In December 2000, physicians in the Republic of the Marshall Islands reported the first known outbreak of Vibrio cholerae O1 infection (biotype El Tor, serotype Ogawa) from this country. In a matched case-control study on Ebeye Island, patients with cholera (n=53) had greater odds than persons without cholera (n=104) to have drunk adequately chlorinated water collected from a US military installation on neighboring Kwajalein Island and transported back to Ebeye (matched odds ratio [MOR], 8.0; P=.01). Transporting or storing drinking water in a water cooler with a spout and a tight-fitting lid was associated with reduced odds of illness (MOR, 0.24; P<.01), as was drinking bottled water (MOR, 0.08; P<.01), boiled water (MOR, 0.47; P=.02), or water flavored with powdered drink mixes (MOR, 0.18; P<.01). No cases of cholera were reported among Kwajalein residents. This outbreak highlights the critical importance of handling and storing drinking water safely, especially during outbreaks of gastrointestinal illness.
