Effects of Travel
"Travellers" are defined as coming from non-endemic areas and exposed for a limited time, whereupon they return to a non-endemic site. Schistosomiasis (in particular genital schistosomiasis) has been neglected in travellers, despite the risk of infection with certain types of increasingly-common travels such as rafting and other forms of ecotourism. 18% of asymptomatic travellers to Africa, exposed to freshwater and subsequently screened at the Hospital for Tropical Diseases in London, were found to have schistosomiasis. Katayama fever, fatigue and dysuria are the commonest presentations in symptomatic travellers. There are, however, a few case reports where genital schistosomiasis has been found years after a reasonably short exposure.
The manifestations of schistosomal disease in non-genital organs, immunological considerations, immunodiagnosis, S. haematobium parasite adaptation, snail control and schistosomiasis’ relationship to cancer are beyond the scope of this article. Although S. mansoni, S. intercalatum, S. japonicum and S. matthei may affect the genital organs and the magnitude of the problem is not known.

Famous quotes containing the words effects of, effects and/or travel:
“The hippie is the scion of surplus value. The dropout can only claim sanctity in a society which offers something to be dropped out of—career, ambition, conspicuous consumption. The effects of hippie sanctimony can only be felt in the context of others who plunder his lifestyle for what they find good or profitable, a process known as rip-off by the hippie, who will not see how savagely he has pillaged intricate and demanding civilizations for his own parodic lifestyle.”
—Germaine Greer (b. 1939)
“Corporate America will likely be motivated to support child care when it can be shown to have positive effects on that which management is concerned about—recruitment, retention and productivity. Indeed, employers relate to child care as a way to provide growth fostering environments for young managers.”
—Dana E. Friedman (20th century)
“I never travel without my diary. One should always have something sensational to read in the train.”
—Oscar Wilde (1854–1900)
