The hepatitis B virus is actively replicating in the human body, and the blood, saliva, semen, breast milk, cervical secretion and urine of these patients may be infectious. If there is also a person with increased transaminase, first of all, attention should be paid to isolation, and the dishes and chopsticks of the patients in the family can be separately separated from those of their family members, and disinfected on a regular basis, and the patients should be referred to specialized hospitals to adopt antiviral measures to improve the immunity of the body and to reduce liver enzymes and protect liver. The patient should go to a specialized hospital to adopt antiviral, improve body immunity and symptomatic measures to reduce enzymes and protect liver. For close contact with family members should also check liver function and hepatitis B virus infection indicators, if “two half” five negative, should be immediately injected with hepatitis B vaccine to prevent. The situation of patients with minor triple positive is not simpler than that of major triple positive; it should be analyzed according to the specific situation. HBV-DAN and liver function should be examined for hepatitis B minor triple positive, if HBV-DAN is positive and liver function is abnormal, it means that the virus is replicating and highly infectious, and comprehensive treatment mainly based on antiviral should be adopted. If HBV-DAN test is negative, liver function and ultrasound are normal for a long time, it means that the virus is not replicating and is not contagious, so there is no need for quarantine and treatment, and you can work, study, live and get married and have children as normal people do. How is hepatitis B transmitted? (1) Transmission through blood: such as importing whole blood, plasma, serum or other blood products, transmission through blood-borne injection. (2) Fetal transmission: such as the vertical transmission of hepatitis B from pregnant women to newborns through the birth canal; the infection of fetus by pregnant women with hepatitis in late pregnancy. (3) medical transmission: such as medical equipment contaminated by hepatitis B virus after sterilization is not complete or improper handling, can cause transmission; with a syringe for several people to prevent injection is also one of the ways of medical transmission; hemodialysis patients are often the object of hepatitis B transmission. (4) Sexual contact transmission: in recent years, foreign reports on sexual promiscuity, homosexuality and heterosexuality observation is sure: sexual transmission of hepatitis B is an important way of infection of sexual partners, and this kind of transmission also includes transmission between husband and wife in the family. (5) Insect bite transmission: mosquitoes in the tropics and subtropics, as well as a variety of blood-sucking insects, may play a role in the transmission of hepatitis B. The spread of hepatitis B is also a major cause of the spread of the disease. (6) Life close contact transmission: with hepatitis B patients or virus carriers in close contact for a long time, saliva, urine, blood, bile and breast milk, can be contaminated utensils, objects, through the broken skin, mucous membranes and spread hepatitis B. Therefore, hepatitis B is not transmitted through the air, digestive tract or diet. Working and talking in the same room will not be infectious, eating together is generally not infectious (unless there are mouth or digestive tract ulcers), and hepatitis B is generally not transmitted to other people through shaking hands (unless both hands are cracked and bleeding).
