Trachoma is the leading infectious cause of blindness (2). It is characterized by repeated
conjunctival infection with particular strains of Chlamydia trachomatis. This scars the conjunctivae and,
in some cases, leads to trichiasis with or without entropion. The abrasive action of eyelashes can

Un comité OMS d’experts sur la trypanosomiase humaine africaine (THA) : lutte et surveillance, s’est réuni à Genève (Suisse), du 22 au 26 avril 2013. Le Dr H. Nakatani, sous-directeur général pour le VIH/SIDA, la tuberculose, le paludisme et les maladies tropicales négligées, a ouvert la... réunion au nom du Dr M. Chan, directeur-général de l’OMS.
La THA est une maladie qui afflige les populations rurales de l’Afrique, là où prolifère la mouche tsé-tsé (ou glossine), vecteur des trypanosomes qui en sont la cause. On distingue deux formes de THA : la forme à T. b. gambiense ou forme gambienne, endémique en Afrique de l’Ouest et en Afrique centrale et qui
représente actuellement 95 % des cas, et la forme à T. b. rhodesiense ou forme rhodésienne, endémique en Afrique de l’Est et en Afrique australe, à laquelle sont dus les 5 % restants.

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
blindness. But the epidemiological situation has improved dramatically over the last two decades.... Community directed treatment with ivermectin has effectively brought the disease under control in most endemic areas where onchocerciasis is no longer a public health risk.

Chromoblastomycosis (CBM), represents one of the primary implantation mycoses caused by melanized fungi widely found in nature. It is characterized as a Neglected Tropical Disease (NTD) and mainly affects populations living in poverty with significant morbidity, including stigma and discrimination.
Mycetoma is a chronic infectious disease of the subcutaneous tissue with a high morbidity. This disease has been reported from countries between 30°N and 15°S since 1840 but the exact burden of disease is not known. It is currently unknown what the incidence, prevalence and the number of reported ...cases per year per country is. In order to estimate what the global burden of mycetoma is, a meta-analysis was performed. In total 50 studies were included, which resulted in a total of 8763 mycetoma cases. Most cases were found in men between 11 and 40 years of age. The foot was most commonly affected.

TDR (Tropical Disease Research) Annual Report 2018
Taeniasis and cysticercosis caused by the parasite T. solium affect vulnerable populations,
mainly in Latin America, sub-Saharan Africa and Asia, where pigs (the intermediate host) roam
free and poor sanitation allows pigs access to human faeces.
The major neglected tropical diseases, Taenia solium taeniosis/cysticercosis and schistosomiasis caused by Schistosoma mansoni or S. haematobium are presumed to be widely distributed in Africa. Taenia solium taeniosis/ cysticercosis has been reported as an emerging disease in different regions of Af...rica [1, 2], but currently the exact distribution remains unclear. Reported prevalences of T. solium taeniosis and cysticercosis in African countries are not extensive and are further complicated by the lack of ‘gold standard’ tests for diagnosis.

Rabies is entirely preventable, and vaccines, medicines, tools and technologies have long been available to prevent people from dying of dog-mediated rabies. Nevertheless, rabies still kills about 60 000 people a year, of whom over 40% are children under 15, mainly in rural areas of economically dis...advantaged countries in Africa and Asia. Of all human cases, up to 99% are acquired from the bite of an infected dog.

Promoting health and preventing disease is a critical component of the effort required to achieve Universal Health Coverage (UHC). to date, efforts to achieve UHC have focused mostly on strengthening health systems and their capacities to provide curative care. However, experience from the COVID-19 ...pandemic has reaffirmed the need for resilient health systems, emphasizing primary health care, including preventive and promotive health and well-being.
Emerging from the eye of the storm as the global health lead agency during the pandemic, WHO is equipped with the required insights and actions for a holistic approach to “building back fairer and better” after COVID-19.
The Healthier Populations (UHP) Cluster in the African Region is designed to support Pillar 3 of WHO’s 13th Global Programme of Work (GPW13) which aims to make 1 billion people healthier by reducing health inequities, preventing diseases and injuries, addressing health determinants, and promoting partnerships for collaborative actions amongst all stakeholders.

Report of a global meeting on yaws eradication surveillance, monitoring and evaluation: Geneva, 29–30 January 2018. World Health Organization.
Lymphatic filariasis (LF) is an avoidable, debilitating, disfiguring disease caused by infection with the filarial parasites Wuchereria bancrofti, Brugia malayi and B. timori. Globally, 51.4 million people are
estimated to be infected. Lymphoedema and hydrocoele are the visible, chronic clinical co...nsequences of the lymphatic vessel impairment caused by infection with these parasites. Mosquitos in the genera Culex, Anopheles, Mansonia and Aedes transmit the parasites from person to person. 2020 marked the 20th year since WHO established the Global Programme to Eliminate Lymphatic Filariasis (GPELF) which aims to stop transmission of infection with mass drug administration (MDA) and to alleviate suffering among people affected by the disease through morbidity management and disability prevention (MMDP).

La filariose lymphatique (FL) est une maladie évitable, incapacitante et défigurante, due à une infestation par des filaires parasites des espèces Wuchereria bancrofti, Brugia malayi et B. timori. On estime que 51,4 millions de personnes sont infectées dans le monde. Le lymphœdème et l’hydr...ocèle sont les conséquences cliniques chroniques visibles de l’altération des vaisseaux lymphatiques causée par la présence de
ces parasites dans l’organisme. Les parasites sont transmis d’une personne à l’autre par l’intermédiaire de moustiques des genres Culex, Anopheles, Mansonia et Aedes. L’année 2020 a marqué la 20e année du Programme mondial pour l’élimination de la filariose lymphatique (GPELF) établi par l’OMS, dont l’objectif est de mettre fin à la transmission de l’infection grâce à l’administration de masse de médicaments
(AMM) et d’alléger les souffrances des malades par la prise en charge de la morbidité et la prévention des incapacités (PMPI).
