In October 2010, a Nebraska clinician notified the state's Central District Health Department (CDHD) of a cluster of dengue-like illnesses in six of 28 missionary workers from Nebraska and Georgia who recently had returned after 7--11 days in Haiti. Infection with the mosquito-transmitted dengue virus (DENV) later was confirmed by laboratory testing in seven persons, five of whom were hospitalized...This report describes the results of that study, which indicated that 90% of those in the study had a pretravel health-care appointment, 57% sought travel advice on the Internet, and 24% used mosquito repellent several times a day...
...Thus, of the 28 travelers in this group, 21 (75%) had complete DENV laboratory testing, seven of whom (33%) were infected with DENV-1...
Review of hospital discharge summaries showed that none of those hospitalized met the WHO clinical criteria for severe dengue...
This report confirms recent DENV transmission in Haiti with an attack rate of ≥25% among a group of travelers who were in the country for 7--11 days. A similar investigation of dengue among short-term travelers to the Dominican Republic in 2008 indicated an attack rate of ≥42%, with laboratory testing limited to those with a clinical presentation consistent with dengue. Little is known about the epidemiology of dengue in Haiti. However, this report corroborates previous findings of dengue among military personnel deployed to Haiti and high DENV seroprevalence among Haitian children, indicating that DENV likely is endemic in Haiti...
