Wednesday marks the one-year anniversary of the Haitian earthquake.
The magnitude 7.0 tremor was the worst to hit the region in more than two centuries, killing over 200,000 people.
Today, more than a million Haitians are still living in tents and improvised shelters, without access to clean water and sanitation facilities.
Washington University professor Lora Iannotti was in Haiti on the day the earthquake struck. She has returned several times since then to continue her research in nutrition and public health.
Before going back to Haiti again last week, Iannotti spoke with St. Louis Public Radio’s Véronique LaCapra about health conditions in this struggling Caribbean nation.
