With the national immunization program for hepatitis B vaccination, the prevalence of hepatitis B in children in China has plummeted, but there are still some sick children who are infected with hepatitis B due to failure of mother-to-child blockade of hepatitis B. In addition, the liver function damage caused by cytomegalovirus infection in infancy should not be ignored as well. Parents should try not to play kissing with their babies mouth-to-mouth to avoid passing the cytomegalovirus you carry to your baby. Cytomegalovirus infection, the main cause of hepatitis in young children Pregnant mothers infected with cytomegalovirus during pregnancy have little effect on themselves, but the impact on the fetus is significant, possibly causing intrauterine infection, which can have different degrees of damage to the fetus’ nervous system, hearing, intelligence, vision, and liver development. In addition, cytomegalovirus infection is also the most important cause of liver disease in infants (especially newborns), which accounts for 40-60% of liver disease in infancy and childhood. Director Xu Yixing said that cytomegalovirus is not a big threat to adults because of the perfect immune system of adults, but once infected with the virus will carry the virus for life, about 95% of adults have cytomegalovirus, and it is easy to pass the virus to babies, and about 80% of infants and children within three years of age have been infected with cytomegalovirus. Because of their imperfect immune system, infants and children are prone to hepatitis. Cytomegalic infected people have the highest amount of virus in their urine and saliva, so doctors advise mothers: “Try not to play kissing with your child, because the virus in saliva is easily transmitted to your baby, and do not feed mouth-to-mouth. Some elderly people worry that their babies can’t bite the food, they like to bite two bites themselves before stuffing the baby to eat, this habit must be changed. In addition, wash your hands before feeding your baby, and keep your child’s eating utensils separate from adults, pay attention to disinfection and use them separately.” Hepatitis B virus carriers, to choose the right time to get pregnant More than 100 million people in China carry the hepatitis B virus, hepatitis B virus carriers, if not careful, the birth of a child will pass the virus to the baby through mother-to-child transmission. Therefore, Xu Yi reminds that these women must choose the best time to conceive. Get pregnant when the virus is controlled at a low titer through treatment, and inject hepatitis B immunoglobulin within one month of the expected delivery date. Hepatitis B immunoglobulin injections within 12 hours of birth, along with the first dose of hepatitis B vaccine, can have a 95 percent chance of blocking mother-to-child transmission of the hepatitis B virus. Subsequently, infants are given the hepatitis B vaccine in the first and sixth months of life to complete the immunization schedule. This way, the baby’s body can produce effective antibodies to avoid infection with the hepatitis B virus. It is also reminded that the transmission of hepatitis B virus is mainly through blood. If the mother carries the virus, she may also be infected with the virus due to bleeding from a ruptured nipple and a broken baby’s mouth while breastfeeding.
