foodborne trematodiases.
Prevention and management of food-borne trematodes requires cross-sectoral collaboration on the human-animal and ecosystems interface.

Human scabies is a parasitic infestation caused by Sarcoptes scabiei var hominis. The microscopic mite burrows into the skin and lays eggs, eventually triggering a host immune response that leads to intense itching and rash. Scabies infestation may be complicated by bacterial infection, leading to t
