How many people get infected with cholera each year in america?

Few. There is the occasional case of the non-epidemic serotypes of cholera acquired usually from uncooked shellfish from the gulf of mexico. These are actually not counted as cholera. In the last few years, with the tragic outbreak of cholera affecting haiti and dr, some cases have come to the usa in travelers. There has been, additional, a smaller outbreak of cholera in cuba this year.
