In today's health matters, Cholera cases are rising threefold in the Haitian capital, Port-Au-Prince.

'Doctors Without Borders' says they've seen as many as 850 cases in a single week. It compares with about 250 cases a week more than a month ago.

The disease is relatively easy to treat if people get help in time. But, Haiti's poverty makes it difficult to find immediate medical assistance.

According to Haitian health officials, the epidemic's killed more than 6,000 people and sickened nearly half a million others.
