Abstract: In 70 years since the founding of New China, with the great attention of the CPC Central Committee and the State Council and the joint efforts of all parties concerned, remarkable achievements have been made in China's public health and infectious disease prevention and control, especially in the field of emerging infectious disease prevention. Those efforts effectively enhance population’shealth and social stability and make important contributions to economic development. From the SARS outbreak in 2003 to human infection of H7N9 avian influenza in 2013, the emerging infectious diseases have become a major public health problem, increasingly capturing China and other countries’attention and concern.In order to effectively prevent emerging infectious diseases, the Chinese government has formulated and established a series of strategies, programs and guidelines and constructed a network system for disease surveillance. Through the establishment of the "four early" prevention and treatment Methods , early detection, early reporting, early isolation and early treatment, the haze of major new infectious diseases such as SARS and human avian influenza has been dispelled, leaving a significant record in the history of international epidemiology. This has pushed forward the goal of "healthy China".

Key words: Emerging infectious diseases, SARS, Human avian influenza, Public health, Prevention and control
