In January 2010, Haiti suffered a devastating earthquake that killed more than 200,000 people, left millions homeless, and significantly damaged the country's already fragile infrastructure, including its health system. In this Director's Briefing video, CDC Director Dr. Tom Frieden talks about how CDC, CDC Foundation (www.cdcfoundation.org), and other critical partners are helping Haiti recover and rebuild. New laboratories and office space are allowing critical public health work to continue, protecting people in Haiti and abroad from health threats. After all, diseases know no borders.
