Nurses examine a child suffering cholera symptoms at a Doctors Without Borders cholera clinic in Saint-Marc on Saturday. A new network of cholera-treatment centers staffed by Haitian doctors and nurses, nongovernmental organizations and international volunteers has made it easier for victims to get oral and intravenous rehydration. The disease is relatively easy to treat if caught in time. (Associated Press)
