Haiti cholera outbreak: Attempts to keep camps healthy

Aid efforts are being stepped up to try to stem a cholera outbreak in Haiti. More than 250 people have died since the outbreak in the north of the country.

The first cases have now been detected in the capital Port-au-Prince, where more than a million people live in makeshift camps since the earthquake in January.

Health officials say the number of new cases is now falling.
