Kenya's Nyanza Province is experiencing a major cholera outbreak. More than 130 people have died since the first case was reported 3 months ago and 30 food houses and two major markets have been closed by health authorities in the provincial capital, Kisumu. The provincial medical officer has reported that more than 2500 people have thus far been hospitalized and 25,000 have been given drugs. The epidemic has reached a critical stage and local communities have been advised to follow high hygienic standards. Cases are suspected in the neighboring Rift Valley province. Mozambique's Ministry of Health has reported 346 cases of cholera with 14 deaths through September. The cases have mainly been in five areas of Maputo city and no case has been reported outside of the city. As Zambia's rainy season begins, people fear the return of cholera, a growing, recurrent problem during the season for the past 8 years. Health authorities fear the disease will become endemic unless water treatment practices are improved. The Tropical Diseases and Research Center (TDRC) in Ndola recently organized a 1-day symposium on epidemic diarrhea, cholera, and dysentery in Zambia to stimulate discussion of disease prevention methods.
