It is impossible to address the many complex needs of respiratory virus surveillance with a single surveillance system. Multiple systems, investigations and studies must each be fit-for-purpose to specific priority surveillance objectives, and only together can they provide essential information to ...policy-makers. In essence, each surveillance approach fit together as “tiles in a mosaic” that provides a complete picture of respiratory viruses and the impact of associated illnesses and interventions at the country level. This mosaic framework demonstrates how surveillance approaches may be implemented as coordinated and collaborative systems, well-matched to specific priority objectives.

Reports of antimicrobial-resistant (AMR) microorganisms are increasing globally, threatening to render existing treatments ineffective against many infectious diseases. In Africa, AMR has already been documented to be a problem for human immunodeficiency virus (HIV) and the pathogens that cause mala...ria, tuberculosis (TB), typhoid, cholera, meningitis, gonorrhoea and dysentery. Recognizing the urgent need for action, the 2016 United Nations (UN) General Assembly approved a resolution to ensure sustained and effective global action to address AMR.

This document focus on the direct consequences of the virus (morbidity and mortality) in specific populations and on the results of measures aimed at mitigating the spread of the virus, with indirect impacts on socio-economic conditions. In this complex scenario, the gender approach has not received... due attention during the pandemic. Gender is one of the structural determinants of health, but it does not appear in analyses of the direct and indirect effects of the pandemic, despite being essential in the recognition and analysis of the differential impacts on men and women and their interaction with the different determinants of health.

The emergence of COVID-19 has drawn the attention of health researchers sharply back to the role that food systems can play in generating human disease burden. But emerging pandemic threats are just one dimension of the complex relationship between agriculture... and infectious disease, which is evolving rapidly, particularly in low-income and middle-income countries (LMICs) that are undergoing rapid food system transformation. This changing relationship is examined through four current disease issues.

Previous crises, such as the Ebola virus disease (EVD) in West Africa in 2014, indicate the direct impact movement restrictions and disease containment efforts have on food availability, access, utilization and violence – particularly gender-based violence (GBV). The importance of maintaining and ...upscaling food security interventions for the most vulnerable populations, alongside the health sector’s efforts to avert disease spread, is therefore undeniable. The COVID-19 outbreak in South Sudan threatens to paralyze an already fragile food system and negatively impact more than 6.5 million people in South Sudan who remain vulnerable. At the same time, the core national capacities for prevention, preparedness and response for public health events is limited, and the healthcare system has been weakened by years of conflict, poor governance and low investments.

To guide One Health capacity building efforts in the Republic of Guinea in the wake of the 2014–2016 Ebola virus disease (EVD) outbreak, we sought to identify and assess the existing systems and structures for zoonotic disease detection and control. We partnered with the government ministries resp...onsible for human, animal, and environmental health to identify a list of zoonotic diseases – rabies, anthrax, brucellosis, viral hemorrhagic fevers, trypanosomiasis and highly pathogenic avian influenza – as the country's top priorities. We used each priority disease as a case study to identify existing processes for prevention, surveillance, diagnosis, laboratory confirmation, reporting and response across the three ministries. Results were used to produce disease-specific systems “maps” emphasizing linkages across the systems, as well as opportunities for improvement. We identified brucellosis as a particularly neglected condition. Past efforts to build avian influenza capabilities, which had degraded substantially in less than a decade, highlighted the challenge of sustainability. We observed a keen interest across sectors to reinvigorate national rabies control, and given the regional and global support for One Health approaches to rabies elimination, rabies could serve as an ideal disease to test incipient One Health coordination mechanisms and procedures. Overall, we identified five major categories of gaps and challenges: (1) Coordination; (2) Training; (3) Infrastructure; (4) Public Awareness; and (5) Research. We developed and prioritized recommendations to address the gaps, estimated the level of resource investment needed, and estimated a timeline for implementation. These prioritized recommendations can be used by the Government of Guinea to plan strategically for future One Health efforts, ideally under the auspices of the national One Health Platform. This work demonstrates an effective methodology for mapping systems and structures for zoonotic diseases, and the benefit of conducting a baseline review of systemic capabilities prior to embarking on capacity building efforts.

Esta primeira versão de Medicamentos para prevenção da COVID-19: Orientação dinâmica da OMS aborda o uso de hidroxicloroquina para prevenção da COVID-19. Segue-se a publicação de uma análise sistemática e NMA que reuniu dados de seis estudos com 6.059 participantes que não tinham COVID-...19 e receberam hidroxicloroquina. Três estudos envolveram participantes que tiveram uma exposição conhecida a uma pessoa com infecção por SARS-CoV-2. Em resposta à divulgação dos dados de estudos, o GDG da OMS desenvolveu recomendações sobre a hidroxicloroquina, um agente anti-inflamatório que atua por meio do bloqueio dos receptores Toll-like, reduzindo a ativação das células dendríticas. É usada para tratar a artrite reumatoide e o lúpus eritematoso sistêmico. Tem um efeito antiviral contra muitos vírus in vitro, inclusive o SARS-CoV-2, mas não foi demonstrado um efeito antiviral clinicamente útil para nenhuma infecção viral.

This country profile presents a summary and analysis of Argentina's status with yellow fever. It is part of a series of profiles on this topic, each focusing on a different country in the Region of the Americas. Argentina's geographical location presents a wide territorial extension throughout diffe...rent latitudes, which determines a wide climatic variety, maintaining the conditions for the enzootic transmission of the yellow fever virus in jungle areas of the northeast of the country bordering Brazil and Paraguay. After controlling the major urban epidemics that hit the port city of Buenos Aires in the 20th century, Argentina maintains foci of enzootic activity in the northeast and isolated human cases for jungle acquisition. The increases in viral activity usually occur in a regional context of epizootics that affect southern Brazil and eastern Paraguay. Argentina has not presented autochthonous cases since 2008. Outbreaks have been sporadic with long intervals without evidence of viral activity.

O Plano Nacional de Preparação e Resposta para a doença por novo coronavírus (COVID-19) é uma ferramenta estratégica de preparação e resposta a uma potencial epidemia pelo vírus SARS-CoV-2. Este Plano tem como referencial as orientações da Organização Mundial da Saúde e do Centro Europ...eu de Prevenção e Controlo de Doenças, sendo o documento de referência nacional no que respeita ao planeamento da resposta a COVID-19. Apesar do conhecimento atualmente disponível em relação a características do SARSCoV-2 nomeadamente o seu comportamento patogénico, potencial de transmissibilidade e outros fatores determinantes não estar completo, é útil considerar, para efeitos de implementação de medidas, uma analogia entre a atual epidemia por SARS-CoV-2 e a gripe pandémica. Apesar de desafiantes, estas características tornam ainda mais premente o planeamento estruturado para diferentes cenários nesta emergência de saúde pública.

Background: Atherosclerotic cardiovascular diseases (ASCVD) including myocardial infarction, stroke and peripheral arterial disease continue to be major causes of premature death, disability and healthcare expenditure globally. Preventing the accumulation of cholesterol-containing atherogenic lipopr...oteins in the vessel wall is central to any healthcare strategy to prevent ASCVD. Advances in current concepts about reducing cumulative exposure to apolipoprotein B (apo B) cholesterol-containing lipoproteins and the emergence of novel therapies provide new opportunities to better prevent ASCVD. The present update of the World Heart Federation Cholesterol Roadmap provides a conceptual framework for the development of national policies and health systems approaches, so that potential roadblocks to cholesterol management and thus ASCVD prevention can be overcome.
