1, the first type is normal liver function, normal HBV-DNA, no hepatitis symptoms, also known as hepatitis B carrier. In this case, hepatitis B can get a health certificate, but it can only get a Class B health certificate (there are two kinds of health certificates, one is issued to healthy people before and can engage in any type of occupational food health certificate, and the other is not allowed to engage in the food and beverage industry.
2. The second type is abnormal liver function, and HBV-DNA is positive (indicating that hepatitis B virus is in a high replication stage). In this case, patients with hepatitis B, a big three-yang disease, are highly contagious and need active treatment because they can't get a health certificate. Only when the liver function is normal and HBV DNA is stable can they get a health certificate.
