Launching a national surveillance system after an earthquake — Haiti, 2010
Morbidity and Mortality Weekly Report
This report describes the formation and launching of the National Sentinel Site Surveillance System to monitor disease trends, detect outbreaks and characterize affected population to target relief efforts in Haiti after a 7.0-magnitude earthquake hit the country on 12 January 2010. Fifty-one hospital and clinic surveillance sites were selected to report daily counts by e-mail or telephone for 25 specified reportable conditions classified into infectious (fever of unknown cause, suspected malaria, suspected dengue fever, acute haemorrhagic fever syndrome, acute watery diarrhoea, acute bloody diarrhoea, suspected typhoid fever, acute respiratory infection, suspected measles, tuberculosis and tetanus), noninfectious (acute malnutrition, skin disorder, renal failure, pregnancy complications or third trimester without previous care, mental health or psychological health, and chronic diseases not accounted for in other conditions), and injuries (trauma, fracture, cerebral concussion from head injury, laceration from weapon or dagger injury, burns, wounds, crush injury syndrome and amputation). A total of 42 361 persons had a reportable condition during 25 January-24 April 2010; of these, 54.5% were female and 32.6% were aged <5 years. The 3 most frequently reported specified conditions were acute respiratory infection (16.3%), suspected malaria (10.3%) and fever of unknown cause (10.0%). Injuries accounted for 12.0% of reported conditions. No epidemics or disease clusters were detected and the number of reports decreased over time.
