Les maladies infectieuses sont en constante mutation. De nouvelles maladies apparaissent, d’autres qui sont bien connues se propagent ou refont surface, et quelques rares fois, une maladie est éradiquée. Les maladies infectieuses telles que le VIH, la tuberculose et le choléra sont des causes c...onsidérables de morbidité et de mortalité dans plusieurs régions du monde. Le personnel de la santé joue un rôle primordial, en ce qui concerne la protection de leurs clients contre les maladies infectieuses et leurs traitements en cas d’infection. Dans le cadre de leur travail, le personnel de santé accomplisse des tâches cliniques ou autres activités susceptibles de les exposer ainsi que leurs clients aux microorganismes – orga- nismes potentiellement infectieux. Bon nombre de ces clients sont malades et, par conséquent, sont plus vulnérables aux infections ou peuvent avoir des infec-tions susceptibles d’être transmises à d’autres personnes. Par chance, l’ensemble du personnel travaillant dans les services de santé est en mesure d’exécuter des procédés simples visant à minimiser le risque – vis-à-vis d’eux-mêmes et de leurs clients – et réduire la propagation des infections. Ces pratiques peuvent être intégrées à moindre frais dans les habitudes quotidiennes au sein des établissements de santé du monde entier. Ce guide de référence est spécialement conçu pour l’emploi à tous les niveaux du système sanitaire, depuis les plus grands hôpitaux jusqu’aux plus petits dispensaires ou centres de santé, dans des établissements où les ressources sont rares.Ce guide, publié pour la première fois en 1999, a été mis à jour. Bien que la plu-part des pratiques restent inchangées, il a fait l’objet de quelques modifications significatives – par exemple, concernant les recommandations liées au lavage des mains et aux précautions standard. Toutefois, ce guide continue de présenter des recommandations pratiques en matière de procédés simples et relativement peu coûteux pouvant être exécutés partout, à l’aide des matériels de base et des équi-pements de niveau technologique moyen.

La deuxième Enquête sur la prestation des services de soins de santé du Rwanda (EPSR-II), réalisée en 2007, est une enquête représentative au niveau national au cours de laquelle un échantillon de 538 établissements de santé ont été enquêtés. L’enquête a couvert les ôpitaux, les ce...ntres de santé, les dispensaires et les postes de santé et a inclus tous les établissements publics, qu’ils appartiennent au secteur gouvernemental ou Agréé, et la plupart des établissements privées. L’EPSR-II a collecté des informations sur les capacités des
établissements à fournir des services de qualité ainsi que sur l’existence de systèmes effectifs garantissant des services de qualité, par le biais d’interviews effectuées auprès des prestataires de santé et des patients ainsi que par le biais d’observations de consultations de patients ; ces informations concernent essentiellement l’infrastructure d’ensemble de l’établissement ainsi que les services de santé maternelle, infantile, de santé de la reproduction, de tuberculose, du paludisme, des infections sexuellement transmissibles (IST) et du VIH/sida. L’objectif de cette étude est, d’une part, d’évaluer les forces et faiblesses de l’infrastructure et des systèmes de support de ces services et, d’autre part, d’évaluer le niveau d’adhésion des prestataires aux standards de prestation des services.

The meeting was held from 26 to 27 March 2018 to review and discuss the following topics:
Advances and challenges in the use of fTLC, and new approaches to detecting mycolactone using monoclonal antibodies (mAbs).
The status of development of rapid diagnostic tests (RDTs) targeting the MUL..._3720 protein.
The role of PCR as a reference test, and hurdles in providing a confirmatory diagnosis and in establishing a quality assurance programme.
New molecular tools with potential for implementation at a level lower than in the national or regional reference laboratory, such as loop-mediated isothermal amplification (LAMP) and recombinase polymerase amplification (RPA).
The need to harmonize and standardize methods for collection and preparation of specimens, so samples can be referred for diagnosis and stored for evaluation of new diagnostic tests in optimal conditions.
Barriers to accessing early diagnosis and treatment, including coordination at the programme level, and lack of adequate diagnostic tools.
Defining target product profiles (TPPs) to guide the development of new diagnostic tools that can be applied at different levels of the health system. Participants agreed that two TPPs would be developed to address the current gaps: (i) a rapid test for BU diagnosis at the primary health-care level; and (ii) a test for diagnosis of BU that can also assist in treatment monitoring and differential diagnosis at the district hospital or reference centre.

Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is lim...ited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

Vector-borne diseases are responsible for 17% of the global burden of communicable diseases and more than 500 000 deaths annually. The ambitious global targets for the control of vector-borne diseases come in the context of the (re-)emergence of diseases, increasing resistances to insecticides and u...ncertainty related to the financing of global vector control efforts. The United Nations 2030 Agenda with its related Sustainable Development Goals (SDGs), the New Urban Agenda adopted at the United Nations Conference on Housing and Sustainable Urban Development (Habitat III)
in Quito in 2016 and WHO’s Global vector control response 2017–2030 (WHO, 2017a) emphasize the value of elevating multisectoral actions and strategies that extend beyond the health sector to the core of integrated vector control.
This policy brief underlines the important role housing conditions have in the transmission of vector-borne diseases and showcases interventions and policies the housing sector can contribute to effective, integrated and intersectoral vector-borne diseases management.

This document outlines the evaluation process that WHO undertakes to assess novel tools and strategies targeted at VBDs. Its aim is to articulate the linkage between the generation of evidence that demonstrates public health impact of novel interventions, and the development of policy recommendation...s based on the generated data. The document defines standards for the evaluation process, as well as the steps that an applicant needs to undertake, along with some guiding principles that aim to support applicants in the development of submissions with WHO.

The main purpose of the meeting was to review tsetse control tools, activities and their contribution to the elimination of gHAT and the monitoring thereof. Seven endemic countries provided reports on recent and ongoing vector control interventions at the national level (Angola, Cameroon, Côte d’...Ivoire, Chad, Democratic Republic of the Congo, Guinea and Uganda). Country reports focused on the in situations implementing and supporting vector control activities, the tools and the approaches in use, the coverage of the activities in space and time and their impacts on tsetse populations. Future perspectives for vector control in the respective countries were also discussed, including opportunities and challenges to sustainability.
