Earlier this year, epidemiologists from the Centers for Disease Control
and Prevention (CDC) found a silver lining in the midst of a cholera outbreak
they were investigating in Zambia's capital city, Lusaka. They discovered
that up to 25% of the city's households use a low-tech, low-cost method to
disinfect and safely store water for drinking, bathing, food preparation,
"That's a great success—a large segment of the population is using
this preventive measure," says Pavani Kalluri, MD, a medical epidemiologist
at the CDC, as she discuses the Safe Water System (SWS).
