Objective To analyze the imported chikungunya fever cases detected at the frontier ports of Guangdong Entry-Exit Inspection and Quarantine Bureau and to provide a basis for control of imported infectious diseases. Methods Surveillance was conducted in the entry passengers at the frontier ports of Guangdong Entry-Exit Inspection and Quarantine Bureau from 2008 to 2011, and epidemiological investigation was carried out in the feverish passengers from the epidemic area of chikungunya fever. The blood samples of suspected cases were collected for laboratory test, and the information of positive cases were analyzed. Results Eleven cases of chikungunya fever, all from the epidemic area of ehikungunya fever, were detected; of these imported cases, 9 were in the period of disease while passing the frontier ports, and the other 2 were in incubation period and had an onset in the observation period after entry. The mean age of the 11 cases was 40.2 years; most of them were young and middle-aged males. The primary detection method was fever surveillance. There were no secondary cases.
