JOHANNESBURG, South Africa (CNN) -- The political crisis that has gripped Zimbabwe for nearly a year may be drawing to an end, but a deadly cholera outbreak there is only getting worse.

Zimbabweans walk through mounds of garbage. Lack of sanitation and clean water make cholera spread.
The newly formed cabinet of Zimbabwe's unity government met for the first time Tuesday, the same day that Medecins Sans Frontieres (Doctors Without Borders) released a report warning that the epidemic shows no signs of slowing.
The outbreak -- one of the world's largest, according to the World Health Organization (WHO) -- is only getting worse, and could be a stepping-stone to other epidemics and health crises, international agencies say.
