On January 12, 2010, an earthquake devastated Haiti's infrastructure, killing an estimated 230,000 persons and displacing more than 1.5 million. Ten months later, Haiti experienced the beginning of the largest cholera epidemic ever reported in a single country. Immediately after the earthquake and at the start of the cholera epidemic, health priorities in Haiti included improvement of surveillance and laboratory capacity for addressing public health threats in the general population and targeted surveillance and provision of improved water and sanitation in camps for internally displaced persons. As part of a multi-sector, post-earthquake response in collaboration with the Government of Haiti and others, CDC focused on supporting the recovery, expansion, or establishment of several key health programs. This update reports progress in selected health programs, services, and systems in Haiti as of the end of 2014.
