Small three positive virus carrier

The small triple positive virus is a type of hepatitis B virus. The small triple positive virus carrier refers to people who carry the hepatitis B virus. This group of people usually have low resistance or no antibodies against hepatitis B virus. If not treated in time, it is likely to turn into liver cancer or cirrhosis, making later treatment more difficult. Below, we will introduce you to the relevant knowledge about hepatitis B virus carriers in detail!

1. What is a hepatitis B virus carrier? Is it related to “big triple positive and small triple positive”?

Hepatitis B virus carriers refer to those whose liver function remains normal and who have no clinical symptoms. They are often found to be HBsAg positive during physical examinations or blood donations, and have no abnormalities found in liver B-ultrasound. These people are not hepatitis B patients. Anti-HBc, HBsAg, HBeAg or anti-HBe and HBV DNA can be detected in the serum of HBsAg carriers. Therefore, no matter whether it is "big triple positive" or "small triple positive", as long as the liver function remains normal and no abnormalities are found in the B-ultrasound, the person is a carrier.

2. How does hepatitis B become a carrier?

The reason why HBsAg becomes a carrier is mainly related to the body's low immune function against the hepatitis B virus. The hepatitis B virus itself does not cause liver damage. Its liver damage is mainly caused by the immune damage to liver cells in the process of the body clearing the hepatitis B virus. In most hepatitis B virus carriers, the body's immune system and the virus are in a state of "peaceful coexistence", and the immune system cannot recognize and eliminate the virus, and the liver damage caused by the virus is also very limited. For example, when the virus is transmitted from mother to child, the infant is infected with a large amount of invading hepatitis B virus (HBV). At the same time, because the immune system is not yet fully developed and lacks the ability to clear the immune system, the infant is in a state of "immune tolerance", which manifests as long-term HBsAg carriage. Adolescents or adults with compromised or low immune function may also become HBsAg carriers after being infected with HBV.

3. Will all hepatitis B carriers develop liver cancer and cirrhosis?

Many patients have heard from doctors that if chronic hepatitis B is not treated in time, it can easily develop into liver cancer and cirrhosis. The actual situation is that if chronic hepatitis is not treated actively, the proportion of developing cirrhosis each year is 1%, and 1 in 100 people will develop cirrhosis each year. However, hepatitis B virus carriers and chronic hepatitis B are two different concepts. About 20% of hepatitis B virus carriers will develop chronic hepatitis, while the vast majority of others can maintain a long-term dormant state of the disease. For those who remain in a dormant state of the disease for a long time, the probability of developing cirrhosis each year is only 0.01%.

However, it is still not possible to accurately predict which hepatitis B virus carriers will experience liver tissue inflammation and thus develop into chronic hepatitis. Therefore, regular physical examinations and timely treatment of abnormal liver function are crucial.

4. Can hepatitis B carriers marry and have children normally?

Can. If your spouse receives regular hepatitis B vaccination, you can avoid being infected. Even if they are accidentally infected, since adults have a sound immune system, 95% of people can completely eliminate the virus and recover completely, and only 5% will develop a chronic disease. Some patients are afraid of spreading the virus to the next generation and dare not have children. In fact, if the infected male is infected, the possibility of transmitting the virus to the next generation through germ cells is very small; if the infected female is infected, as long as formal mother-to-child transmission is blocked, the possibility of transmission to the next generation is less than 10%.

5. What issues should hepatitis B carriers pay attention to in their daily lives?

Medical observation should be carried out regularly, and overwork should be avoided in daily life. Work and rest should be combined, a happy mood should be maintained, personal hygiene should be improved, and one should consciously prevent one's own blood, saliva, urine and other body fluid secretions from polluting the surrounding environment; personal utensils, razors, shaving masks, toothbrushes and toiletries should be used and kept properly. HBsAg carriers should also pay attention to protecting their livers, abstaining from alcohol and the use of drugs that damage the liver, and pay attention to the prevention and treatment of other diseases, especially infectious diseases, to avoid further damage to the liver. In terms of medical observation and follow-up, follow-up examinations should be conducted every six months to a year, and medical treatment should be sought at any time if any abnormalities are felt. Follow-up examinations should include physical examination, liver function, serum HBV infection indicators and liver B-ultrasound examination. Serum alpha-fetoprotein should be tested for those over 40 years old so as to detect changes in the disease in time and take appropriate treatment measures.
