Hepatitis E virus (HEV) infection is considered a neglected disease of major concern in developed countries. Clinically, HEV occurs as an acute and self‐limited disease, though chronic cases mostly associated to HEV‐3 are now being commonly reported in immunocompromised individuals and solid organ transplant recipients. Transmission of HEV through blood and derivatives have been increasingly described in the last years, highlighting the importance of including this agent on the screening programs. Since 2010 both acute and chronic hepatitis E cases have been frequently reported in Uruguay. However, updated prevalence data among different population groups are lacking and HEV is not currently screened in blood banks. Herein, we report a seroprevalence and molecular survey of HEV in 400 plasma samples from blood donors. Overall, our results showed an HEV seroprevalence rate of 10% (40/400); almost 10‐fold higher than 20 years ago. Total anti‐HEV immunoglobulin antibodies were found to increase with age. Moreover, we reported an RNA detection rate of at least 0.75%, and two strains were sequenced. Phylogenetic analysis grouped them with human and swine HEV‐3 strains from Uruguay. Data presented here should prompt public health policies of HEV screening in blood banks to minimize the risk of transfusion‐transmitted hepatitis E.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
