Emerging infectious diseases poses a great future threat, not only to humans but also to domestic animals and wildlife. Even though the majority of these infections only cause minor health problems, the relatively recent emergence of HIV clearly illustrates that the next major human pandemic may surface at any time. Regardless of what the name indicates, most emerging human pathogens are not believed to be recently evolved, but to have existed previously in the natural environment. Most emerging pathogens are zoonotic, i.e. able to infect animals besides humans.

Japanese encephalitis virus (JEV) is one of the leading causes of acute encephalitis in humans. The virus is spread by mosquitoes, mainly belonging to the Culex species. The main reservoirs are considered to be birds and pigs, with pigs constituting the most important reservoir in regard to human infection. During the last few decades the production of pork has increased significantly in Vietnam. With 90% of pigs being kept in households owning 10 pigs or less, pigs are widely spread across most parts of the country.

A distributed hydrological rainfall-runoff model has been developed using a GIS integrated with a dynamic programming module (PCRaster). The model has been developed within the framework of the EU-project TWINBAS at IVL Swedish Environmental Research Institute, and is intended for use in WATSHMAN ? a tool for watershed management developed at IVL. The model simulates runoff from a catchment based on daily mean values of temperature and precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model.

Middle East respiratory syndrome coronavirus (MERS-CoV) är ett virus som först observerades hos en patient år 2012 på ett sjukhus i Saudiarabien. Viruset orsakar luftvägssymptom och ibland gastrointestinala symptom. Dödligheten hos människa är över 30%. Eftersom tidigare erfarenhet har visat att nya coronavirus ofta har sitt ursprung i en djurpopulation har många studier gjorts för att undersöka spridningen av MERS-CoV och förekomsten av en eller flera reservoirer. Denna litteraturstudie har som mål att undersöka vilka bevis det finns för dromedarens roll i smittspridningen av MERS-CoV. Då flera seroepidemiologiska studier gjorts som visar att MERS-CoV eller ett nära besläktat virus har cirkulerat i dromedarpopulationen i över 20 år har man gått vidare och undersökt bl.a.

The travelling sector is expanding worldwide, which puts all destinations under pressure to have a functioning social system and good resources to manage the problems and take advantage of the opportunities that the tourism sector can offer a community. The area around Kisumu in Kenya, like much of Africa, tourism can simultaneously ensure a stable financial future while it removes, as a result of a growing population, more and more of the scenery that many tourists want to experience. Responsible travel to natural areas that promotes conservation of the environment and improves the welfare of local people is what defines ecotourism. A concept that implies a closed cycle, where visitor?s needs are met in balance with what can be given back, without risking creating imbalances in society. Along the coast of Lake Victoria, valuable papyrus wetlands provide Kisumu vital ecosystem services such as water purification, climate adaptation while it also serves as a reservoir for biodiversity.
