Every five minutes a child dies as the result of violence, according to a ground-breaking report from Unicef UK. The report reveals that the vast majority of children are killed outside warzones and that physical, sexual and emotional abuse is widespread with millions of children unsafe in their hom...es, schools and communities. Some 345 children could die from violence each day in the next year, unless governments act.
The report also finds that:
(1) Children who are victims of violence have brain activity similar to soldiers exposed to combat;
(2) A third of children who are victims of violence are likely to develop long-lasting symptoms of post-traumatic stress disorder;
(3) Those living in poverty are more likely to be victims of violence, wherever they live in the world;
(4) Over 7% of child deaths due to violence each day are the result of interpersonal violence, rather than conflict.

What are the political, economic, social and security implications of the Ebola crisis, with a particular focus on Sierra Leone?
Public Health is the science field dedicated to promoting health and well-being, and preventing disease within the human population to ultimately increase the quality of our livelihood and life span. Public Health does not focus on individual patients or diseases, but rather a given population and ...health system. The discipline is community-centered in its interventions and seeks to improve the health status of whole populations...

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.
