A dengue fever outbreak has plagued Rio de Janeiro since January 2002. Dengue fever is a mosquito-borne disease. The elimination of standing water, which is a breeding ground for the mosquitoes, is a primary defense against mosquito-borne diseases like dengue. Removing such water remains a difficult problem in many urban regions.
