A medida que las Américas experimentan un profundo cambio demográfico y hay más personas de 65 años que menores de 5 años, es crucial reconocer que los programas nacionales de inmunización deben rediseñarse para garantizar una protección integral a las personas a lo largo de toda su vida. Al... adoptar un enfoque de curso de vida para la inmunización, los programas de vacunación pueden adaptarse para cerrar las brechas de inmunidad en las distintas etapas de la vida. El enfoque del curso de vida prevé el establecimiento de múltiples estrategias para reducir las oportunidades perdidas de vacunación según el grupo de edad. El presente documento técnico explica los conceptos clave del enfoque de curso de vida en la inmunización mediante la vacunación, así como los mecanismos biológicos subyacentes que requieren la aplicación de diferentes vacunas en diversas etapas de la vida según los cambios en el sistema inmunitario y en la situación epidemiológica de la comunidad

As the Americas undergo profound demographic change and there are more persons aged 65 years or older than children younger than 5 years, it is crucial to recognize that national immunization programs must be redesigned to ensure comprehensive protection for individuals across the lifespan. By adopt...ing a life course approach (LCA) to immunization, vaccination programs can be tailored to close immunity gaps at different stages of life. The life course approach foresees the establishment of multiple strategies to reduce missed opportunities for vaccination according to age group. This technical document explains the key concepts of the LCA with a focus on immunization by vaccination, as well as the underlying biological mechanisms that require the application different vaccines at different life stages according to changes to the immune system and in the epidemiological situation of a community.

Mortality due to enteric infections is projected to increase because of global warming; however, the different temperature sensitivities of major enteric pathogens have not yet been considered in projections on a global scale. We aimed to project global temperature-attributable enteric infection mor...tality under various future scenarios of sociodemographic development and climate change.

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.

Using infectious diseases sensitive to climate as indicators of climate change helps stimulate and inform public health responses

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.

Dieses Kurzdossier konzentriert sich besonders auf den Zusammenhang zwischen zwei übertragbaren
tropischen Armutserkrankungen – dem Wurmbefall des Darms durch Geohelminthen wie Spul-,
Peitschen- und Hakenwürmer sowie der Schistosomiasis (Bilharziose). Es zeigt Möglichkeiten zu
deren Bekämpf...ung auf und appelliert an internationale Entwicklungspartner, im Rahmen ihrer Gesundheits-
und Ernährungsprogramme regelmäßige Entwurmungsbehandlungen für alle, die eine
solche Behandlung benötigen, zugänglich zu machen. So können die Lebensbedingungen der Armen
nachhaltig verbessert werden.
