HIV testing programmes need to ensure that all clients who test for HIV are provided with correct diagnoses. The accuracy of HIV testing is critical to prevent misdiagnosis, as the consequences of giving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and pu...blic health.
With the evolution of global HIV epidemiology, HIV testing approaches must also evolve to maintain accuracy and efficiency in population-level diagnosis. Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used. As a result of changing epidemiology and declining HIV positivity in testing, WHO recommends all countries use a standard three-test strategy to ensure a PPV of at least 99%, minimizing false-positive misdiagnosis. The WHO-recommended HIV testing strategy, along with quality assurance measures such as retesting to verify a positive diagnosis prior to initiation of HIV treatment, is cost-effective as it prevents misdiagnosis and unnecessary initiation of costly lifelong treatment.
This implementation guide provides practical advice on switching to a three-test strategy and instituting other measures that can help national HIV programmes deliver high-quality, accurate HIV testing services and ensure that misdiagnosis is minimized.

Evidence-based guidelines are one of the most useful tools for improving public health and clinical practice. Their purpose is to formulate interventions based on strong evidence of efficacy, avoid unnecessary risks, use resources efficiently, reduce clinical variability and, in essence, improve hea...lth and ensure quality care, which is the purpose of health systems and services. These guidelines were developed following the GRADE methodology, with the support of a panel of clinical experts from different countries, all convened by the Pan American Health Organization. By responding to twelve key questions about the clinical diagnosis and treatment of dengue, chikungunya, and Zika, evidence-based recommendations were formulated for pediatric, youth, adult, older adult, and pregnant patients who are exposed to these diseases or have a suspected or confirmed diagnosis of infection. The purpose of the guidelines is to prevent progression to severe forms of these diseases and the fatal events they may cause. The recommendations are intended for health professionals, including general, resident, and specialist physicians, nursing professionals, and medical and nursing students, who participate in caring for patients with suspected dengue, chikungunya, or Zika. They are also intended for health unit managers and the executive teams of national arboviral disease prevention and control programs, who are responsible for facilitating the process of implementing these guidelines.

Todos los países de la Región de las Américas en los que la malaria es endémica han asumido el reto de eliminar la enfermedad y de poner en marcha medidas para orientar sus programas y estrategias de salud en esa dirección. En este manual se explica cómo ejecutar las medidas con vistas a logra...r la eliminación de la malaria y prevenir su restablecimiento, mediante el aumento de la intensidad y la calidad de las medidas, la reorientación de las iniciativas, la reducción de los retrasos que favorecen la transmisión y un monitoreo adecuado que permita ajustar las intervenciones. En este sentido, se propone como primer paso estratificar el territorio —de modo que se puedan planificar y priorizar las intervenciones y grupos de población— para, a continuación, aplicar una medida de diagnóstico, tratamiento, investigación y respuesta como estrategia clave dirigida a hacer efectiva la eliminación de la enfermedad y a prevenir su restablecimiento en todos los estratos. Además, el documento trata de hacer operativo el concepto de vigilancia, como intervención promovida por la Organización Mundial de la Salud a través de la Estrategia Técnica Mundial contra la Malaria 2016-2030, y destaca la importancia de que las comunidades tengan acceso al diagnóstico y el tratamiento tempranos. Por último, en el manual también se incluyen aspectos de gestión y monitoreo que deben tenerse en cuenta para la eliminación de los focos de transmisión.

Objetivos: • Fornecer recomendações para as práticas de prevenção e controle de infecções (PCI) a serem usadas durante atendimento em estabelecimentos não tradicionais, no contexto da doença do novo coronavírus (COVID-19). Estas recomendações são provisórias e estão sujeitas à revi...são conforme novas evidências forem disponibilizadas. Principais considerações: • Com uma demanda crescente por leitos hospitalares, existe a necessidade de transformar estabelecimentos não tradicionais em centros de tratamento para pacientes de COVID 19 que não necessitem de hospitalização. • Para os fins deste documento, estabelecimentos não tradicionais são definidos como hotéis, motéis, abrigos, dormitórios e assistência domiciliar. Estas recomendações não se aplicam a centros de quarentena ou instituições de longa permanência para idosos. • É necessário um planejamento abrangente antes do uso de estabelecimentos não tradicionais como locais de assistência à saúde (1). Para garantir os melhores resultados possíveis, medidas de logística, segurança, gerenciamento de resíduos e controle de infecções devem ser implementadas como parte da resposta à pandemia de COVID-19.

