Cytomegalovirus in Pregnancy and its Effects


Cytomegalovirus (CMV) is a virus that commonly affects many people and tends to remain in their bodies permanently. Majority of people don’t realise that they are affected with the virus, because there are hardly any symptoms. If you have CMV in pregnancy, then there is a risk of passing this virus to your baby.

If you are a healthy person, then CMV shows no harmful effects. Adults and children usually recover easily after experiencing minor symptoms. However, if your immunity is compromised and/or had a recent transplant of bone marrow or organ, then the presence of CMV can cause serious complications, including death. The infection spreads to others, when they come into contact with body fluids of the affected person. It may not be possible to cure this condition completely, but symptoms can be treated using medications.
