How much worse can the situation get in Haiti? BBC:
Five cases of cholera have been detected in Haiti's capital, Port-au-Prince, the UN says, amid an outbreak that has killed more than 200 people.
UN spokeswoman Imogen Wall told the Reuters news agency the patients had been quickly diagnosed and isolated.
She said they had been infected in the main outbreak zone - the Artibonite region - and had subsequently travelled to the capital, where they fell ill.
This meant Port-au-Prince was "not a new location of infection", she noted.
