Chronic hepatitis B, also known as chronic hepatitis B (CHB), refers to individuals who test positive for the presence of hepatitis B virus (HBV) and have a clinical presentation consistent with chronic hepatitis over a period exceeding six months or whose onset date is not definitively identified but who exhibit signs of chronic liver disease.
Clinical manifestations include nausea, aversion to food, abdominal distension, fatigue, and pain in the liver area. In severe cases, there is also a chronic liver disease appearance, such as spider angiomas, palmar erythema, and splenomegaly, with abnormal or persistent liver function tests.
Based on clinical manifestations, it can be divided into mild, moderate, and severe.
The incubation period for hepatitis B is 6 weeks to 6 months, typically three months.
Chronic hepatitis B may cause various complications in different systems of the human body, including: hepatic diabetes mellitus, fatty liver, hyperbilirubinemia after hepatitis, and cirrhosis.
In the treatment of chronic hepatitis B, it is generally advisable to adhere to the principle of "three parts medicine and seven parts regulation". During treatment, one should maintain a positive mental state, keep life in order, eat a balanced diet, engage in appropriate exercise, and avoid over-nutrition.
Hepatitis B can be transmitted.
Hepatitis B is caused by the hepatitis B virus, and the virus can be found in the body fluids of patients such as sweat, saliva, blood, menstrual blood, breast milk, and tears. When exposed to the above-mentioned bodily fluids and secretions from infected individuals, the hepatitis B virus enters the blood or body fluids of an individual and causes infection.
Hepatitis B virus (HBV) primarily spreads through the following routes: 1. Blood-borne transmission, such as plasma, serum, whole blood or other blood products, and transfusion-related infection;
Insects such as mosquitoes and blood-sucking insects bite and transmit.
Sexual transmission is another main route for hepatitis B transmission, including between spouses.
Transmission from the mother to the fetus via the umbilical cord during vertical transmission of hepatitis B.
Medical-related transmission, which includes many cases of infection due to microdose injections or vaccinations in hepatitis B transmission.
Hepatitis B virus is transmitted through injection, blood sampling, tooth extraction, surgery, vaccination, puncture, tattooing or various medical devices, even the hands of healthcare workers.
Contact transmission can also lead to infection, especially when close contact occurs among family members, such as using shared bowls, utensils, towels, and toothbrushes.
Is Hepatitis B contagious when eating? The three main transmission routes of hepatitis B virus are: blood-to-blood contact, vertical transmission from mother to child, and sexual intercourse.
Hepatitis B virus does not spread through the digestive tract or respiratory tract, so daily contact such as handshakes, hugs, work, dining, etc., is generally not contagious.
However, it is important to note that do not share towels, toothbrushes, dishes, cups and other household items with others. If either party has a sore mouth or skin injury, there is a possibility of transmission.
Is Hepatitis B contagious to my husband? Hepatitis B is infectious and primarily transmitted through blood contact, sexual intercourse, and vertical transmission.
In a marital relationship, the likelihood of transmitting hepatitis B virus through sexual intercourse and sharing utensils such as bowls, cups, towels is relatively high.
Therefore, if one spouse becomes ill, both should immediately undergo hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (anti-HBc) testing for the prevention of infection.
Hepatitis B can be transmitted to the next generation. If both parents are carriers of the virus, and immunization is not carried out in a timely manner, then the child will definitely contract the Hepatitis B virus.
If the father is a carrier of Hepatitis B virus, about 30% to 40% of children born from him will be infected without precautions, which is known as vertical transmission.
If the mother is a carrier of hepatitis B virus, especially with "three major viruses", if you do not pay attention to immunization prevention, almost everyone will be infected.
To protect infants from infection, pregnant women are required to receive high-dose immunoglobulin injections every month during pregnancy months 7, 8, and 9. Within 4-8 hours after the birth of the baby, it is necessary to administer hepatitis B vaccine and high-dose immunoglobulin. A second dose of high-dose immunoglobulin and hepatitis B vaccine should be administered at one month after birth, and a third dose of hepatitis B vaccine at six months after birth. This approach can ensure that 90% of infants are protected from hepatitis B virus infection.
