Core tip: Severe infectious complications, especially due to viral pathogens remain the leading cause of the post-transplantation morbidity and mortality. In this context, excluding the viral-contaminated umbilical cord blood (UCB) units might be an effective policy to reduce the infection rate after UCB transplantation (UCBT). Complete prevention of the transmission of donor-derived viral pathogens via UCB is not possible. However, having the knowledge of the transmission route and the prevalence of viruses will improve the transplantation safety by controlled patient management. This minireview summarizes the general aspects concerning the prevalence, characteristics and risk factors of viral infections with a focus on the impact on UCBT safety.
