Abstract:
Objective To analyze the status of influenza A and B virus infection in patients admitted to Shanghai Children's Medical Center Affiliated to Shanghai Jiao Tong University School of Medicine from 2022 to 2023,and to provide scientific basis for the adjustment of influenza prevention and control measures in this area.Methods The positive status of influenza A and B virus antigen and nucleic acid were analyzed to deter-mine the prevalence and dominant types of influenza in 2022-2023.The peak of influenza A virus infection in 2023 was analyzed by antigen detection and nucleic acid detection,and the positive rates of influenza A virus detection in patients with different genders and ages were compared.Results In 2022 and 2023,the majority of patients were infected with influenza A virus.There was no significant difference in the positive rate of in-fluenza A virus antigen and nucleic acid detection between male and female patients(P>0.05).The positive rates of influenza A virus antigen and nucleic acid detection in patients of different ages were statistically sig-nificant(P<0.05).Compared with other age range,the positive rate of influenza A virus antigen and nucleic acid detection was the highest in patients>5-10 years old.From February to December 2023,the positive rate of influenza A virus nucleic acid detection(50.91%)was significantly higher than that of influenza A vi-rus antigen detection(28.73%),and the difference was statistically significant(P<0.05).Conclusion There is no influenza virus infection peak in 2022,and there are two influenza A virus infection peaks in 2023.The positive rates of influenza A virus antigen and nucleic acid detection are different due to different detection methods.
