Can pathogens cause birth defects?

Can pathogens cause birth defects?

Some infectious pathogens increase the risk for pregnancy loss (e.g., Listeria monocytogenes and parvovirus B19), while others increase the risk for birth defects that are evident at birth (e.g., rubella and Zika viruses).

What viruses can cause birth defects?

Toxoplasmosis, cytomegalovirus (CMV), varicella, rubella, and lymphocytic choriomeningitis virus (LCMV) are among the agents that are recognized to have the potential to cause birth defects in a developing fetus.

Can immune system affect pregnancy?

Different parts of your immune system are enhanced while others are suppressed. This creates a balance that can prevent infection in the baby without compromising the health of the mother.

Can Covid cause birth defects?

Any functionally alterations in early embryonic cells by the viral infection may lead to adverse birth defects. With much still unknown about COVID-19 and neurodevelopmental complications, there is an increased risk to develop congenital birth defects, if SARS-CoV-2 infection occurs during early pregnancy.

What birth defects are caused by toxoplasmosis?

Toxoplasmosis can cause problems during pregnancy, including miscarriage, preterm birth or stillbirth. Most babies born with toxoplasmosis have no symptoms. Symptoms can include eye infections, swollen glands, liver or spleen, or jaundice.

What virus can cause teratogenic effects?

TORCH group infections (toxoplasmosis, others, rubella, cytomegalovirus, herpes) are the most serious infectious diseases during pregnancy due to the seriousness of possible embryo-fetal lesions.

Is a pregnant woman’s immune system stronger or weaker?
