By on January 8, 2018 in Pregnancy with 0 Comments

Cytomegalovirus, also known as CMV, belongs to the herpes virus family, which is inclusive of chicken pox, cold sores and infectious mononucleosis. Majority of American adults are affected by this common virus. The most amazing part of this virus is that it comes and goes without notice, without many symptoms. However, reports have come which have evidence that this virus has the ability of creating complications for an unborn baby.

How common is the cytomegalovirus (CMV)?

You might not know but more than half of pregnant women have CMV virus dormant in their bodies. This might be there from some previous infection, which happened during childhood. If the dormant virus is already there, there are no risks of catching that again during pregnancy. Many women have CMV while they are expecting. It has been seen that about 1-4%of pregnant women get cytomegalovirus for the first time and in that 1 in 3 women transmit the virus to the baby even before delivery.

Transmission of the virus

There are chances of CMV transmission when a woman is in prolonged contact with some kind of infected body fluid. This might include urine, blood, saliva, mucous, semen and even feces. Many women work with little kids and their chances of infections are higher. This is because the cytomegalovirus is very commonly found in the urine and saliva of young kids, particularly in the age group of 1-3years. The infection can be spread among many toddlers at playgrounds and at various day care centers.

Cytomegalovirus

Moreover, the CMV virus can be transmitted from the blood of the mother to the baby at any time during the whole pregnancy period. The infection transmits through the placenta. This is more common when the infection of the mother is for the first time. It might also take place when the infection is with a different strain of the CMV. There are also chances of the virus getting ‘reactivated’ as the immune system gets compromised due to some serious illness or health condition.

Who are at high risk of CMV?

Women who did not have prior infection with CMV before pregnancy are at high risk of getting the infection during pregnancy. It is difficult to diagnose the problem at the first go as there are so prominent symptoms. Even if there are symptoms, they match with signs and symptoms of other kinds of viral infections. Serious problems from cytomegalovirus infections take place mainly in earlier phases of pregnancy. It is in the initial trimester that the chances of infections are high. Hygienic precautions are highly recommended at this time of the pregnancy so that the chances of infections are minimized.
