1, cytomegalovirus infection is divided into congenital infection (intrauterine infection) and acquired infection; newborns with positive serum cytomegalovirus IgM and DNA within two to three weeks after birth are generally judged as intrauterine infection. Intrauterine infections can mainly affect the baby’s hearing. Intrauterine infections tend to be problematic, while acquired infections are usually asymptomatic. 2. Cytomegalovirus infections are very common and sometimes it is difficult to distinguish between intrauterine infections or infections at birth. Hearing screening can be done, and the main danger is that it affects hearing. 3, cytomegalovirus infection will always be in the body. Most of our people have this virus in their bodies. 4, breastfeeding is not a contraindication to cytomegalovirus infection, many people in our country are positive for cytomegalovirus DNA in breast milk. As long as the child is full term and has normal immune function, it can be breastfed. 5, Cytomegalovirus treatment drugs can have side effects, so treatment is limited to symptomatic infections, limited to those with active cytomegalovirus replication. The indicator of active replication is a positive CMV-DNA in the blood. If the hearing is normal and the blood is negative for CMV-DNA, no treatment is needed. 6, caused by high transaminases, jaundice has many causes, not necessarily cytomegalic infection. 7, giant cell infection is mainly the primary infection will cause problems, infection reactivation will also have problems, but relatively light. 8, on the issue of continuing to breastfeed the baby, some experts believe that do not feed, but some studies have shown that the mother CMV-IgG positive to breastfeed the baby no problem. The vast majority of us have this virus in our bodies, and babies will be infected sooner or later. It was found that by the age of 2, 60% of babies have been infected and only a very small number will show to have the disease. 9, CMV-DNA in the blood can tell whether the virus has replicated, CMV-DNA and CMV-IgG in the urine are not visible. CMV-Igm positive can last for 6 months and is not a good indicator to see whether the virus is replicating. 10. A negative CMV-DNA does not require treatment. Normal hearing does not mean that the virus is not replicating. But normal hearing, your child has no other manifestations, even if CMV-DNA positive, foreign countries do not consider treatment, such as really unsure, treatment of a course of treatment can also be, but we must weigh the effectiveness of treatment and drug side effects. 11, baby’s cytomegalovirus IgG antibody positive, cytomegalovirus IgM antibody positive indicates that the baby is also infected, but does not mean that the blood CMV-DNA is also positive, nor does it indicate that the virus is replicating, because cytomegalovirus IgM antibody can last up to 6 months positive after some people are infected or after one activity, while the blood CMV-DNA lasts for a short time.
