Post-chikungunya rheumatic disorders in travelers after return from the Caribbean

Background Due to increasing concerns about post-chikungunya (pCHIK) rheumatic disorders in Latin America we aimed to evaluate its occurrence in travelers returning to NYC from the Caribbean. Method Patients diagnosed with chikungunya (CHIK) during 2014 at the Bronx-Lebanon Hospital Center (Bronx, NewYork) were identified by reviewing laboratory and electronic medical records. Patients and caregivers of pediatric patients were interviewed by phone ≥9 months after the CHIK diagnosis to survey for chronic symptomatology and current health care needs. Reported chronic musculoskeletal complaints were categorized according to validated criteria. Results A total of 28 patients (54% females, median age [range] of 51.5 [0, 88] years) diagnosed with CHIK at our center were identified. Most (82%) had returned from the Dominican Republic. Nineteen (68%) patients were successfully contacted at a median (range) of 13 (9, 16) months since the acute diagnosis. A third (37%) reported ongoing complaints related to CHIK including joint pain (32%), muscle pain (32%), and joint swelling (26%). A presumptive diagnosis of pCHIK chronic inflammatory arthritis (n = 4) and pCHIK musculoskeletal disorder (n = 3) was established. Conclusions A third of travelers with CHIK acquired in the Caribbean may be at risk for developing persistent symptoms suggestive of pCHIK rheumatic disorder.
