Prevalence of Chikungunya, Dengue and Zika viruses in blood donors: a systematic literature review and meta-analysis

DISCUSSION: Our study shows a high proportion of donors who are viraemic and asymptomatic, especially during outbreaks, with prevalences surpassing 5% for DENV, 1% for CHIKV, and 2% for ZIKV. These data confirm a clear threat to blood transfusion safety. The elevated seroprevalence for these three arboviruses is also indicative of their wide circulation in populations, correlating with an increased risk of infected but asymptomatic donors. Health centres and institutions must address this threat, especially in tropical regions where the biggest outbreaks occur.PMID:34694219 | DOI:10.2450/2021.0106-21
