Increased parvovirus B19 seropositivity in healthy blood donors in India.

ABSTRACT: A core component of every blood program is the supply of safe blood and blood products. The elevated risk of transmission through these products is due to parvovirus B19 (B19V) resistance to the virus inactivation procedures. Our study aimed to screen asymptomatic blood donors for B19V at a tertiary care hospital in Chennai, Tamil Nadu, between September 2020 and June 2021.

In the study population, 23.5% (n = 25) of donors tested IgM positive, 38.6% (n = 41) tested IgG positive, and 7.5% (n = 8) tested pos
