In November 2009, the National Center for Disease Control and Prevention (NCDC) issued a statement that the five hepatitis B tests will be cancelled and a hepatitis E test will be added to the health certificate. The health card is not for all people, only for the relevant employees, such as hotels, hotels, shopping malls, cafeterias and other public places staff, that is, in the health of employees in the blood test program no longer check the hepatitis B virus serological indicators, so hepatitis B patients can apply for a health card. Although hepatitis B patients can apply for a health certificate, but does not indicate that hepatitis B patients are recovered, or need to go to regular checkups to prevent the development of changes in the disease.
