ABSTRACT

Objective To analyze the detection results of 75 suspected type A influenza cases and to understand the distribution situation of influenza patients to provide the guidance for its early prevention and control .Methods The nasopharyngeal swabs specimens from 75 patients with suspected type A influenza were detected for understanding the viral infection situation by real‐time fluorescent quantitative PCR .Results In the specimens of 75 suspected patients ,13 cases with type A influenza virus were detected out ,in which 9 cases were the H1N1 subtype ,mean age > 50 years old .The temporal distribution was 3 cases in March 2013 ,1 case in April ,7 cases in January 2014 and 2 cases in February .No H7N9 subtype was detected out .Conclusion Real‐time fluores‐cent quantitative PCR has the characteristics of rapidness and high accuracy .The winter is the high onset season of flu ,elderly pa‐tients are susceptible to influenza virus .The monitoring and early treatment should be strengthened .
