Small Sanyang carriers in Altay, Xinjiang can't get a health certificate. Those who are "three positive" for hepatitis B virus may not apply for a health certificate. This is because hepatitis B virus can spread through blood and other body fluids, and it will cause damage to human liver. Carriers need to take some special protective measures in their lives to avoid the risk of infecting people around them.
