ObjectiveTo ascertain characteristics of the pathogen spectrum and epidemiology with acute respiratory tract infection at monitoring point hospital of Shanghai, and provide a scientific basis for strategies and measures in prevention and control of the respiratory tract infectious disease.
MethodsThe nasopharyngeal swabs of ARTI patients were collected by interval sampling for pathogen identification, who visited the fever clinic at monitoring point hospital from November 2014 to March 2016. The epidemiological characteristics and pathogenic detection of acute respiratory tract infection were analyzed.
ResultsA total of 2 630 ILI cases were registered in this study, peaking in spring, summer and winter. There were 407 positive cases that were detected among 533 nasopharyngeal swabs, accounting for 76.36%. The top five isolating rates of the strains were influenza virus, klebsiella pneumoniae, staphylococcus aureus, nasal/enteric virus and adenovirus. The virus detection rate of different age groups was different (P < 0.05). The total positive rate and virus detection rate of those who had cough were higher than those without cough symptoms (P < 0.05).
ConclusionInfluenza virus infection proves to be the main cause of acute respiratory tract infection in Putuo District. Thus more attention and prevention and control measures should be strengthened with influenza. In the peak season, it is necessary to take measures to prevent aggregation epidemic of respiratory virus.
