ST. MARC, Haiti (AP) - Cases of cholera are popping up in more places outside the rural valley in central Haiti where the outbreak began.
      
Authorities have now confirmed more than 200 deaths and more than 2,000 people have fallen ill in Haiti's worst health crisis since a a devastating January earthquake.

The cholera outbreak started in a rural valley in the central part of the country, but has now spread to locations closer to the capital where hundreds of thousands of earthquake survivors are living in squalid camps.
      
Officials say the sick include 50 inmates at a prison just north of the capital, Port-au-Prince.
      
Cholera is a bacterial infection spread through contaminated water. It causes severe diarrhea and vomiting that can lead to death within hours.
      
Cholera wasn't present in Haiti before the earthquake, but experts have warned since then that conditions are ripe for disease.
