The Potential Impact of Chikungunya Virus Outbreaks on Blood Transfusion
2019
Abstract Chikungunya virus (CHIKV) is responsible for large periodic epidemics in both endemic and non-endemic areas where competent mosquitoes are present. Transmission of CHIKV by transfusion during explosive outbreaks has never been documented and the true impact of CHIKV infection on blood transfusion during an outbreak is unknown. Considerations include not only transfusions in the active outbreak areas but also returning travelers to non-endemic areas. Because there are no documented cases of transfusion-transmitted CHIKV, there are no standard guidelines regarding transfusion policies during a chikungunya fever (CHIKF) outbreak. We review current information from studies during outbreaks with the goal of estimating the potential effect of different blood safety interventions (e.g., querying donors for possible CHIKV exposure, CHIKF-related symptoms, screening for CHIKV RNA).
