Abstract:
The transfusion-transmission risk associated with the major transfusion-relevant pathogens, such as hepatitis B virus, hepatitis C virus and human immunodeficiency virus, has been gradually reduced and maintained at a low level. There has been a growing awareness of the threat to blood safety from emerging andre-emerging infectious diseases, a number of which are known to be, such as plasmodium, human parvovirusB19, hepatitis E virus, dengue virus, human T-lymphocytic leukemia virus and West Nile virus, or are potentially transfusion transmissible, such as novel coronavirus. Among them, dengue virus was regional epidemic in China, and may outbreak again unpredictably in the future. Its threat to blood safety cannot be underestimated. At present, there are only four pathogen screening items for routine blood screening in China. Duetoan increasing number of emergingand re-emerging pathogens and the absence of screening strategies for new pathogens in blood centers, it would be a great challenge to blood safety in China. In this review, we documented the prevalence of several pathogens emerged in China, and discussed the impact on blood safety and the viability of personalized screening strategies foremerginginfectiouspathogens in blood centers.
