CHIKV infection is highly symptomatic and is associated with high-titred viremia. The viremic levels in asymptomatic CHIKV-infected individuals were in the range known to be capable of transmitting the disease to experimental animals. Asymptomatic CHIKV viremia individuals could be potential disseminators of transfusion-associated chikungunya.

The interventions for blood safety measures applied in this study had mitigated the potential transfusion-associated CHIKF during the 2009 epidemic.
