摘要
Infectious diseases have caused and will continue to cause a significant impact on public health. Following the unprec- edented H7N9 outbreak in China in early 2013, the recent spreading of the Ebola virus in West Africa has once again placed the danger of infectious diseases in the public eye and has caused significant public alarm all over the world. Given the frequent recurrence of rapidly evolving pathogens, such as seasonal influenza viruses, and the sporadic introduction of novel pathogens, such as the 2003 SARS coronavirus in China, the prevention and control of infectious diseases has become a major global public health issue, which relies heavily on an effective surveillance strategy.
