International audience. Chikungunya virus (CHIKV) emerged in the Caribbean island of Saint-Martin in December 2013. Weimplemented a hospital-based surveillance system to detect and describe CHIKV cases including severe forms of theinfection and deaths in the islands of Martinique and Guadeloupe. A case was defined as a patient with a CHIKV laboratoryconfirmation cared for in a public hospital for chikungunya for at least 24 hours, and a severe CHIKV case was defined as aCHIKV case presenting one or more organ failures. Sociodemographic, clinical, and laboratory data were collected andcases classified into severe or nonsevere based on medical records. From December 2013 to January 2015, a total of1,836 hospitalized cases were identified. Rate of hospital admissions for CHIKV infection was 60 per 10,000 suspectedclinical CHIKV cases and severity accounted for 12 per 10,000. A total of 74 deaths related to CHIKV infection occurred.Infants and elderly people were more frequently hospitalized compared with others and severity was more frequentlyreported in elderly subjects and subjects with underlying health condition. Fifteen neonatal infections consecutive tomother-to-child transmission were diagnosed, seven of which were severe. The most vulnerable groups of the population,such as the elderly, infants, individuals with comorbidities, and pregnant women, should remain the main targets of publichealth priorities.
