Hepatitis B is not included. Your visa will not be denied because you are a Hepatitis B carrier (HBeAg-positive or HBeAb-positive).
The assessment is based on the results of the five Hepatitis B indicators: HBsAg (Australia antigen), HBsAb, HBcAb, HBeAg, and HBeAb.
1. HBsAg positive, with the other four indicators negative. This is considered normal, and a health certificate will be issued.
2. HBsAg positive, but HBeAb-positive (small three-positive), meaning indicators 1, 4, and 5 are positive, and liver function is normal. This is considered normal, and a health certificate will be issued.
3. HBsAg positive, but HBeAg-positive (large three-positive), meaning indicators 1, 3, and 4 are positive, and liver function is normal. This is actually considered healthy, but according to the regulations of China's health and quarantine departments, a health certificate is not issued.
4. HBsAg positive, large three-positive, and abnormal liver function. This likely indicates active hepatitis; it is best to treat the condition domestically first.
None of the above situations (1, 2, or 3) will affect your departure from China, and U.S. immigration does not check health certificates upon entry.
