Objective To analyze the epidemic features and trends of plague in Manzhouli, China during 2001-2013, and to provide a basis for the development of plague prevention and control strategies and early warning. Methods Epidemiological methods were used to analyze plague surveillance data in Manzhouli during 2001-2013. Results A total of 1764 sera (including 1327 sera from Spermophilus dauricus) collected from 2001 to 2013 were examined, with special focus on 2004, 2005, 2007, 2008, 2010 and 2012 samples, of which 34 F1 antibody?positive S. dauricus sera were identified. Bacteriological tests of 2131 rodents and 1884 fleas found no signs of Yersinia pestis. Conclusion No signs of human plague were found in Manzhouli during 2001-2013, while indication of animal plague epidemic was discovered. There were substitution of plague host and invasion of Mongolian gerbil at the same time. The monitoring and precaution in the key areas should be strengthened to prevent the occurrence and epidemic of plague among humans.
