Abstract：Objective To analyze the epidemiological characteristics and seasonal variation of febrile respiratory syn-drome(FRS)in the elderly in Wuhan area.Methods A total of 468 specimens were collected from elderly patients with FRS in the sentinel hospitals in Wuhan from January 2021 to December 2023.The specimens were detected by multiplex real-time PCR,and the positive results were analyzed.Results Of 468 samples from elderly patients with FRS,254 positive specimens were detected,and the total positive rate was54.27%.There was no significant difference in the positive detection rate between male and female samples(P＞0.05).A total of 21 pathogens were detected in468 specimens,and the top 5 pathogens were Streptococcus pneumoniae(n=132,51.97%),Haemophilus influenzae(n=65,25.59%),influenza virus(n=32,12.60%),respiratory syncytial virus(n=29,11.42%)and rhinovirus(n=19,7.48%).There was no signifi-cant difference in the detection rates of the top 5 pathogens among patients with different ages and genders(P＞0.05).There was no significant difference in the detection rate of the top 5 pathogens from 2021 to 2023(P＞0.05).The top five patho-gens showed obvious periodic changes,and the detection rate was the highest in winter(P＜0.05).Among them,Streptococ-cus pneumoniae infection had obvious seasonal characteristics,with a high incidence in winter(P＜0.05).Conclusion Streptococcus pneumoniae,Haemophilus influenzae,influenza virus,respiratory syncytial virus and rhinovirus are the main pathogens in elderly patients with FRS in Wuhan area,and the infection peak season is winter.
