What’s the first thing that comes to mind when you think of hepatitis? I think most people’s first thought is that it’s an infectious disease. For a long time, people have been in fear of talking about “liver”, but are all hepatitis infectious? What is the truth? Here we will reveal the truth about hepatitis. First of all, we need to clarify whether all hepatitis is contagious? The answer is no, not all hepatitis is contagious. To understand this issue, first we need to be clear about what is hepatitis? Hepatitis is a general term for various inflammatory diseases of the liver. According to the cause of the disease is divided into the following categories: 1, viral hepatitis: the most common and the most dangerous type of hepatitis, with infectious. Viral hepatitis is a systemic disease caused by a variety of hepatitis viruses, with liver damage as the main cause. The main clinical manifestations are loss of appetite, nausea, upper abdominal discomfort, liver pain, and weakness. Some patients may have jaundice fever and hepatomegaly with liver function impairment. Divided into five types of hepatitis A, B, C, D and E viruses. 2, alcoholic liver disease: With the improvement of people’s lives, the incidence of alcoholic liver disease due to long-term heavy drinking is increasing, and has become the second largest cause of liver disease after viral hepatitis. This cause of liver disease is not contagious. 3, non-alcoholic fatty liver disease: non-alcoholic fatty liver disease is a clinicopathological syndrome characterized by excessive fat deposition in liver cells, except for alcohol and other clear liver-damaging factors. Obesity, diabetes mellitus, hyperlipidemia, hypertension, and changes in diet structure are closely related to its development. It is a common cause of liver function abnormalities in the physical examination population and is not contagious. 4, drug liver disease: due to the use of drugs, directly or indirectly caused damage to the liver caused by liver disease that is drug liver disease. Discontinuation of drugs that cause or may cause this disease is the most important treatment, such liver disease is also not contagious. 5, autoimmune hepatitis: autoimmune hepatitis is a chronic progressive liver inflammatory disease mediated by autoimmune reactions, the cause is not completely clear, not contagious. 6, other factors: such as bacteria, parasites, chemical toxins, etc. can also cause liver inflammation. Among the above-mentioned types of hepatitis, only viral hepatitis is contagious. Of this type of hepatitis, hepatitis B is the most common infectious disease in China. What are the ways of transmission of hepatitis B? 1, mother-to-child transmission: there are three ways of mother-to-child transmission of hepatitis B: intrauterine infection, infection during childbirth and postpartum infection. Intrauterine infection is the fetus in the mother’s body during the growth and development of the maternal hepatitis B virus infection; intrapartum infection refers to the mother in childbirth, the newborn swallowed mother’s blood, amniotic fluid, vaginal secretions containing hepatitis B virus, or during childbirth due to uterine contractions prompted a small amount of maternal blood leakage into the fetal blood circulation caused by infant infection; postpartum infection is mainly through breastfeeding and close contact with life transmission. 2, blood transmission: through blood transfusion, the use of blood products, or the use of medical equipment contaminated by the patient (such as syringes, puncture needles, scalpels, dental drills, endoscopes, etc.) caused by infection. In daily life, the hepatitis B virus carrier’s saliva, urine, bile, milk and other human secretions enter the body through broken skin and mucous membranes and become infectious. In addition, poor hygiene habits such as sharing toothbrushes, teacups, scissors or razors, etc. can also cause transmission through a small amount of blood. 3, sexual contact transmission: in the family, if one of the couple is a hepatitis B patient or hepatitis B virus carrier, the other party is also susceptible to infection. In addition, the rate of hepatitis B positivity is also higher in sexually confused people. So what should we pay attention to in our daily life? 1, Hepatitis B vaccine prevention: Hepatitis B vaccination is the most effective way to prevent HBV infection. As the hepatitis B virus population is generally susceptible, so regular checkups and timely vaccination are needed. 2, in daily life, develop good hygiene habits, do not share toothbrushes, towels, teacups and other items. However, it should be noted that in our daily life, such as sharing utensils, hugging, kissing, shaking hands, coughing, playing games together, traveling, living in the same room, going to work together, or playing in public swimming pools and other similar behaviors do not infect hepatitis B. There is no need to be too alarmed. 3. If you have hepatitis B infection before pregnancy, you need to control the disease and then get pregnant. If hepatitis B is detected during pregnancy, mother-to-child blocking treatment should be performed in time at 6 months to control further replication of the virus, and the child should be vaccinated against hepatitis B in time after birth. Not all hepatitis is contagious, even if you come into contact with viral hepatitis in your daily life, you will not be infected as long as you do not come into contact with the blood and body fluids of the hepatitis patient. Viral hepatitis can be prevented and controlled, so we don’t have to talk about “liver”.