Cette ressource a été élaborée pour faciliter le développement de plans d’action nationaux stratégiques et bien coordonnés afin de contrer rapidement la désinformation sur les vaccins et d’encourager la demande de vaccination éclairée par l’écoute sociale.
Introdução: Em março de 2020, a Organização Mundial da Saúde (OMS) declarou que o surto de COVID-19, doença causada por um novo coronavírus, passava a constituir uma pandemia, dada a velocidade e escala de transmissão da doença. A Região das Américas é caracterizada por uma riqueza mult...iétnica e multicultural. No entanto, povos indígenas, afrodescendentes e outros grupos étnicos, muitas vezes, sofrem discriminação e exclusão, e isso leva a desigualdades de saúde. A COVID-19 pode ter um maior impacto em certos grupos da população, como povos indígenas e afrodescendentes. Em 2017, os Estados Membros da Organização Pan-Americana da Saúde (OPAS) aprovaram a primeira Política de Etnia e Saúde (documento CSP29/7, Rev.1), baseada no reconhecimento de diferenças entre grupos étnicos, bem como em seus respectivos desafios, necessidades e contextos históricos. A política também reforça a necessidade de uma abordagem intercultural, fundamentada na igualdade e no respeito mútuo, para melhorar os desfechos de saúde e avançar em direção à saúde universal. A OPAS prioriza a etnia como uma questão de caráter transversal no gerenciamento de emergências e desastres. Isso está refletido em uma série de regulamentos, como o Plano de Ação 2016-2021 para a Redução do Risco de Desastres e outros manuais, diretrizes e iniciativas.

During fresh fruit and vegetables (FFV) production, water is used for a variety of purposes. Even the water was conventionally treated and disinfected, it may still potentially contain human pathogens, albeit at low concentrations. A risk assessment, appropriate to the national or local production c...ontext, should be conducted to assess the potential risks associated with a specific water source or supply in order to devise the appropriate risk mitigation strategies.
Since the 48th session of Codex Committee on Food Hygiene (CCFH) noted the importance of water safety and quality in food production and processing, FAO and WHO has undertaken the work on this subject. This report describes the output of the third in a series of meetings, which examined appropriate and fit-for-purpose microbiological criteria for water used with fresh fruit and vegetables. The advice herein will support decision making when applying the concept of fit-for-purpose water for use in the pre- and post-harvest production of fresh fruit and vegetables.

La résistance aux antimicrobiens (ou RAM, cette abréviation étant est ici également employée en mode adjectif pour désigner les organismes « résistants aux antimicrobiens ») est une préoccupation majeure pour la santé publique mondiale et une question de sécurité san...itaire des aliments. Lorsque des pathogènes deviennent résistants aux agents antimicrobiens, ils peuvent présenter un risque plus important pour la santé découlant d’un éventuel échec thérapeutique, de la diminution de choix thérapeutiques et de la probabilité accrue d’apparition et de gravité de la maladie. Les problèmes en rapport avec la RAM sont liés de façon inhérente à l’usage des antimicrobiens dans tous les types d’environnements, y compris les utilisations humaines et non humaines. L'utilisation d’agents antimicrobiens dans la production alimentaire animale et végétale représente un facteur de risque important pour la sélection et la transmission de micro-organismes résistants aux antimicrobiens (micro-organismes RAM) et de déterminants de la résistance aux antimicrobiens (déterminants de la RAM) des animaux et des plantes alimentaires à l’humain par sa consommation d’aliments.
