Once adults suffer from hepatitis B, the virus will continue to replicate and destroy the human immune system, not to mention pregnant women and even infants. And a considerable number of them may eventually deteriorate into cirrhosis and liver cancer. Hepatitis B is so harmful, what are the transmission routes we can cut off as far as possible? So how should pregnant women with hepatitis B big three positive block mother to child transmission?
The transmission route of hepatitis B
In addition to fetal transmission, hepatitis B is also transmitted through sexual intercourse and blood, because blood (including menstrual blood), semen, saliva, milk and sweat can carry hepatitis B virus. However, according to the survey, when one party suffers from hepatitis B, the probability of the other party suffering from hepatitis B is not high. Experts believe that vertical transmission from the mother to the fetus is not solely due to blood transmission in the uterus, but also includes transmission during and after childbirth.
How to block mother to child transmission
1. Hepatitis B positive pregnant women should be injected with a high titer hepatitis B immunoglobulin in the 7th, 8th and 9th month of pregnancy respectively to prevent intrauterine infection of hepatitis B virus and let the newborn born healthy. Then, active and passive combined immunization should be carried out immediately after the newborn is born. Active immunization means that the newborn is vaccinated with hepatitis B vaccine within 24 hours, one month and six months after birth, and passive immunization means that hepatitis B immunoglobulin is injected immediately after birth. If passive immunization is added after active immunization, the blocking rate can reach 3-5 times that of traditional methods.
2. Breastfeeding is a problem of hepatitis B big three positive, because it will cause mother to child transmission, so if the HBV-DNA is positive, breast feeding is not recommended, and artificial feeding is better. Hepatitis B big three positive pregnant women should pay attention to diet. Professor Cai, a hepatobiliary expert, pointed out that pregnant women with hepatitis B big three positive should drink more water and eat more vegetables and fruits, and not be partial to food. The diet should be as wide and diverse as possible, and eat more high protein and high-quality protein foods and more vegetables and fruits. Do not drink alcohol or coffee, quit smoking, avoid contact with toxic substances and radiation sources, prevent colds, and avoid spicy foods.
It is really worrisome if pregnant women have hepatitis B big three positive, because hepatitis B big three positive will also affect the fetus. Pregnant women with this disease must undergo regular medical examinations at the hospital to prevent transmission to other family members. And people around pregnant women should also get vaccinated in a timely manner and take preventive measures.
