Cholera: Three Key Steps to Stopping an Outbreak

Cholera, a virulent illness that comes on quick and can be fatal mere hours after symptoms appear, kills more than 100,000 people a year.

And because nearly three-quarters of those infected with cholera don't develop symptoms, the bacteria in their fecal matter can enter water streams unmitigated and go on to sicken myriad others.

Haitian communities are, not surprisingly, experiencing a surge in cholera cases. Slums and camps for displaced persons are hotbeds for outbreaks because of poor infrastructure, overcrowding and a lack of adequate sanitation.

More than 250 people have succumbed to the illness already, as aid workers try to contain outbreaks and prevent them from reaching the Haitian capital of Port-au-Prince. So far, officials are cautiously optimistic that the multinational strategy will prove effective.
