Now, AIDS, TB and other infectious diseases pose serious threats to public health, while more and more people continue to die from non-infectious diseases. Experts estimate that China now has 600,000 HIV/AIDS victims, and the number is increasing by 30 percent annually. However, there is still no effective prevention and control system to fight the deadly disease.
　　Meanwhile, people lack knowledge of the cause, spread and development of epidemic, vermin-cause, occupational diseases and many other non-infectious diseases. This makes control work more difficult. Official figures show that 90 percent of total deaths are caused by chronic and non-infectious diseases, such as tumors and blood diseases of the heart and brain.
　　At the same time, China is becoming an “aging society”, with 10 percent of its population over 60. This will also bring many public health problems which will need effective supervision and study.
　　The establishment of the center is expected to play a leading role in disease supervision, the officials said. The center will also cover the hygienic supervision of food, workplaces, schools and other public places. Prevention and control programs against various diseases will be created by the center, which also will be in charge of evaluating the development of the program. All nations vaccination programs will be done by the center and its branches, and all the biological products for prevention will be under the control and management of the center. More health education and improvement work will be done by the center in the field of diseases prevention.
