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.

Chagas disease, also known as American trypanosomiasis, is a neglected tropical disease transmitted by triatomine insects, first identified in 1909. Chagas disease affects approximately 6–7 million peop...le globally and is highly prevalent in Latin America where most cases are reported. However, there is increasing evidence that Chagas disease is now an important public health issue outside the “classical” endemic countries due to population migration. Our understanding of Chagas disease, including its pathologies and factors relating to progression, remains to date limited, and is also challenged by lack of diagnosis and highly effective treatment. This systematic review aims to describe studies with Chagas patients receiving antiparasitic treatment. Databases were searched for relevant studies published after 1997, and the results of these searches were screened.

Under-diagnosis of asthma in ‘under-fives’ may be alleviated by improved inquiry into disease history. We assessed a questionnaire-based screening tool for asthma among 614 ‘under-fives’ with severe respiratory illness in Uganda. The questionnaire responses were compared to post hoc consensu...s diagnoses by three pediatricians who were guided by study definitions that were based on medical history, physical examination findings, laboratory and radiological tests, and response to bronchodilators. Children with asthma or bronchiolitis were categorized as “asthma syndrome”. Using this approach, 253 (41.2%) had asthma syndrome. History of and present breathing difficulties and present cough and wheezing was the best performing combination of four questionnaire items [sensitivity 80.8% (95% CI 77.6–84.0); specificity 84.7% (95% CI 81.8–87.6)]. The screening tool for asthma syndrome in ‘under-fives’ may provide a simple, cheap and quick method of identifying children with possible asthma. The validity and reliability of this tool in primary care settings should be tested.

T The Compendium has been developed as a clear and concise instrument to facilitate the understanding and planning of delivery of high-quality care for everybody affected by TB. It incorporates all recent policy guidance from WHO; follows the care pathway of persons with signs or sympt...oms of TB in seeking diagnosis, treatment and care; and includes key algorithms and cross-cutting elements that are essential to a patient-centered approach in the cascade of TB care.
The Compendium is structured into 33 WHO standards and consolidates all current WHO TB policy recommendations into a single resource, with electronic links to the individual, comprehensive WHO policy guidelines

Orientations provisoires
20 mars 2020
Ce document résume les orientations actuelles de l'OMS pour la surveillance mondiale de la COVID-19 chez l'homme, due à une infection par le nouveau coronavirus 2019. Ces orientations sont à lire en se référant aux orientations de l'OMS sur les activit...és de préparation opérationnelle et de riposte, dans lesquelles l'identification et le dépistage actifs des cas, ainsi que la recherche des contacts sont fortement recommandés dans tous les scénarios de transmission. La notification globale des cas doit être considérée comme une mesure provisoire uniquement lorsque la notification des cas individuels n'est pas possible. L’OMS continuera de mettre à jour ces orientations au fur et à mesure que de nouvelles informations sur la COVID-19 seront disponibles.

Malaria is a prevalent cause of febrile illnesses in areas with high transmission, and its clinical presentation overlaps with initial signs of Ebola disease. For this reason, the effectiveness of the Ebola response in Guinea, Liberia and Sierra Leone can be optimized through the deployment of targe...ted measures to reduce the number of fever cases due to malaria
WHO recommends specific adaptations in the diagnosis of malaria and in LLIN distribution in countries heavily affected by the Ebola outbreak and mass drug administration using artemisinin-based combination therapies (ACTs) in areas where transmission of both Ebola and malaria is high and access to malaria treatment is very low.
