* National disease Reporting System (NDRS): The system covers the entire population (1.3 billion persons) living in all the provinces, prefectures, and counties that make up mainland China. Thirty-five communicable diseases are reportable under this system.
* Nationwide disease Surveillance Points (DSPs): This surveillance system, comprising 145 reporting sites selected by stratified cluster random sampling, covers a 1% representative sample of China's population.
* Surveillance system for specific infectious diseases, occupational diseases, food poisoning, etc.
