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.

Antibiotic resistant bacteria are spreading at an alarming rate and some bacterial infections may once again be untreatable. Antibiotic resistance (ABR), conservatively calculated, causes more than 500 000 deaths every year. This number is projected to rise dramatically if radical actions are not ta...ken. Lack of effective antibiotics, diagnostics and vaccines threatens the health of millions and hampers fulfilment of several of the Sustainable Development Goals. Access to effective antibiotics should be part of every adult and child’s right to health.

Burns are a global public health problem, accounting for close to 200,000 deaths annually. The majority of these occur in low- and middle-income countries, where a number of constraints complicate the public health task of addressing burns. While the primary prevention of burns in low- and middle-in...come countries is a pressing need, the World Health Organization (WHO) also actively encourages further development of burn-care systems, including the training of health-care providers in the appropriate triage and management of people with burns.

Recent systematic reviews and meta-analysis of the impact of chemical-based mollusciciding (King et al., 2015, Sokolow et al., 2016) have concluded that regular mollusciciding is likely to contribute significantly towards elimination of schistosomiasis in high-risk areas. The WHO roadmap’s new foc...us on “transmission control, wherever possible” (WHO, 2012a) reinforces the need to promote intermediate-host snail control to prevent schistosomiasis transmission.
This operational manual is intended to facilitate the reintroduction of practices and protocols for use of molluscicides in the field in schistosomiasis control programmes. It is complemented by guidelines on the laboratory and field testing of the efficacy of molluscicides for schistosomiasis control (WHO, 2017 [in preparation]).

Whole-genome sequencing (WGS) provides a vast amount of information and the highest possible resolution for pathogen subtyping. The application of WGS for global surveillance can provide information on the early emergence and spread of AMR and further inform timely policy development on AMR control.... Sequencing data emanating from AMR surveillance may provide key information to guide the development of rapid diagnostic tools for better and more rapid characterization of AMR, and thus complement phenotypic methods. This document addresses the applications of WGS for AMR surveillance, including the benefits and limitations of current WGS technologies
