Japanese Encephalitis: Assessing disease risk due to landscape factors at multiple scales

Japanese Encephalitis is a mosquito-borne disease and is the leading cause of viral encephalitis in Asia. In many Asian countries, the geographical distribution of JE is dependent on a variety of human-environment interactions that can be conceptualized as a complex social-ecological system. The JE transmission cycle is influenced by a few primary human-landscape factors; the abundance and the spatial configuration of rice paddy fields (which provide habitat for the vector), the distribution of pig farms (which position the virus\u27 amplifying host), and the location of a susceptible human population. Our models integrate population dynamics, landscape characteristics, and weather variables that influence the spatiotemporal risk of contracting the JE virus. At a geographically small scale, we highlight regions within the geographic distribution of the disease that are of high-risk in the near future. An individual-level model was also developed to assess disease risk at a larger geographic scale. Model output reproduced the spatial and temporal dynamics of Japanese Surveillance data obtained from the World Health Organization. Such a model can be used to assess various scenarios that examine the spatial epidemiology of Japanese Encephalitis

UV Index monitoring in Europe

The UV Index was established more than 20 years ago as a tool for sun protection and health care. Shortly after its introduction, UV Index monitoring started in several countries either by newly acquired instruments or by converting measurements from existing instruments into the UV Index. The number of stations and networks has increased over the years. Currently, 160 stations in 25 European countries deliver online values to the public via the Internet. In this paper an overview of these UV Index monitoring sites in Europe is given. The overview includes instruments as well as quality assurance and quality control procedures. Furthermore, some examples are given about how UV Index values are presented to the public. Through these efforts, 57% of the European population is supplied with high quality information, enabling them to adapt behaviour. Although health care, including skin cancer prevention, is costeffective, a proportion of the European population still doesn’t have access to UV Index information
