The larval stage of the parasite Taenia solium can encyst in the central nervous system causing neurocysticercosis, which is the main cause of acquired epilepsy in the countries in which the parasite is endemic. Endemic areas are those with the presence (or likely presence) of the full life cycle of... Taenia solium. The parasite is most prevalent in poor and vulnerable communities in which pigs roam free, open defecation is practiced, basic sanitation is deficient, and health education is absent or limited. Several tools are available for the control of Taenia solium. Preventive chemotherapy for Taenia solium taeniasis, which is directed at the adult tapeworm, is one of them. Other tools focus on pig management, pig vaccination and treatment, sanitation and hygiene, and community education. Three potential drugs—niclosamide, praziquantel, and albendazole—have been considered for use for preventive chemotherapy in Taenia solium taeniasis control programs through mass drug administration or targeted chemotherapy. In this Guideline, we provide recommendations for preventive chemotherapy in Taenia solium-endemic areas using niclosamide, praziquantel, or albendazole, including at which dose and in which population groups.

Le cycle de transmission
Téniase. Les ténias vivent dans l’intestin des êtres humains. Les œufs du ténia sont libérés avec les matières fécales. En cas de défécation à l’air libre, l'environnement (en particulier les légumes et l'eau) peut être contaminé. Cysti...cercose humaine. L'ingestion d'œufs de ténia (due à une mauvaise hygiène après l'utilisation des toilettes ou à la consommation d'eau ou d'aliments contaminés), entraîne le développement de kystes parasitaires principalement dans le cerveau (provoquant notamment des crises d’épilepsie). Cysticercose porcine. Les porcs mangeant des œufs de ténia (présents dans les matières fécales ou l'environnement) développent des kystes parasitaires principalement dans les muscles (viande). La viande infectée contient des kystes parasitaires qui ne sont pas toujours faciles à voir. La consommation de viande de porc infectée, crue ou mal cuite, entraîne le développement du ténia.
Les mesures de prévention et de contrôle
Les médicaments prescrits dans les centres de santé peuvent traiter l'infection par le ténia. Lavez vos mains avec de l'eau et du savon après avoir utilisé les toilettes. Rincez soigneusement les légumes ou faites-les cuire avant de les manger. Utilisez les toilettes ou les latrines pour éviter la contamination de l'environnement, des porcs et des autres personnes. Garder les porcs dans des enclos pour les empêcher d’être infectés. Vaccinez et traitez les porcs pour prévenir l'infection. L'inspection des viandes permet d'identifier les porcs fortement infectés. Faites bien cuire la viande de porc (elle ne doit plus être rose) pour tuer le parasite.

Mycetoma is a chronic, progressively destructive infectious disease of the subcutaneous tissues, affecting skin, muscle and bone. Mycetoma occurs in tropical and subtropical environments characterized by short rainy seasons and prolonged dry seasons that favour the growth of thorny bushes. Global bu...rden is not known, but the disease is endemic; it has been reported from countries in Africa, Asia, Europe and Latin America. This course addresses the epidemiology of mycetoma, clinical features, diagnosis, treatment, and public health interventions.

Leishmaniasis is a parasitic disease that is found in parts of the tropics, subtropics, and southern Europe. Leishmaniasis is caused by infection with Leishmania parasites, which are spread by the bite of infected sand flies. There are several different forms of leishmaniasis in people. The most com...mon forms are cutaneous leishmaniasis, which causes skin sores, and visceral leishmaniasis, which affects several internal organs (usually spleen, liver, and bone marrow).

This update of the Guidelines for poison control, entitled Guidelines for establishing a poison centre, reflects the development of the role of poison centres in public health and the sound management of chemicals, described in section 1, and the opportunities provided by new technology. Assessments... carried out under the IHR show
continuing gaps in capacity for managing chemicals (2). In particular, many countries still lack access to poison
centre services (3). There is therefore demand for updated guidance.

Areas of Africa endemic for Buruli ulcer (BU), caused by Mycobacterium ulcerans, also have a high prevalence of human immunodeficiency virus (HIV), with adult prevalence rates between 1% and 5% (Maps). However, there is limited information on the prevalence of BU–HIV coinfection.... Preliminary
evidence suggests that HIV infection may increase the risk of BU disease (1–3). In the Médecins Sans Frontières project in Akonolinga, Cameroon, HIV prevalence was approximately 3–6 times higher among BU patients than the regional estimated HIV prevalence (2). Similarly in Benin and Ghana, BU
patients were 8 times and 3 times respectively more likely to have HIV infection than those without BU (1, 3). Further study is needed to clarify this association and enhance knowledge about the prevalence ofBU–HIV coinfection in endemic areas.

In areas of Mexico, Central America, and South America, where the Trypanosoma cruzi parasite is present in triatomine bugs, improved housing and spraying insecticide inside housing to eliminate the bugs has significantly decreased the spread of Chagas disease. Screening of blood donations for Chagas... is another important public health tool to help prevent spreading the disease through blood transfusions. Early detection and treatment of new cases, including mother-to-baby (congenital) cases, will also help reduce the burden of disease.

This document focuses on making recommendations for the diagnosis and treatment of Chagas disease, an infection caused by Trypanosoma cruzi, the protozoan agent of a systemic parasitic disease. Methodology: These clinical practice guidelines were prepared following the WHO handbook for guideline dev...elopment (5). A multidisciplinary development group was formed, comprised of thematic experts, epidemiologists, methodologists, and users. Since there were no existing guidelines that could be adapted, the guidelines were developed from scratch.

Dengue is the fastest spreading, mosquito-borne viral infectious disease worldwide, with remarkable morbidity and mortality. In the past decades, profound contributions have been made towards understanding its epidemiology, including disease burden and distributions, risk factors, and control and pr...evention practices. Dengue continues to disseminate to new areas, including high latitude regions, and a new serotype (dengue virus serotype 5) has been identified. Vaccine research has made new progress, in which the licensed yellow fever and dengue virus quadrivalent chimeric vaccine is now under further safety assessment. In disease surveillance, because of its operational simplicity, rapidity, capability, and utility as an indicator of disease severity, dengue virus NS1 antigen detection has great promotion and application value among primary health care institutions. Vector control progress has driven new breakthroughs in biotechnology, including Wolbachia-infected Aedes and genetically modified Aedes. Both Aedes variants have been used to block transmission of the dengue virus through population replacement and suppression. In the future, vector control should still be pursued as a key measure to prevent transmission, along with anti-viral drug and vaccine research.
