I want to ask whether hepatitis B carriers can study abroad.

Liver function and two-and-a-half are the key items of physical examination for immigrants studying abroad, and hepatitis B virus carriers can generally pass the physical examination if they are not contagious. However, the final decision on the results of your physical examination is in the hands of the local doctor in the country where you are going.

For example, in Australia:

Anyone who goes to any clinic for blood test and tests five indicators of hepatitis B, even if you are only positive for S antigen (surface antigen), the doctor must inform the health department of the state (or territory) where you are located, and then you will receive a letter from the government health department one or two months later, reminding you that you are already a hepatitis B carrier, and it is best to go to the hospital for examination every three months. But this does not mean that they care about hepatitis B, but that the federal government cares about the subjects under the Southern Cross.

During the medical examination of skilled immigrants, they also don't care about hepatitis B. Except for pregnant women who are not exempted from hepatitis B examination, most other medical examiners will not check it, but if the medical examiner thinks it is necessary for you to do it, you must obey it. And even if you are unfortunate enough to meet such an unlucky doctor and help you find out hepatitis B, it will not affect your immigration application. At most, you will be required to report your illness to the government health department regularly after you arrive in Australia.
