Hepatitis B transmission channels

The reason: First, hepatitis B transmission (infection) complicated way, the source of infection is widespread. As a source of infection of hepatitis B patients is not only, and anti-Australian carriers are also important source of infection. Infectious diseases control law is the treatment of patients must be isolated, but the O-carriers (number of) can not control but also beyond the control of its activities and daily life, it is difficult to control the main reason for hepatitis B, which also infected people do not consciously On the reasons for the hepatitis B virus. Nevertheless, we can be a route of transmission of hepatitis B, prevention, can also play a positive role.
Hepatitis B transmission: mainly through blood transfusion (blood products), injection, treatment appliances, vertical, sexual contact and live in close contact, such as transmission. Now all of these channels have taken certain measures, such as strict management of blood donors, with sensitive detection methods of the project, requested medical units on the medical equipment for one person, one with a disinfectant; syringe (blood collection and transfusion, puncture - Pin) are used disposable supplies for the implementation of neonatal hepatitis B vaccination, especially for O-positive pregnant women to newborns born to a timely (within six hours after birth) enough (10 micrograms of hepatitis B vaccine) injection in checkups in Australia have identified one of the positive, ask for vaccination; life transmitted to the control of only the patient or anti-Australian carriers to self-care and protection to prevent their own saliva, blood and other secretions contaminated the surrounding environment, infecting others.
(2) "Da Sanyang" and "Xiao Sanyang"
Body of hepatitis B virus infection, the immune system cells first, "kill" and "eliminate" the "enemy." Through a period of "combat", the body produced a series of "victory" signs that the hepatitis B surface antigen (O-HBsAg) and hepatitis B surface antibody (anti-- HBs), e antigen (HBeAg) and e antibody (anti - - HBe), the core antibody (anti-- HBc) and other "two pairs half." How should we view these five signs it » If HBsAg, HBeAg and anti - HBc three positive, that is, they say the "three-" that the virus is active in reproduction and breeding, is highly infectious, the patient is in active condition, Warning patients to the attention of rest and treatment. If HBsAg, anti - HBe and anti - HBc three positive, that is, "Xiao Sanyang," generally refers to the virus replication has been controlled or the patient's condition is basically stable, the trend has improved. Anti-- HBs is in and of the antibody, the positive that the body has immunity, is "victory" signs, after the injection of hepatitis B vaccine is produced in this antibody. Anti-- HBc no protective effect, only that the past infection.
(3) O-carriers can be negative?
In addition to hepatitis B patients, O-carriers of hepatitis B virus infection is the greatest danger of a form, including the surrounding crowd, and their own. The surrounding crowd is not a source of infection has played the role of « Afraid of the crowd around, often escape, the police and far, people embarrassed, I am also worried that not only worried about the transmission of family and friends and their children, but also worried that this development will bring state-of patients, can cure » Can hepatitis B vaccine inoculation » When negative » This is the first to say the Australian carriers do not have vaccination against hepatitis B vaccine, even if the vaccine will not be the body to produce antibodies. Carriers of hepatitis B virus infection from the time to read, perinatal infection and contact with live (and work, study and family) infection. The former is subject to mothers infected with the O-positive impact of O-positive pregnant mothers-to-child transmission rate of about 40-90%, of which three to five percent of the people belong to the womb infection, this part of carriers difficult to cure. Life come in contact with the carriers, through treatment, O-negative is highly likely.
