If it is common to kill the hepatitis B virus, it may refer to disinfecting daily dishes, household items, etc. You can use 84 disinfectant to soak for more than one hour, or you can apply 75% alcohol to destroy the hepatitis B virus, while the hepatitis B virus is sensitive to heat, you can boil 100 degree water for ten minutes to inactivate it. If the treatment is for hepatitis B virus, oral nucleoside analogues can be taken as prescribed by the doctor, and interferon can also be applied, but after treatment there will still be a part of the virus in the liver cells, which cannot be completely eliminated, so the virus will continue to multiply after the antiviral drugs are stopped, so the hepatitis B virus is basically not easily cured, but can only control the patient’s condition from deteriorating. At present, hepatitis B vaccine is widely used and can effectively prevent hepatitis B virus infection, so you can actively inject hepatitis B vaccine and regularly recheck hepatitis B antibody.
