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.

A national overview with a case study from Tanahun district. The overall aims of this study are (1) to assess the extent to which social protection systems in Nepal address the needs of people with disabilities; and (2) to identify and document elements of good practice, as well as challenges, in th...e design and delivery of social protection for people with disabilities. As most social protection programmes in Nepal are targeted to various groups considered to be a high risk of poverty or marginalisation (e.g. orphans, widows), the research mainly focuses on disability-specific schemes, as they are relevant to a higher proportion of people with disabilities.

The neglected zoonotic diseases (NZDs) have been all but eradicated in wealthier countries, but remain major causes of ill-health and mortality across Africa, Asia, and Latin America. This neglect is, in part, a conse...quence of under-reporting, resulting in an underestimation of their global burden that downgrades their relevance to policy-makers and funding agencies. Increasing awareness about the causes of NZDs and how they can be prevented could reduce the incidence of many endemic zoonoses.

Background: For some years, non-governmental organisations (NGOs) and civil society have
become increasingly involved in the fight against the HIV/AIDS pandemic in Africa. But even
though their role is well appreciated, the...ir actions are perceived as ineffective because of a lack
of monitoring and evaluation capacity.
Objective: This paper aims to describe local HIV/AIDS NGOs’ involvement in evaluation and
the characteristics of this involvement.
