Haiti: Cholera confirmed in Port-au-Prince
Doctors are treating 73 people for the disease, amid fears that it could spread across the quake-hit city.
Meanwhile, the Pan American Health Organisation (Paho) says it expects tens of thousands more Haitians to catch cholera in the next few years.
The health ministry says so far 583 people have died in the epidemic.
Dozens of suspected cases are also being investigated in Port-au-Prince, which has feared an outbreak since October.
Across the country, more than 9,000 people are being treated for symptoms of the disease, the health ministry said on Tuesday.
Health minister Ariel Henry said that a sizeable outbreak in Port-au-Prince now appeared likely.
"It's coming," Mr Henry told the AFP news agency; Kazinform cites BBC.
