The study examines the prevalence and risks associated with BK Polyomavirus reactivation in pregnant women, highlighting that previous research has produced mixed findings.
It found that 79.2% of pregnant women were seropositive for BK, with a significantly higher odds of reactivation and detection of the virus in urine compared to non-pregnant women.
Despite evidence of vertical transmission to fetuses, the research indicates no strong links between BK infection and negative health outcomes like miscarriage or childhood cancers.
