Abstract excerpt

During September 2025-January 2026, 111 travellers (61 female/50 male; median age: 53 years) who acquired chikungunya virus (CHIKV) in Cuba were reported to GeoSentinel. Upon return, 64.2% (70/109) were potentially viraemic. Only 8.2% (9/98) had received pre-travel consultations. The CHIKV was of East-Central-South Africa genotype, closely related to Brazilian strains. International travellers can serve as...
