Transmission of hepatitis B virus - Explain fully

Hepatitis B Hepatitis B virus Transmission of hepatitis B Route of transmission of hepatitis B virus Main mode of transmission through the following -related aspects communication :
  
Mother to child transmission: It is China's of hepatitis B virus infection most important cause , acute hepatitis B and carrying HBsAg mothers are likely to be hepatitis B transmitted to newborns. the during delivery Transmitted to newborn , in the womb transmission to the newborn ( intrauterine transmission ) , postpartum infection, neonatal .

Blood:Including input with hepatitis B virus in blood and blood products , contaminated injections , surgery , tooth extraction , tattooing , acupuncture, pierced ears , endoscopy and medical staff unexpected stab and other .

Iatrogenic transmission:  Mainly due to use is not strictly sterilized the non- disposable syringes , endoscopes cause . Sexual transmission.

Sexual transmission. HBsAg -positive semen infectious , in the family , HBsAg positive spouses than other family members more susceptible to HBV .

Other forms of communication .About 40 % of the chronically infected in saliva with the virus , so saliva can also cause transmission. Mainly refers to of body fluids the exchange of life exposure , such as sharing razors , toothbrushes and other hygiene products, when the skin and oral mucosa (including gum) damaged when the may be by the break infection. Therefore, the sharing of razor and toothbrush among family members spread were more common .

From the above Hepatitis B virus transmission can be seen , in general, work contact , the occurrence of hepatitis B transmission probability is very low. Daily life in general contact such as sharing office supplies, exchange money , public meals, and generally does not result in transmission.

What is hepatitis B virus carriers ?

Hepatitis B virus carriers , and more that asymptomatic hepatitis B virus carriers (ASC), refers to the blood tests alone hepatitis B surface antigen positive for , but also said that hepatitis B antigen and antibody detection of positive various modes of persons ( the surface of antibody single -positive other than ), But no of hepatitis signs and symptoms , the liver function tests normal, after six months observed no changes were . Generally believed that hepatitis B virus carriers can as usual work and study .

According to statistics, about one tenth of the people may carry hepatitis B virus. the formation Mainly due to mother to child transmission and immune function with weak young people , and adult exposure to hepatitis B virus.

What is hepatitis B virus carriers , asymptomatic HBsAg carriers were divided into 3 categories: 1. suffered from hepatitis, and I had no idea . because of its Clinical symptoms and liver damage mild and soon recover only the performance of as the disease after HBsAg carrier state . 2. health carriers , after repeatedly tests liver function are normal , without any symptoms and signs , even for liver biopsy has no pathological damage , liver tissue structural integrity. 3. The liver biopsy diagnosis of chronic persistent hepatitis, chronic active hepatitis.

The first asymptomatic HBsAg carriers should be medical tracking, every 3 months, review once liver function , in order to keep abreast of whether the liver damage , if liver damage it should be treated.

The second category asymptomatic HBsAg carriers of can be according to work, study and labor , most people with good prognosis , over time , with the body's own immune status of the improvement can be natural negative .

The third category of asymptomatic HBsAg carriers of confirmed the liver pathological damage after , should be now patients treated , timely treatment.

Asymptomatic HBsAg carriers was not really a "healthy person " , the human body, the presence of virus , but also for duplication or infecting others the possibility of , it should not be engaged in the food service industry and conservation. HBsAg carriers should pay attention to personal hygiene and public health, to develop good health habits , the implementation of Dining System ; do not with other mix toiletries . Women should also pay attention to menstrual hygiene to prevent blood contamination daily necessities.

What is hepatitis B virus carriers , the current asymptomatic HBsAg carriers medical principles main has three : 1. to protect the liver : absolute alcohol , avoid fatigue and maintain ease of mind , rational nutrition , regular review of hepatitis B virus markers and liver Function , if necessary, taking ascorbic acid, Paul Gan -dimensional Yang powder to enhance the body resistance and strengthen the liver, nutrition, avoid blind medication. 2. anti-HBV treatment: of specialists in under the guidance medicine , such as the use of interferon , lamivudine, anti-hepatitis B immune ribonucleic acid and medicine and so on. 3. Family Personal Health Care: other family members can injection of hepatitis B vaccine prevent infection . Asymptomatic HBsAg carriers living appliances, clothing, available 0.2% of the 84 disinfectant immersion (20 minutes) , dishes can be with cooked 30 minutes methods disinfection or separate use of .

In short, the hepatitis B virus carriers generally outcome good , there a small part of may be the natural negative ; most for the sustained and stable life hepatitis B virus carrier state ( of which about half of occur liver slight pathological changes in , this change is relatively stable a Types of hepatitis B virus persistent infection , low response state, in need of treatment . ); but about 3% of can occur hepatitis , and liver cancer the possibility of than non- carriers is much greater .
