Hepatitis B virus is a hepatotropic virus, which is mainly infected through blood, body fluids, sexual contact and vertical transmission from mother to child. Hepatitis B does not spread through respiratory tract and digestive tract. At present, it is stipulated that patients with hepatitis B can apply for a health certificate as long as their liver function is normal, and they can also engage in catering-related occupations.
The "Regulations on the Implementation of the Food Safety Law" clearly stipulates that hepatitis B virus carriers will no longer be prohibited from engaging in the catering industry, and announced the cancellation of hepatitis B project testing and thresholds for four professional groups such as chefs and restaurant waiters.
