Sex is an important part of a couple’s life, hepatitis B patients who are indiscriminate in their abstinence, it is not right. However, after all, with the disease in the body, the couple’s sex life should be moderated, and both parties should understand and comply. For the spouse of a hepatitis B patient, protective measures must be in place, and the spouse of a hepatitis B patient must be double immunized with hepatitis B vaccine and hepatitis B immunoglobulin to ensure that nothing is lost. Generally, if one spouse does not have the above-mentioned protective measures in place, he or she must use a protective tool such as a condom before having sex. Because the semen, blood or vaginal secretions of hepatitis B patients may contain hepatitis B virus, which can be transmitted to each other through sexual intercourse, with an infection rate of 10-15%. 1, acute hepatitis (1) acute hepatitis period, when the alanine aminotransferase (ALT) significantly elevated, general weakness, jaundice and other symptoms, should prohibit any sexual activity, including masturbation. To avoid overexertion and aggravation of the disease. At the same time, acute hepatitis or chronic hepatitis active period, liver disease patients are contagious, through sexual contact will make sexual partners have the opportunity to infect hepatitis. (2) When acute hepatitis reaches clinical cure, chronic hepatitis basically reaches the standard of cure, the condition is stable for more than six months can have sex life; acute hepatitis clinical cure after one year of follow-up without abnormalities, chronic hepatitis observation for two years without abnormalities can be competent to work, can have a normal sex life. 2, chronic hepatitis (1) chronic hepatitis, cirrhosis patients due to the impact of the disease, the general sexual desire are relatively indifferent, at this time should not be reluctant, but should follow the nature. When the liver disease is controlled, the body’s sex hormone metabolism is adjusted and restored to normal, sexual function can also be improved accordingly. (2) HBsAg carriers can lead a moderated sex life, consciously control the frequency of sex, but not indulge, otherwise it is easy to cause liver disease outbreaks or aggravation. The frequency of sex is generally 1-2 times a week for young people, once every 1-2 weeks for middle-aged people, and 1-2 times a month in late middle age. However, in the period of poor liver function, especially when the transaminases are unstable or appear jaundice persistently elevated should be stopped. (3) alcoholic and fatty liver disease patients mostly have no obvious symptoms, half have liver discomfort, abdominal distension, loss of appetite, impotence, menstrual disorders, abnormal breast development, etc., a few people with mild abnormal liver function, no need to abstain from sex at all, should be temporarily abstained for a period of time when the liver function is abnormal, to be liver function recovery can resume sex life. Moderate sex life helps to relieve sexual tension and achieve a high degree of relaxation of the whole body and mind, but also helps to consume excess fat to reduce the accumulation of fat in the body, but also can play a role in weight loss and fat loss. The number of hepatitis B viruses in patients with minor triplets is much less than in patients with major triplets, and the reproductive capacity of the virus is very low, the active capacity of the virus is greatly suppressed, and the human body will also produce immune antibodies to fight against the viral body, which can keep the liver function from being damaged for a long time. In addition, the contagiousness of DNA-negative minor triplets is extremely low, except for deep contact such as blood transfusions, which may be contagious, general physical contact usually does not infect healthy people with the hepatitis B virus, and the chances of transmission from minor triplets are minimal. The difference between “major and minor triplets” is that “major triplets” have active viral replication, a large number of viruses and are highly contagious; “minor triplets” have low viral replication and a large number of viruses. The difference is that “major triple-positive” people have active viral replication, a large number of viruses and are highly contagious, while “minor triple-positive” people have low viral replication, a small number of viruses and are less contagious (excluding, of course, patients with mutations in the pre-C region of the virus gene). Therefore, the difference between “major and minor triplets” is only in the number of hepatitis B viruses they carry, not in the number of viruses they have and the number of viruses they do not have. Simply put, both “major and minor triplets” carry the hepatitis B virus and are contagious, but the degree of contagiousness is different. The small triplets are mainly transmitted through blood. The small third-positive DNA is just as contagious as the large third-positive. The “two pairs of half” examination of hepatitis B, surface antigen, core antibody is positive, or even only the core antibody is positive, HBV-DNA test is still positive, which still reflects the HBV is still in the replication state, highly infectious.
