Fièvres virales d'ailleurs [Viral fevers from elsewhere].

Some viruses are transmitted only in specific parts of the world and do not exist in Switzerland. However, the increase in intercontinental travels, the tendency of travelers to have activities in remote rural areas, the transportation (sometimes forbidden) of exotic animals, the climatic warming and the adaptation of viruses to new vectors produce an extension of viral diseases towards Northern countries. To improve the identification of these infections in travelers, but also in European autochthonous populations, it is necessary to know the clinical characteristics and the websites announcing the epidemics. Neurological or hemorrhagic signs should incite the clinician to suspect a viral hemorrhagic fever, diagnosis to be considered if the destination and chronology are compatible, strict isolation measures being necessary.

Small farmers of the Florida Province (Bolivia) : Reciprocity in Practice

Peasant societies are often seen by neoliberal or Marxist theorists as passive subjects of political-economic transformations occurring at a higher level, only surviving through acculturation to market requirements. By analyzing agricultural work organization in highland communities and a local system of water management called Acuerdos Reciprocos por el Agua (Reciprocal Agreements for Water), developed in 2003 by the Natura Bolivia foundation in Florida Province in Bolivia, we show that, contrary to this perception, traditional reciprocal norms still play an essential role in decision making. This suggests the agency of rural societies and the resilience of traditional reciprocity-based norms in mountain regions.
