Sperm can also carry hepatitis B virus

sperm can carry hepatitis B virus

hepatitis B in China is known as a great nation.According to statistics, China's hepatitis B virus carriers as much as nearly 100 million, that is, there is one for every 10 people.Despite the large number of hepatitis B, but not always derived from contact with the patiENTs infected, the vast majority (80%) from the Family of vertical transmission.Vertical transmission of hepatitis B virus, including mother to child transmission and the parent child transmission.For vertical transmission channels and the corresponding control methods have gained a better study abroad.Recently, some studies in China show that the vertical transmission of hepatitis B virus in infants and the spread of the parent can not be ignored, in fact, the parent child transmission of hepatitis B virus, although the risk of mother to child transmission better than many, but once the infection likely to cause life to carry the same However, the parent child transmission of hepatitis B virus Hepatitis B virus is only one way, not genetic diseases, through effective prevention, can block the vertical transmission among infants and the parent.

spread it?

men suffering from hepatitis B, and its hepatitis B virus can be detected in sperm DNA, the virus stored in the cytoplasm of the sperm head, sperm ENTer the egg, even though his mother free from hepatitis, but the fertilized eggs to form embryos in the process of , hepatitis B virus are constantly proliferation, such as hepatitis B patients or progeny virus, and therefore, this mode of transmission of hepatitis B virus, known as the father of infant transmission.

father and mother-child transmission have differENT, studies have shown that hepatitis B virus infection have been the father of the sperm carrying the hepatitis B virus DNA fragments, which DNA fragments can be present in the cytoplasm of the sperm head, through the fertilization to continue in the daughter cell replication, the occurrence of infection in daughter cells, causing the parent of infant hepatitis B transmission.Moreover, even if no fertilization hepatitis B virus infection, but as long as couples living together during Pregnancy, pregnant by her husband still has not been out of the risk of hepatitis B virus infection.Because of close contact with daily life, sex life during pregnancy are likely to be hepatitis B virus infection in pregnant women, and then also through the father - mother - the way the infection of infants and offspring, which is an indirect parent of a child transmission.

surface antigen, e antigen-positive persons, infants born to infected more than 80% chance; when the father e antibody positive, their offspring's chances of infection is about 20%.Fetal infection with hepatitis B virus, hepatitis B patiENTs or in addition to a virus carrier, it can also affect the normal growth and development of the fetus, can cause low birth weight children, congenital diseases or malformations, miscarriage, stillbirth and so on.Therefore, we should parent child transmission of hepatitis B virus seriously enough.

If the spouse Health, and HBV infection is HbsAg positive, or as the"three positive" and"small second sun", HBV-DNA negative and no clinical symptoms, normal liver function, liver and spleen B super no exception, indicating that HBV does not replicate in the body, infectious extremely weak.

infant due to direct spread of the parENT phase occurs in germ cells, thus blocking the spread of hepatitis B infant and parent is the most effective way to Pre-Pregnancy intervention.

one couple before marriage to check for hepatitis B, hepatitis B with either male or female, should be actively treated.Infectious disease to be cured or stable disease after non-married child the best education.The Pre-Pregnancy mothers who have succeeded in the appearance of antibodies to hepatitis B vaccine at this time is the best pregnancy period, to be effective in protecting pregnant women and Newborns, which can effectively reduce the possibility of hepatitis B virus infection.

Second, to prevENT the spread of the parent is to infant immunization measures in accordance with hepatitis B vaccine to Newborns in a timely manner, the child is born to give the hepatitis B vaccination.There are some useful methods available: during Pregnancy, since pregnancy 20 weeks for check intramuscular injection every 4 weeks from the hepatitis B immunoglobulin 200IU, and pregnant women can be effective in hepatitis B virus in the blood, which also aims to further strengthen the resistance of pregnant women husband of hepatitis B virus infection, hepatitis B virus and reduce the father - mother - infant transmission opportunities.Father and (or) mother is hepatitis B virus carriers in addition provisions of newborns born to hepatitis B vaccine injection, but also within 24 hours after birth and 1 month were injected with high hepatitis B immune globulin, a 100IU, to better the protection of newborns.

Therefore, we remind only the father for the couple based on the cases of hepatitis B virus infection, should strengthen the mission, so the spread of hepatitis B virus have a better understanding so as to better meet the medical use of reasonable methods to prevENT Pregnancy and offspring from the father of hepatitis B virus infection.
