Objective To understand the epidemic situation of influenza in Longyan City, analyze epidemic trends, master epidemic information and provide basis for making targeted prevention and control measures. Methods Viral isolates and strains were collected from pharyngeal swab specimens of typical influenza-like cases in sentinel hospitals and some of the city’s flu and outbreaks. Results A total of 33 samples of 545 isolates were isolated from the samples. No positive isolates were detected in other months except in November and December. Among them, the isolates were isolated from February to April and from July to September. In 2008, H1N1, H3N2 and B strains were also reported in the population, of which B type was the most (63.0%). No influenza outbreak was found in our city in the whole year. Conclusion Influenza is endemic in our city all year round, and is more active in winter, spring and autumn. Influenza surveillance and disease prevention and control should be strengthened.
