Saturday marks three years since a magnitude 7.0 earthquake hit the impoverished Caribbean island nation of Haiti. The quake caused tremendous damage in some of the country's major cities, including the capital of Port-Au-Prince.
The Haitian government estimates that more than 300,000 people died, while hundreds of thousands more were left injured and homeless. The tragedy generated a huge humanitarian response from the outside world.
Many countries pledged millions of dollars in aid and dispatched hundreds of rescue and medical teams. Among those who went to help was Dr. Megan Coffee, an infectious disease specialist who left Berkeley, California for Haiti only days after the quake.
She's been working there since, in the State General Hospital in Port-Au-Prince, and joins the show to give us an update on the progress and the work that still needs to be done.
