The report demonstrates that the current system—at both national and international levels— was not adequate to protect people from COVID-19. The time it t...ook from the reporting of a cluster of cases of pneumonia of unknown origin in mid-late December 2019 to a Public Health Emergency of International Concern being declared was too long. February 2020 was also a lost month when many more countries could have taken steps to contain the spread of SARS-CoV-2 and forestall the global health, social, and economic catastrophe that continues its grip. The Panel finds that the system as it stands now is clearly unfit to prevent another novel and highly infectious pathogen, which could emerge at any time, from developing into a pandemic.

The primary audience for this guidance is persons
working directly in vector-borne disease prevention
and control, including programme managers,
researchers and field workers. A brief technical
background is provided for the benefit of persons
without expertise in vector-borne diseases; readers...
working in the field may wish to skip the background
section and begin with the discussion of ethical
issues and values in Chapter 3. The guidance cannot
offer universally applicable answers to the complex
ethical issues raised, nor can it provide a checklist of
issues that are necessarily relevant in all situations.
Rather, its goal is to help readers recognize aspects
of their work that raise significant ethical challenges
and to respond to these challenges in accordance
with internationally accepted values and norms.

Cet article fait partie d’une série d’explications à propos de la mise au point et de la distribution des vaccins.
Infectious diseases cause over one billion human infections per year, with millions of deaths each year globally. Extensive health and financial burden is seen from both established and emerging infectious diseases. Infectious diseases also affect plants and animals, which may pose threats to agricu...lture and water supplies with additional impacts on human health. This Question and Answers, prepared by the World Health Organization (WHO) and Convention on Biological Diversity (CBD) Secretariat under their joint work programme on biodiversity and health, and launched of the occasion of the International Day for Biodiversity 2020, summarizes some of the interlinkages between biodiversity and infectious diseases.
WHO is continuously monitoring and responding to the COVID 19 outbreak. This Q&A will be updated as more is known about COVID-19, how it is affecting people worldwide, and the effectiveness of interventions against the disease.

The emergence and transmission of zoonotic diseases are driven by complex interactions
between health, environmental, and socio-political systems. Human movement is considered
a significant and increasing factor in these processes, yet forced migration remains an
understudied area of zoonotic res...earch–due in part to the complexity of conducting interdisciplinary
research in these settings.

The 20th century was a period of unprecedented ecological change, with dramatic reductions in natural ecosystems and biodiversity and equally dramatic increases in people and domestic animals. Never before have so many animals been kept by so many people—and never before have so many opportunities... existed for pathogens to pass from wild and domestic animals through the biophysical environment to affect people causing zoonotic diseases or zoonoses. The result has been a worldwide increase in emerging zoonotic
diseases, outbreaks of epidemic zoonoses as well as a rise in foodborne zoonoses globally, and a troubling persistence of neglected zoonotic diseases in poor countries.

Climate change is expected to have complex effects on infectious diseases, causing some to increase, others to decrease, and many to shift their distributions. There have been several important advances in understanding the ...role of climate and climate change on wildlife and human infectious disease dynamics over the past several years. This essay examines 3 major areas of advancement, which include improvements to mechanistic disease models, investigations into the importance of climate variability to disease dynamics, and understanding the consequences of thermal mismatches between host and parasites. Applying the new information derived from these advances to climate–disease models and addressing the pressing knowledge gaps that we identify should improve the capacity to predict how climate change will affect disease risk for both wildlife and humans.

The social impacts of Covid-19 in Brazil: vulnerable populations and responses to the pandemic
Passados os primeiros meses da pandemia do novo coronavírus no Brasil, o Observatório Covid-19 Fiocruz, em parceria com a Editora Fiocruz e com o apoio da Rede SciELO Livros, traz para o público leitor... um conjunto de livros instantâneos sobre as análises nele realizadas desde que foi criado para subsidiar o seu combate. Nesta série Informação para Ação na Covid-19 será apresentado um balanço do conjunto de documentos (notas e relatórios técnicos, boletins, ensaios, informes, recomendações, ensaios, artigos, entre outros) produzidos em resposta à pandemia. Cada volume da série se estrutura em torno de um tema: aspectos globais da pandemia e da diplomacia em saúde; cenários epidemiológicos e vigilância em saúde; as políticas e a gestão dos serviços e sistemas de saúde; orientações para os cuidados e a saúde dos trabalhadores da saúde; impactos sociais e desigualdades sociais na pandemia. Com a publicação destes estudos em livros instantâneos e de acesso aberto colocamos à disposição do público o conjunto de informações e conhecimentos gerados no âmbito do Observatório Covid-19 Fiocruz, realizamos um balanço e uma reflexão sobre como chegamos ao cenário atual e apontamos caminhos para um futuro próximo.

Parasites & Vectors volume 11, Article number: 264 (2018)
Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

This study shows the importance of an integrated entomological and medical surveillance for the evaluation of arboviral disease risk, which is a precondition for designing cost-effective vector control programs.
The purpose of this guide is to provide practical advice for health staff undertaking infectious disease preparedness and response activities to ensure that access to safe abortion care (SAC) is maintained when an infectious disease outbreak occurs. It is an operational guide which can serve to supp...ort health actors to maintain SAC services during outbreaks and ensure that necessary SAC considerations are integrated within outbreak responses; it is not a clinical guide. The locational focus of this document is humanitarian and fragile settings; however, recommendations may apply to infectious disease outbreaks in all low-resource populations. This guide is intended to complement Sexual and Reproductive Health and Rights During Infectious Disease Outbreaks: Operational Guidance for Humanitarian and Fragile Settings.
