Recent clonal origin of cholera in Haiti

Emerg Infect Dis. 2011 Apr;17(4):699-701. doi: 10.3201/eid1704.101973.


Altered El Tor Vibrio cholerae O1, with classical cholera toxin B gene, was isolated from 16 patients with severe diarrhea at St. Mark's Hospital, Arbonite, Haiti, <3 weeks after onset of the current cholera epidemic. Variable-number tandem-repeat typing of 187 isolates showed minimal diversity, consistent with a point source for the epidemic.
