The topic “Chikungunya virus and risk to transfusion” is very interesting.  It is no doubt that chikungunya virus can be transmitted via blood transfusion.  In the past, chikungunya virus infection was prevalent but confined to the tropical zone. However, the present trend shows the movement of the virus into the Western Hemisphere.  Nevertheless, the important concern is whether there is a risk of blood transfusion-associated chikungunya fever and the places where it is necessary to implement blood screening for chikungunya virus. Based on the recent report from Thailand, an endemic region for chikungunya virus, it is concluded that donor screening can be useful during an epidemic.  However, this report cannot imply its usefulness in the normal nonepidemic situation. In fact, the patients with chikungunya virus infection usually have acute febrile illness and this can be easily excluded from blood donation. Appassakij et al. reported that the problem of asymptomatic chikungunya could be seen and it should be focused on since the viremia can be determined in the blood of the cases with asymptomatic chikungunya.  Nevertheless, it is not proved whether the detected viremia further causes the infection in the blood of the recipient or not. Also, if the level of viremia in asymptomatic chikungunya infection causes no problem, it should cause no problem to the recipient. It seems that screening is not the answer to the problem. In endemic areas such as Southeast Asia, there is still no routine screening for chikungunya virus in blood banks. The use of pathogen reduction technology, which covers chikungunya virus, can manage the problem cost-effectively.
