Resumo: Chikungunya spread throughout the Dominican Republic (DR) after the first identified laboratory-confirmed cases were reported in April 2014. In June 2014, a U.S.-based service organization operating in the DR reported chikungunya-like illnesses among several staff. We assessed the incidence of chikungunya virus (CHIKV) - dengue virus (DENV) infection - illnesses - evaluated adherence to mosquito avoidance measures among volunteers/staff deployed in the DR who returned to the United States during July-August 2014. Investigation participants completed a questionnaire that collected information on demographics, medical history, self-reported illnesses, - mosquito exposures - avoidance behaviors - provided serum for CHIKV - DENV diagnostic testing by reverse transcription polymerase chain reaction - IgM enzyme-linked immunosorbent assay. Of 102 participants, 42 (41%) had evidence of recent CHIKV infection - two (2%) had evidence of recent DENV infection. Of the 41 participants with evidence of recent CHIKV infection only, 39 (95%) reported fever, 37 (90%) reported rash, - 37 (90%) reported joint pain during their assignment. All attended the organization's health trainings, - 89 (87%) sought a pretravel health consultation. Most (?95%) used insect repellent; however, only 30% applied it multiple times daily - < 5% stayed in housing with window/door screens. In sum, CHIKV infections were common among these volunteers during the 2014 chikungunya epidemic in the DR. Despite high levels of preparation, reported adherence to mosquito avoidance measures were inconsistent. Clinicians should discuss chikungunya with travelers visiting areas with ongoing CHIKV outbreaks - should consider chikungunya when diagnosing febrile illnesses in travelers returning from affected areas.
