Almost a year after a nationwide outbreak, the spread of the waterborne disease cholera is showing no signs of ending in Haiti.

So far, more than 6,000 have died and about 400,000 have been infected, with people often relying on rivers as their main source of water for drinking, bathing and washing.

Epidemiologists say the number of infections has spiked recently in many provinces.

With the hurricane season on the way, aid workers on the Caribbean island are calling for more donations to prevent it from spreading further.
