Summary
Several viral infections can harm fetuses. Cytomegalovirus and herpesvirus can cause congenital anomalies, while others like influenza have less clear risks.
Area of Science:
- Virology
- Maternal-Fetal Medicine
- Congenital Anomalies
Background:
- Rubella is a known cause of fetal anomalies.
- Other viral infections also pose risks to fetal development.
- Understanding these risks is crucial for prenatal care.
Purpose of the Study:
- To review viral infections that can cause fetal anomalies and disease.
- To highlight specific viruses with known or potential teratogenic effects.
- To inform healthcare providers about prenatal viral infection risks.
Main Methods:
- Literature review of viral infections and their impact on fetal health.
- Identification of viruses with established or suspected teratogenic potential.
- Categorization of viruses based on the clarity of their risk to the fetus.
Main Results:
- Cytomegalovirus is identified as a significant viral threat to fetal development.
- Herpesvirus and hepatitis B virus are noted for mother-to-offspring transmission.
- Varicella, mumps, and influenza viruses present less defined risks for fetal harm.
Conclusions:
- Multiple viral infections, beyond rubella, can lead to adverse fetal outcomes.
- Cytomegalovirus poses a notable risk, requiring attention in prenatal settings.
- Further research is needed to clarify the teratogenic potential of certain viral agents.
