Despite having the world's largest Web-based reporting network for infectious diseases, China faces a myriad challenges to prevent them from spreading largely because of the high incidence of new infections as well as the nation's mass population migration, a top health official said on Wednesday.

Li Bin, head of the National Health and Family Planning Commission, made the remarks during the ongoing bimonthly session of the National People's Congress Standing Committee. At the session, she made a report on how the government has implemented the Law on Prevention and Treatment of Infectious Diseases.

"The government will improve monitoring and warning systems to ensure early discovery, diagnosis, reporting and treatment of infections. More efforts must be made to combat diseases including HIV/AIDS, tuberculosis and hepatitis B," she said.
