Americans Warned About Cholera Risk in Cuba

American travelers to Cuba should avoid street food and under- or uncooked dishes such as ceviche to reduce their risk of contracting cholera, says a U.S. government advisory issued Tuesday.

Several foreigners -- an Italian, two Venezuelans and two Chileans -- who visited Cuba were sickened by cholera in late July and early August, according to the Pan American Health Organization, the Associated Press reported.
