Ebola Deeply is an online web portal and news site designed to provide accurate and timely information about the Ebola health crisis, with an emphasis on providing context and countering misinformation. Launched in October 2014, this digital media project involves a team of freelance journalists and... technologists who feature a mix of original articles, op-eds, and content from the Associated Press and other news organisations. A key feature of the site is the Ebola Files section, a collection of text and interactive materials covering basic information, the history of the Ebola virus, scientific perspectives, and stories about survivors. There is also an interactive map of recent cases and death rates, a timeline of events, and videos

A companion to the Child Friendly Schools Manual
WASH in Schools aims to improve the health and learning performance of school-aged children – and, by extension, that of their families – by reducing the incidence of water and sanitation-related diseases. Every child friendly school r...equires appropriate WASH initiatives that keep the school environment clean and free of smells and inhibit the transmission of harmful bacteria, viruses and parasites.

In the area of nutrition and HIV, children deserve special attention because of their additional needs to ensure growth and development and their dependency on adults for adequate care. It was therefore proposed to first develop guidelines for children and thereafter consider a similar approach for... other specific groups.
The content of these guidelines acknowledges that wasting and undernutrition in HIV-infected children reflect a series of failures within the health system, the home and community and not just a biological process related to virus and host interactions. In trying to protect the nutritional well-being or reverse the undernutrition experienced by infected children, issues of food insecurity, food quantity and quality as well as absorption and digestion of nutrients are considered. Interventions are proposed that are practical and feasible in resource-poor settings and offer a prospect for clinical improvement.
The guidelines do not cover the feeding of infants 0 to 6 months old, because the specialised care in this age group is already addressed in other WHO guidelines and documents.

The report focuses on antibacterial resistance (ABR) in common bacterial pathogens. There is a major gap in knowledge about the magnitude of this problem. Antimicrobial resistance (AMR) threatens the effective revention and treatment of an ever-increasing range of infections caused by bacteria, para...sites, viruses and fungi. This WHO report, produced in collaboration with Member States and other partners, provides for the first time, as accurate a picture as is presently possible of the magnitude of AMR and the current state of surveillance globally. It examines the information on AMR, in particular antibacterial resistance (ABR), at country level worldwide.

le Sénégal continue d’être confronté à une crise alimentaire et nutritionnelle qui touche particulièrement le nord et l’est du pays. Selon les estimations faites en novembre 20151, plus de 2,4 millions de personnes sont en insécurité alimentaire (soit 17% de la population), dont 220 461 ...seront en crise pendant la période de soudure 20162. le nombre d’enfants en situation de malnutrition aiguë pourrait être de plus de 407 500 en 2016, parmi lesquels plus de 86 000 en sévère3. les chocs climatiques tels que la sécheresse et le retard de démarrage de la saison pluvieuse ont affecté le nord du pays alors que dans d’autres zones les inondations ont affecté plus de 60 000 personnes4. l’épidémie de la maladie à virus Ebola (MVE) qui a sévi aux portes du pays a montré qu’un renforcement du système de surveillance épidémiologique ainsi que le renforcement des structures de santé sont requis.

n light of the potential risk posed by SARS-CoV-2 variants, in January 2021 WHO organized an ad hoc consultation to discuss the development of an R&D agenda in response to existing and emerging SARS-CoV-2 variants.
The key objectives were to identify the critical research questions related to var...iants and agree on a research approach to address them. Six breakout groups covered a range of specific issues related to COVID-19 variants: Epidemiology and mathematical modelling; evolutionary biology; animal models; assays and diagnostics; clinical management and therapeutics; and vaccines.
This report is a summary of presentations and panel discussions.

What do we know about Omicron variant so far? WHO's Dr Maria Van Kerkhove updates on the transmissibility, severity, symptoms and ways to protect yourself in Science in 5.
If Omicron is less severe, why are people ending up in the hospital and dying from it? Is it true that everyone will eventually get Omicron? Why is it important to reduce transmission? WHO's Dr Maria Van Kerkhove explains in Science in 5.
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.
