Every country has been affected by COVID-19, with nearly a quarter
of a billion cases and almost 5 million deaths reported globally as of
end of September 2021. Despite the stunning speed with which highly
effective and safe vaccines have been developed, new waves of disease
are still pushin...g health systems to the breaking point, increasingly
transmissible variants are emerging, some survivors are suffering
serious long-term sequelae, and the International Monetary Fund
estimates that global economic losses could exceed US$5.3 trillion
by 2026, if COVID-19 becomes endemic.
Although over 6 billion doses of COVID-19 vaccine have already been
administered, and global production is now reaching 1.5 billion doses
per month, the world is not positioned to end the pandemic. In areas of
high vaccine coverage, there have been massive reductions in serious
disease, hospitalization and death but, globally, vaccine access is highly
inequitable with coverage ranging from 1% to over 70%, depending
largely on a country’s wealth. Consequently, SARS CoV-2 variants
continue to emerge, causing surges of disease and slowing or even
reversing the reopening of societies and economies.

La détection directe des protéines virales du SRAS-CoV-2 (antigènes) dans les écouvillons nasaux et autres sécrétions respiratoires à l'aide de tests immunologiques à flux latéral (également appelés tests de diagnostic rapide, TDR) offre une méthode plus rapide et moins coûteuse pour te...ster le SRAS-CoV-2 que la méthode de référence, les tests d'amplification des acides nucléiques (TAAN). Ces lignes directrices provisoires offrent des recommandations sur les utilisations prioritaires des tests de diagnostic rapide à détection d'antigène (TDR-Ag) dans des populations et des contextes spécifiques, notamment (i) pour la détection primaire des cas chez les personnes symptomatiques suspectées d'être infectées et les personnes asymptomatiques à haut risque de COVID-19, (ii) pour la recherche des contacts, (iii) pendant les enquêtes sur les épidémies et (iv) pour surveiller les tendances de l'incidence de la maladie dans les communautés. Les TDR-AG répondant aux exigences minimales de performance peuvent être utilisés en dehors des milieux cliniques et des laboratoires, y compris dans les communautés, par des opérateurs formés conformément aux instructions. Le guide fournit en outre des recommandations sur la mise en œuvre, la sélection des produits et le stockage

9 March 2022, Timely and accurate diagnostic testing for SARS-CoV-2 is an essential part of a comprehensive COVID-19 response strategy. Ag-RDTs can be performed by individuals in which they collect their own specimen, perform a simple rapid test and interpret their test result themselves at a time a...nd place of their choosing, termed COVID-19 self-testing. This interim guidance provides a new recommendation that COVID-19 self-testing, using SARS-CoV-2 Ag-RDTs, should be offered as part of SARS-CoV-2 testing services. It also includes implementation considerations that can guide decisions on whether, and how, to adopt self-testing in different contexts, including the populations being prioritized; the disease prevalence in that population; and the impact on accessibility of testing, health care services and result reporting.

Transmission of many infectious diseases depends on interactions between humans, animals, and the environment. Incorporating these complex processes in transmission dynamic models can help inform policy and disease control int...erventions. We identified 20 diseases involving environmentally persistent pathogens (ie, pathogens that survive for more than 48 h in the environment and can cause subsequent human infections), of which indirect transmission can occur from animals to humans via the environment.

Climate change, increasing population densities, and intensified globalisation in trade, travel and migration are among the most important factors shaping the 21st century. Each impacts upon population health and the risk of infectious disease, particularly those originating at the human-animal-envi...ronmental interface. The recognition that many risk drivers of infectious disease fall outside of the typical domain of the health sector creates the challenge of identifying and pursuing priorities for cross-sectoral action aimed at strengthening global health security. In response, the One Health concept has emerged, as have related initiatives addressing Planetary Health and Biodiversity and Human Health. From a public health perspective and operationally speaking, the One Health approach offers great potential, emphasising as it does cooperation and coordination between multiple sectors. Yet despite having been a focal point for discussion for over a decade, numerous challenges facing the implementation of One Health preparedness strategies remain. While some are technical, related to the requirement for innovative early warning systems or new vaccines, for example, others are institutional and cultural in nature, given the transdisciplinary nature of the topic. There have thus been calls to address One Health from multiple perspectives, from ecology to the social sciences. In order to further explore this issue and to identify priority areas for action for strengthening One Health preparedness in Europe, ECDC convened an expert consultation on 11–12 December 2017.

Infectious diseases continue to impose unpredictable burdens on global health and economies, a subject that requires constant research and updates. In this sense, the objective of the present article was to review studies on the role of wild animals as reservoirs and/or dispersers of etiological age...nts of human infectious diseases in order to compile data on the main wild animals and etiological agents involved in zoonotic outbreaks.

Dengue is the world’s most important arboviral disease in terms of number of people affected. Over the past 50 years, incidence increased 30-fold: there were approximately 390 million infections in 2010. Globalization, trade, travel,... demographic trends, and warming temperatures are associated with the recent spread of the primary vectors Aedes aegypti and Aedes albopictus and of dengue. Overall, models project that new geographic areas along the fringe of current geographic ranges for Aedes will become environmentally suitable for the mosquito’s lifecycle, and for dengue transmission. Many endemic countries where dengue is likely to spread further have underdeveloped health systems, increasing the substantial challenges of disease prevention and control. Control focuses on management of Aedes, although these efforts have typically had limited effectiveness in preventing outbreaks. New prevention and control efforts are needed to counter the potential consequences of climate change on the geographic range and incidence of dengue, including novel methods of vector control and dengue vaccines.

Climate change refers to long-term shifts in weather conditions and patterns of extreme weather events. It may lead to changes in health threat to human beings, multiplying existing health problems. This review examines the scientific e...vidences on the impact of climate change on human infectious diseases. It identifies research progress and gaps on how human society may respond to, adapt to, and prepare for the related changes. Based on a survey of related publications between 1990 and 2015, the terms used for literature selection reflect three aspects — the components of infectious diseases, climate variables, and selected infectious diseases. Humans' vulnerability to the potential health impacts by climate change is evident in literature. As an active agent, human beings may control the related health effects that may be effectively controlled through adopting proactive measures, including better understanding of the climate change patterns and of the compound disease-specific health effects, and effective allocation of technologies and resources to promote healthy lifestyles and public awareness. The following adaptation measures are recommended: 1) to go beyond empirical observations of the association between climate change and infectious diseases and develop more scientific explanations, 2) to improve the prediction of spatial–temporal process of climate change and the associated shifts in infectious diseases at various spatial and temporal scales, and 3) to establish locally effective early warning systems for the health effects of predicated climate change.
