How do fetal babies to stay away from hepatitis b

Blocking HBV transmission

Hepatitis b is common in China, about 8%~15% of people suffering from this disease. Most of them are asymptomatic carriers of hepatitis b virus, hepatitis b surface antigen (HBSAg) positive, including one-third has certain infectious.

In China, about 30%~50% of patients with hepatitis b is transmitted by the maternal and child illnesses, HBsAg-positive mother of the child more than 80% infected with hepatitis b virus.

For hepatitis b, could not see how not to blame, because hepatitis b except for can be transmitted to someone, a few can also develop in patients with liver cirrhosis and liver cancer, liver function in pregnancy may also deteriorate, failure. So for HBV should pay attention to.

Detailed, specific understanding of hepatitis b disease, light surface antigens were not enough, should do two half (five), is dasanyang or xiaosanyang. The former is five diyi、San、Wu in positive, which is diyi、SI、Wu-positive. Third positive note with strong infectious. Fourth positive note infectious has been greatly reduced. Fifth positive note may have a certain infectious. So pregnant women should check hepatitis b two semi. Conditions and HBV DNA.

Hepatitis b transmission in addition to fetal infection, sexual transmission, blood-borne. Because blood (including menstrual blood), semen, sweat, saliva, breast milk can contain hepatitis b virus. It was investigating a lot of couples, found party suffering from hepatitis b, chances of contracting hepatitis b the other party is not high. Experts believe that not all of fetal vertical transmission from mother because the blood in utero infection, also include the spreading of intrapartum and postpartum.

Hepatitis b cure after pregnancy, such as well, of course, but hepatitis b have still no specific treatment methods, lamivudine have a certain effect on dasanyang. Newspapers, telephone poles on the \"King of negative conversion\" of propaganda is to deceive peo

ple. Surface antigen-positive half can heal after two years turned cloudy. Mother the second, fourth, two of antibody-positive, 90% will not be transmitted to the fetus.

Two semi-positive pregnant women if pregnancy tests only the first item, do not need medication during pregnancy. May, within a period of 24 hours gave an injection of hepatitis b vaccine to children, a period of 1 month, 6 months and then a shot. Also in postpartum hepatitis b immunoglobulin a fight right away.

Two positive semi-diyi、San、Wu (dasanyang) can be in the diqi、BA、jiuge pregnancy month by playing a hepatitis b immune globulin, postpartum and then injection of hepatitis b vaccine and hepatitis b as described above to children, works well to prevent fetal infection hepatitis b , minus the two-thirds.

Diyi、SI、Wu-positive (xiaosanyang) who deal with dasanyang.

Big, xiaosanyang mother\'s breastfeeding problems are controversial, e Antigen positive not breastfeeding, e antibody-positive babies. Check the value of HBV-DNA is also a guided. If the DNA-positive, not breastfeeding.

Hepatitis b patients with disinfection of utensils, supplies, and other problems more difficult, because HBV is not afraid of boiling water to Cook, General sterilizing drugs on it useless. Now know Peracetic acid can kill it, 0.2% of Peracetic acid soak for 10 minutes. \"84\" disinfectant (200~500 times dilution) 5 minutes can be.

Blocking hepatitis b parent-friendly communication

We all know that hepatitis b through \"transmission\", but is little known, hepatitis b can also be \"parent-friendly communication\". This is because the father has hepatitis b, and their semen can be checked out in HBV DNA (genetic material), in the presence of the virus in sperm cell head slurry, fertilization when the eggs, while the mother is no hepatitis b , is still available cells continue to replicate in future generations, to tire baby. Due to the birth the baby\'s immune system and the feature

is not yet mature, immune tolerance to HBV infection often occur, not only its own long-term with HIV after birth, and will continue to infect others. If fetal baby being infected, get vaccinated after birth is also useless. Therefore, blocking hepatitis b \"parent-friendly communication\" prevention in the \"not\" is very important. So, how to prevent hepatitis b \"parent-friendly communication?\" experts believe that the couple before marriage to be checked for hepatitis b, if a man has been infected with hepatitis b virus is found, the woman is not infected, the woman must be timely immunization with hepatitis b vaccine , make himself hepatitis b surface antibody (anti-HBs). Because there is enough in the maternal hepatitis b surface antibody, and father of hepatitis b virus can, prevent hepatitis b \"parent-friendly communication\". According to the information, do so after mother immunization rate of 95%, while infant infection rate is only 2.6%. Two issues are important to note here: mother following immunization with hepatitis b vaccine in the future, you should check whether the body produces antibodies, if not, should also strengthen immune until anti-hbsab, success to be immune.
