With deaths from the cholera outbreak in Haiti having climbed above 300, health experts are warning the epidemic is far from over.
Close to 5,000 people have reportedly been infected with the disease so far, and officials say it will be years before it's eradicated.
"It is the most feared disease in disaster relief because it spreads extremely quickly and is lethal. People can die in as short as four hours," Gerald Martone, director of humanitarian affairs for The International Rescue Committee, told CNN.
"In addition to preventing the spread of this disease," Martone explained, "you have to aggressively treat the people affected, as you only have a few hours before someone can die. This challenge will overwhelm the Haiti health system."
As health clinics stretch beyond capacity with cholera victims, Operation Blessing International is in the area providing on-going relief to those suffering from the illness.
Volunteers worked this week with a medical team from Saint Luc Hospital. They provided emergency medical care to people in the village of Dauphin.
Operation Blessing is also distributing Lifesaver jerrycans to villages that desperately need safe clean water. The jerrycans use a highly advanced filtration system to purify any type of water.

In addition, the charity aid organization is working to airlift a water purification system to the town of Grande Saline.
The roads in the area of the town are impassible due to heavy flooding, and many people have died there from cholera-related illnesses.
