Cholera Spreads To Port-au-Prince

Health officials have confirmed that a 3-year-old boy from a Port-au-Prince tent city has contracted cholera. The finding is the first clear sign that Haiti's growing epidemic has spread from outlying areas to the country's crowded capital. In Port-au-Prince, nearly half of the population is still living in tents after the January 12th earthquake. We get an update from Haiti with the BBC's Laura Trevelyan, who tells us about efforts to contain the outbreak that's already killed more than 500.
