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.

Applicable to both IDP and refugee scenarios, the Toolkit incorporates a wide range of relevant information on managing displaced populations living in communal settings (collective centres, spontaneous sites, established camps, etc.). Large scale displacements caused by recent conflict and natural ...disaster events have created a high demand for the Toolkit, which has proven an invaluable resource for field practitioners, government actors and displaced populations since its original release in 2004.

La promotion de la santé et la prévention des maladies nécessitent une action multisectorielle qui renforce les environnements favorables à la santé et oriente les comportements. Au niveau des cantons et des communes, de nombreuses politiques, telles
la protection de la jeunesse, la promotion ...de la santé à l’école, la promotion de la santé et de la sécurité au travail, l’action sociale, le soutien au logement, la promotion de l’intégration, l’aménagement du territoire, la gestion de la mobilité ou la protection
de l’environnement sont des leviers très efficaces pour améliorer l’état de santé de la population.
L’argumentaire «Promouvoir la santé et prévenir les maladies» a pour objectif d’expliquer les enjeux et
d’inciter les personnes actives dans ces divers domaines à intégrer la promotion de la santé dans leurs activités et projets. Cela exige de leur mettre à disposition des informations actuelles et facilement compréhensibles

Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are... limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.

WHO published guidance for clinicians and health care decision-makers on the use of corticosteroids in patients with COVID-19.
We recommend systemic corticosteroids for the treatment of patients with severe and critical COVID-19. We suggest not to use corticosteroids in the treatment of patients ...with non-severe COVID-19 as the treatment brought no benefits, and could even prove harmful. Treatment should be under supervision of a clinician.
Corticosteroids are listed in the WHO model list of essential medicines, readily available globally at a low cost. WHO encourages countries to maintain sufficient stocks of corticosteroids to treat COVID-19 and the other disease for which they are effective, while not maintaining excessive stocks which could deny other countries access.

The purpose of the survey is to identify the level of preparedness required by a health-care facility to be able to continue operating during, or following a conflict-related security event.
The survey method provides a measure of the security and preparedness of a given health facility in it...s specific context. Such a measure offers evidence-based guidance to assess whether urgent action needs to be taken and, if so, in what form.
Decision-makers can prioritize the most effective actions to mitigate specific risks and, eventually, will be able to rank the importance of needs faced by multiple facilities.
The survey covers three modules: the hazards affecting the facility, the current management procedures in place and the state of the physical infrastructure. Each of these modules is further divided into categories, and each category contains the questions – or indicators ‒ that cover the actual issues addressed in the survey. A detailed description of each indicator is provided in this manual.

The Guidelines for essential trauma care seek to set achievable standards for trauma treatment services which could realistically be made available to almost every injured person in the world. They then seek to define the resources that would be necessary to assure such care.

A Joint Statement by the World Health Organization and the United Nations Children’s Fund.
On 15–16 December 2020, WHO and the Medicines for Malaria Venture co-convened a technical consultation to consider the preferred product characteristics (PPCs) for drugs used in malaria chemoprevention. The main goal of the technical consultation was to agree on the most important PPCs for drugs t...o protect populations from malaria (chemoprevention), while considering relevant measures of efficacy and the safety data needed to support WHO policy recommendations.

The COVID-19 pandemic’s immediate costs, measured in lives lost and damaged, have been appalling and continue to rise. In addition, its effects on individuals’ livelihoods and economies around the world have been deep and are likely to be long lasting. While saving lives was the near-exclusive f...ocus during the first phase of the crisis, governments are now trying to strike a delicate balance between preventing further economic damage by reopening parts of their economies, while managing the obvious health risks of doing so.
In the international mobility and migration arenas—policy areas enormously affected by the health and economic effects of the pandemic—this reflection considers both how these fields have fared thus far and the challenges that lay ahead
