CBN's Operation Blessing International is taking steps to prevent another cholera outbreak from spreading in Haiti in the wake of Hurricane Sandy.

Flooding across the tiny island nation sent many residents still displaced by the 2010 earthquake scrambling for shelter.

"As is always the case in Haiti, water kills far more people than wind," Operation Blessing President Bill Horan said.

Water supplies are expected to take a hard hit from Sandy's flooding rains.

"Cholera is the silent killer and will spike in coming days due to flooded latrines and vulnerable population," Horan predicted.

The aid group is working around the clock to produce chlorine to help purify those supplies.

Water purification in Haiti has been a major focus of Operation Blessing since the 2010 earthquake devastated the country. 

Haiti is currently home to the world's largest cholera epidemic. In the last two years over 7,000 Haitians have died from the disease.
