Is viral hepatitis contagious

summary

As a doctor, I have met many patients. One patient with viral hepatitis impressed me deeply. He likes singing. Although he is suffering from disease, he is optimistic and actively cooperates with the doctor's treatment. Now let me talk about whether viral hepatitis is contagious.

Is viral hepatitis contagious

First, hepatitis A virus is mainly excreted from the intestines and transmitted by mouth through daily life; hepatitis B virus can be excreted to the body through various body fluids, such as blood, semen, vaginal secretions, saliva, milk, menstruation, tears, urine, sweat, etc. in fact, HBsAg has been found in all secretions of patients. Therefore, there are three main ways of transmission of hepatitis B: mother to child, perinatal transmission: mainly due to maternal blood or sheep blood during delivery and close contact after delivery. Iatrogenic transmission: through blood transfusion, plasma, blood products or the use of contaminated syringe needles, acupuncture needles, blood collection equipment. Close contact transmission: transmission through sexual contact or through close contact caused by damaged skin and mucous membrane.

Second: hepatitis C virus is mainly caused by blood transfusion, which accounts for more than 70% of post transfusion hepatitis. The route of transmission of hepatitis D is basically the same as that of hepatitis B. intravenous injection of prohibited drugs, male homosexuals and patients who often use blood products or renal dialysis are the high-risk groups of the disease.

Third, hepatitis E is mainly transmitted through the fecal oral route through the polluted water source. Hepatitis B virus has not been successfully isolated, and its pathogen has not been identified and recognized. At present, there is neither a definite and recognized object nor a specific diagnostic method for hepatitis B. exclusion is still the main method, and the route of transmission is not very clear. The route of transmission of hepatitis G is basically the same as that of hepatitis B and hepatitis C. Therefore, hepatitis G virus can be co infected with hepatitis C or hepatitis B virus.

matters needing attention

Different ways of transmission of viral hepatitis are different, we should pay attention to, if there are patients with viral hepatitis around, do not wait to be infected before you know it. Of course, do not discriminate against patients with viral hepatitis, as long as after reasonable treatment, the disease can be effectively controlled.
