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:
“Trade and commerce, if they were not made of India-rubber, would never manage to bounce over the obstacles which legislators are continually putting in their way; and, if one were to judge these men wholly by the effects of their actions and not partly by their intentions, they would deserve to be classed and punished with those mischievous persons who put obstructions on the railroads.”
—Henry David Thoreau (1817–1862)

“Henceforth I whimper no more, postpone no more, need nothing,
Done with indoor complaints, libraries, querulous criticisms,
Strong and content I travel the open road.”
—Walt Whitman (1819–1892)
