Seasonal influenza A (H1N1) infection in early pregnancy and second trimester fetal demise

Emerg Infect Dis. 2011 Jan;17(1):107-9. doi: 10.3201/eid1701.091895.

Abstract

A second trimester fetal demise followed influenza-like illness in early pregnancy. Influenza A virus (H1N1) was identified in maternal and fetal tissue, confirming transplacental passage. These findings suggested a causal relationship between early exposure and fetal demise. Management of future influenza outbreaks should include evaluation of products of conception associated with fetal loss.
