En 2015, 26 % des décès de 5,9 millions d'enfants de moins de cinq ans auraient pu être évités si les facteurs de risque
environnementaux avaient été pris en compte – cette possibilité manquée de sauver des vies est révoltante. La période prénatale

naissance prématurée et d'autres complications, et accroître le risque de maladies chroniques, et notamment de troubles respiratoires, de maladie cardiovasculaire et de cancer. L'environnement est donc un facteur majeur de la santé des enfants et offre d'importantes possibilités d'amélioration dont les effets se manifestent dans toutes les régions du monde.

The Infection Prevention and Control (IPC) Legal Framework comes before the Specialized Technical Committee on Health and Drug Control for adoption and endorsement. The IPC Legal Framework is designed to guide Member States in the review and strengthening of laws and policies that support IPC at bot...h the national level and in healthcare facilities. In developing this IPC Legal Framework, the Africa Centres for Disease Control and Prevention (Africa CDC)

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.

Malaria is an important disease that has a global distribution and significant health burden. The spatial limits of its distribution and seasonal activity are sensitive to climate factors, as well as the local capacity to control the disease. Malaria is also ...one of the few health outcomes that has been modeled by more than one research group and can therefore facilitate the first model intercomparison for health impacts under a future with climate change. We used bias-corrected temperature and rainfall simulations from the Coupled Model Intercomparison Project Phase 5 climate models to compare the metrics of five statistical and dynamical malaria impact models for three future time periods (2030s, 2050s, and 2080s). We evaluated three malaria outcome metrics at global and regional levels: climate suitability, additional population at risk and additional person-months at risk across the model outputs. The malaria projections were based on five different global climate models, each run under four emission scenarios (Representative Concentration Pathways, RCPs) and a single population projection. We also investigated the modeling uncertainty associated with future projections of populations at risk for malaria owing to climate change. Our findings show an overall global net increase in climate suitability and a net increase in the population at risk, but with large uncertainties. The model outputs indicate a net increase in the annual person-months at risk when comparing from RCP2.6 to RCP8.5 from the 2050s to the 2080s. The malaria outcome metrics were highly sensitive to the choice of malaria impact model, especially over the epidemic fringes of the malaria distribution.

Dengue is a mosquito-borne viral disease that occurs mainly in the tropics and subtropics but has a high potential to spread to new areas. Dengue infections are climate sensitive, so it is important to better understand how changing climate factors affect the potential for geographic spread and futu...re dengue epidemics. Vectorial capacity (VC) describes a vector's propensity to transmit dengue taking into account human, virus, and vector interactions. VC is highly temperature dependent, but most dengue models only take mean temperature values into account. Recent evidence shows that diurnal temperature range (DTR) plays an important role in influencing the behavior of the primary dengue vector Aedes aegypti. In this study, we used relative VC to estimate dengue epidemic potential (DEP) based on the temperature and DTR dependence of the parameters of A. aegypti. We found a strong temperature dependence of DEP; it peaked at a mean temperature of 29.3°C when DTR was 0°C and at 20°C when DTR was 20°C. Increasing average temperatures up to 29°C led to an increased DEP, but temperatures above 29°C reduced DEP. In tropical areas where the mean temperatures are close to 29°C, a small DTR increased DEP while a large DTR reduced it. In cold to temperate or extremely hot climates where the mean temperatures are far from 29°C, increasing DTR was associated with increasing DEP. Incorporating these findings using historical and predicted temperature and DTR over a two hundred year period (1901-2099), we found an increasing trend of global DEP in temperate regions. Small increases in DEP were observed over the last 100 years and large increases are expected by the end of this century in temperate Northern Hemisphere regions using climate change projections. These findings illustrate the importance of including DTR when mapping DEP based on VC.

This document provides guidance on interventions to prevent vaccine-preventable disease outbreaks in the context of mass population movement resulting from the ongoing crisis in Ukraine.
The Executive Board at its 150th session noted an earlier version of this report.1 The present report provides an update on the implementation of the Strategic Action Plan on Polio Transition (2018–2023)2 at the start of 2022, within the context of the coronavirus disease (COVID-19) pandemic.
In 2009, WHO’s Second International Conference on Buruli Ulcer Control and Research resolved to strengthen the capacity of national laboratories to confirm cases of the disease, but advised that “efforts are still needed to develop simple diagnostic tools usable in the field as well as disabilit...y prevention methods”.
In 2013, WHO and the Foundation for Innovative New Diagnostics convened a meeting of Buruli ulcer experts in Geneva, Switzerland (9) at which two priority unmet needs in diagnosis were identified:
a diagnostic test for early detection of Buruli ulcer in symptomatic patients with sufficient positive predictive value to put patients on appropriate treatment; and
a screening test at the primary health care or community level for symptomatic patients with ulcer

May 9, 2022.Since the onset of the COVID-19 pandemic, a large number of clinical trials have been planned and developed to assess the effectiveness and safety of various interventions that could prevent hospitalizations and progression to severe disease in people infected with SARS-CoV-2. Currently,... the WHO and the PAHO recommend the use of corticosteroids, tocilizumab, baricitinib, and casirivimab e imdevimab (the latter in seronegative COVID-19 patients) and propose the use of sotrovimab, casirivimab/imdevimab, and molnupiravir in patients with non-severe illness who are at high risk for complications
