Objective The epidemic characteristics of malaria was investigated through analysis on malaria monitoring data from 2005 to 2014 in Nanping,Fujian so as to support the post-elimination monitoring on malaria.Methods The malaria epidemic data and all case reports from 2005 to 2014 were collected and analyzed for their epidemic characteristics.Results A total of 71 malaria cases was reported from 2005 to 2014 and all of them were imported cases.Among them,63.38% was from Africa,25.35% from Southeast Asia,and 11.26% from other domestic areas.The most of malaria patients were migrant workers who were infected abroad and the cases were dramatically increased since 2010 due to a significant return of migrant workers from African countries.At the mean time,domestic malaria cases were significantly decreased.These imported cases were concentrated on villages and towns where there were more migrant workers going abroad.Cases focused on the regions where many people went to Africa for jobs,such as Luxia Town (8 cases),Huangdun Community (5 cases),Sihe Community (4 cases) in Yanping area (28 cases,39.43%) and Street Ouning,Street Jian'an in Jianou city (23 cases,3239%).Conclusion There is an increasing challenge to prevent and control the imported malaria epidemics carried by migrant workers in Nanping City.It is necessary to reinforce the monitoring and management of imported malaria cases,especially focusing on migrant workers from African countries.
