A Southwest Florida woman who visited family in the disease-stricken Artibonite Valley of Haiti and a Haitian construction worker who lives in the eastern Dominican Republic but recently spent two weeks in Port-au-Prince became the first people to import deadly cholera.
The spread is worrying public health specialists in several countries who fear the illness could spread internationally.
The acute intestinal infection first surfaced in Haiti four weeks ago and has killed 1,110 people and hospitalized 18,382 since.
