the northern bolivian altiplano: a region highly endemic for human fascioliasis.the worldwide importance of human infection by fasciola hepatica has been recognized in recent years. the endemic region between lake titicaca and the valley of la paz, bolivia, at 3800-4100 m altitude, presents the highest prevalences and intensities recorded. large geographical studies involving lymnaea truncatula snails (malacological, physico-chemical, and botanic studies of 59, 28 and 30 water bodies, respectively, inhabited by lymnaeids; environmental mean temperature studies covering a 40 ...199910444322
high endemicity of human fascioliasis between lake titicaca and la paz valley, bolivia.over a 6-year period, an epidemiological study of human infection by fasciola hepatica in the northern bolivian altiplano was carried out. prevalences and intensities were analysed from coprological results obtained in 31 surveys performed in 24 localities and proved to be the highest known so far. the global prevalence was 15.4%, with local prevalences ranging from 0% to 68.2%. significant differences between prevalence rates were detected and the highest prevalences were in subjects aged < 20 ...199910450437
endemic human fasciolosis in the bolivian altiplano.fasciolosis, caused by trematodes of the genus fasciola, is an emerging disease of humans. one of the highest levels of human fasciolosis hepatica is found amongst the indigenous aymaran people of the northern bolivian altiplano. a meta-analysis of epidemiological surveys from 38 communities in the region demonstrates that fasciolosis has been endemic in the region since at least 1984 and is a zoonosis of rural communities. human and bovine fasciolosis is associated with the communities lying in ...200717064455
