Hepatitis B (HBV) infection is a major public health problem and cause of chronic liver disease.
The 2024 HBV guidelines provide updated evidence-informed recommendations on key priority topics. These include expanded and simplified treatment criteria for adults but now also for adolescents; expa...nded eligibility for antiviral prophylaxis for pregnant women to prevent mother-to-child transmission of HBV; improving HBV diagnostics through use of point-of-care HBV DNA viral load and reflex approaches to HBV DNA testing; who to test and how to test for HDV infection; and approaches to promote delivery of high-quality HBV services, including strategies to promote adherence to long-term antiviral therapy and retention in care.
The 2024 guidelines include 11 updated chapters with new recommendations and also update existing chapters without new recommendations, such as those on treatment monitoring and surveillance for liver cancer.

L’objectif des lignes directrices 2024 est de fournir des recommandations actualisées et fondées sur
des données probantes sur les principaux sujets prioritaires. Ceux-ci concernent notamment les critères élargis et simplifiés de mise sous traitement pour les adultes, mais aussi désormais ...pour les adolescents, l’élargissement des critères d’éligibilité au traitement
antiviral prophylactique pour les femmes enceintes
afin de prévenir la transmission mère-enfant du VHB,
l’amélioration des tests de diagnostic de l’infection par le
VHB grâce à l’utilisation de tests de mesure de la charge
virale du VHB (ADN) sur le lieu de soins (“point-of-care
tests”) et d’approches réflexes pour la recherche de
l’ADN du VHB, et les critères pour déterminer à qui et
comment faire le test pour rechercher une infection par
le VHD.

On August 13, 2024, the Africa CDC declared the mpox outbreak a Public Health Emergency of Continental Security (PHECS). The following day, the WHO declared it a Public Health Emergency of International Concern (PHEIC). A coordinated, continent-wide response is essential, co-led by the African Union... (AU) through the Africa CDC and the World Health Organization (WHO), in close collaboration with global partners working under a unified plan, budget, and monitoring framework.

Smallpox eradication was certified in 1980. Mpox has been endemic in Central and West African countries since it was first detected in 1958 . It is a zoonosis; cases are often found close to tropical rainforests where various animals carry the orthopoxvirus that causes the disease. In endemic countr...ies, most mpox infections in humans result from a primary animal-to-human transmission. Human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person, or recently contaminated objects. Transmission can also occur via the placenta from mother to fetus or through close contact during and after birth.

Pneumonia and diarrhoea account for 23% of under-five mortality and were responsible for an estimated 1.17 million deaths in children under five globally. Furthermore, pneumonia and diarrhoea were responsible for 18% of mortality in children 5–9 years of age, resulting in an estimated 86 000 preve...ntable deaths globally in 2021. Existing World Health Organization (WHO) guidance on the clinical management of pneumonia and diarrhoea has mainly focused on children less than 5 years of age.

Mpox can spread in humans through close contact, usually skin-to-skin contact, including sexual contact, with an infected person or animal, as well as with materials contaminated with the virus such as clothing, beddings and towels, and respiratory droplets in prolonged face to face contact. People ...remain infectious from the onset of symptoms until all the lesions have scabbed and healed. The virus may spread from infected animals through handling infected meat or through bites or scratches. Diagnosis is confirmed by polymerase chain reaction (PCR) testing of material from a lesion for the virus’s DNA.

Effective malaria case management requires quick access to diagnostics and antimalarial treatments to reduce illness and death. Artemisinin-based combination therapy (ACT) has been essential to malaria treatment since 2001, as it combines artemisinin for rapid parasite reduction with a partner drug ...to ensure complete cure. However, resistance to antimalarial drugs, where parasites survive standard doses, threatens malaria control.

mise à jour de la situation
This document serves to provide interim guidance/ recommendations to carry out mpox surveillance activities mainly case investigation, contact tracing and isolation. For the development of this document WHO, UKHSA and CDC guidelines were referred to and adopted within the country context.
The conditionality of this recommendation is largely driven by the current higher unit cost of pyrethroid-PBO ITNs compared
to pyrethroid-only LLINs and therefore the uncertainty of their cost-effectiveness. Furthermore, as PBO is less wash-resistant
than pyrethroids, its bioavailability declines ...faster over the three-year estimated life of an ITN; therefore, the added impact of
pyrethroid-PBO ITNs over that of pyrethroid-only LLINs may decline over time. The evidence comes from two sites in
eastern Africa with pyrethroid resistance and not from other geographies where transmission levels and vector characteristics
may vary. PBO acts by inhibiting certain metabolic enzymes, primarily oxidases, and so are likely to provide greater protection
than pyrethroid-only LLINs where mosquitoes display mono-oxygenase-based insecticide resistance mechanisms.

The MSF malaria guidelines provide practical, evidence-based recommendations for diagnosing, treating, and preventing malaria, especially in low-resource settings. They cover uncomplicated and severe cases, recommend rapid tests and artemisinin-based therapies, and include special guidance for vulne...rable groups like children and pregnant women.

Malaria in pregnancy is a significant health problem in malaria-endemic areas. It not only causes substantial childhood morbidity and mortality but also increases the risks of adverse events for pregnant women and their developing fetuses. Most of the burden in these areas is due to infection with P...lasmodium falciparum. Artemisinin-based combination therapy (ACT) has been recommended as first-line treatment for uncomplicated P. falciparum malaria in all populations, including pregnant women in their second and third trimesters, since 2006. However, for women in their first trimester of pregnancy, WHO recommended as first-line treatment a combination of quinine and clindamycin.
Based on a review of the evidence conducted in 2022, WHO now recommends artemether–lumefantrine, the ACT with the most human safety data available, as the preferred treatment for uncomplicated P. falciparum malaria in the first trimester of pregnancy. This document presents all relevant evidence on the effects and safety in early pregnancy of artemisinins and partner medicines used in ACTs from both studies in experimental animals and observational studies in humans.

This toolkit is a comprehensive set of practical tools and resources designed to support country-level risk communication and community engagement (RCCE) practitioners, decision-makers, and partners to plan and implement readiness and response activities for yellow fever outbreaks. The toolkit conta...ins: information about yellow fever; RCCE considerations for how to approach key issues during yellow fever outbreaks; tools for understanding the context in which yellow fever outbreaks occur; methods for collecting data to inform strategy development and bring evidence into planning and implementation of activities; guidance to support vector control and immunization campaigns; and links to existing RCCE tools and training. It is one of a suite of toolkits on RCCE readiness and response to a range of disease and response areas.
