Sir/Madam,

The problem of transfusion-transmitted dengue is very interesting. There is a recent case report that can confirm the evidence of transfusion-transmitted dengue in the most real-time situation.[1] In fact, atypical mode of transmission of dengue including transfusion-related transmission has been mentioned for many years.[2] The present concern is on the safety of the present blood product. Screening for the donor should be strictly done. Of interest, in a recent publication by Stramer et al. is the high rate of dengue viremia that could be observed in donated blood.[3] A similar observation is also reported by Linnen et al.[4] They found that “dengue viremia rates among asymptomatic blood donors from 0.30% in Honduras to 0.04% in Brazil.”[4] Screening for dengue in donated blood is the issue that is widely discussed for its cost-effectiveness.[5] In tropical Southeast Asia where dengue is highly endemic, routine screening is still not in use. Indeed, the incubation period of dengue is rather short and the donor who has dengue infection should exhibit some symptoms, such as fever, that should be detectable during blood donation. Sometimes, the practitioners might overlook the complete screening of vital signs of the blood donor before donation. Making sure that the donor is actually asymptomatic is the basic critical step to guarantee safety.
