Abstract

Abstract

Objective To understand the epidemiological characteristics of influenza-like illness (ILI) cases and severe acute respiratory infection (SARI) cases in Taizhou, so as to provide a basis for scientific prevention and control strategies. Methods The basic information of ILI and SARI cases and throat swab specimens were collected from the sentinel hospital and 13 respiratory pathogens were detected by RT-PCR method.χ² test was used as statistical analysis method. Results From April 2012 to December 2019, with epidemic peaks in autumn and winter, the percentages of ILI visits (ILI%) and SARI visits (SARI%) were 7.27% and 2.44%, respectively. Finally, 956 ILI case specimens and 557 SARI case specimens were detected. The positive detection rates of the two types of cases were 50.84% (486/956) and 39.14% (218/557), separately. Streptococcus pneumoniae (SP), influenza virus (Flu), Haemophilus influenzae (HI) and Human rhinovirus (HRV) were the dominant pathogens in Taizhou city from April 2012 to December 2019, and their detection rates were 14.81%, 9.25%, 9.39% and 7.73%, respectively. The total mixed infection rate was 30.11% (212/704), which was mainly caused by SP complicated with other pathogenic infections. The positive rate of pathogen detection in the low-age group was higher than that in the high-age group, and the detection rate of children under 5 years old was 34.83% (χ²=54.47, P < 0.001). The detection rate of human coronavirus (HCoV) was 2.12%, with HCoV-OC43 subtype mainly (46.88%), and each subtype has no obvious seasonal distribution characteristics. Conclusions The incidence of comprehensive respiratory tract surveillance in sentinel hospitals in Taizhou City showed that the peak of the epidemic was in autumn and winter, and SP, Flu, HI, and HRV were main pathogens in this area. In the age group under 15 years old, the detection rate was higher. Comprehensive respiratory disease prevention and control measures should be taken for key populations.
