Hypothesis
What are the effects of parvovirus B-19 infection during pregnancy?
Conclusion
Parvovirus B-19 infection during pregnancy can lead to serious complications, including fetal hydrops and anemia, but congenital malformations are not increased.
Supporting Evidence
- 3-19% of pregnant women will serologically convert to IgM positive on exposure to parvovirus B-19.
- The risk of fetal demise is highest in the first trimester, reaching approximately 10% if infection occurs before 20 weeks' gestation.
- Studies found no increase in congenital malformations due to parvovirus B-19.
Takeaway
Parvovirus B-19 can make pregnant women and their babies very sick, but it doesn't usually cause birth defects.
Methodology
The study involved prospective and retrospective analyses of pregnant women and their outcomes related to parvovirus B-19 infection.
Limitations
