The number of U.S. cholera cases has jumped markedly in the past five years, with most brought in by travelers from foreign countries and resistant to antibiotics, federal researchers say.
But “the risk of cholera to the individual traveler remains extremely low,” the researchers said in today’s The Journal of the American Medical Association.
From 1992 through 1994, 160 cases of cholera were reported to the Centers for Disease Control and Prevention. That was up significantly from the 136 cases in the 27 previous years, from 1965 through 1991.
Half the 1992-94 cases resulted from outbreaks affecting 75 passengers on an airplane from Latin America and five passengers on a cruise ship in southeast Asia, the researchers said.
