Many parasitic infections can be prevented, although not completely eliminated, through modern sanitary measures. The condition is caused by parasites that thrive in unclean water or food or that are passed along through insect bites. In developed nations, parasitic infections are far more rare than in undeveloped areas. When traveling to undeveloped areas, avoid drinking tap water. Also be careful about washing any food in tap water and using ice from unpurified sources.
