To analyze the epidemiological characteristics of severe acute respiratory syndrome corona virus 2 (referred to as SARS-CoV-2) and influenza viruses in Inner Mongolia Autonomous Region in 2023, and to provide a scientific basis for the prevention and control of acute respiratory infectious diseases in the region.
Collect the ILI surveillance data and nucleic acid detection data of influenza virus and SARS-CoV-2 from the first to 52nd week of 2023 in the whole district and describe and statistically analyze the percentage of ILI among outpatient cases and the epidemiological data of influenza virus and SARS-CoV-2, statistical methods used were χ2 test.
A total of 166 307 cases of ILI were reported in sentinel hospitals from weeks 1 to 52 in 2023, and the total number of cases attended was 6 143 210, and the percentage of ILI in the number of cases attending outpatient emergency departments (ILI%) was 2.71%. ILI% was statistically different in different weeks (χ2=35 246.742, P<0.05) and different regions (χ2=71 475.341, P<0.05)were statistically different. A total of 25 680 ILI specimens were collected in the sentinel hospitals, and the nucleic acid positivity rate of SARS-CoV-2 was 11.75%, and the positivity rate was statistically different in different weeks (χ2=2 272.239, P<0.05), different age groups (χ2=1 012.19, P<0.05), different regions (χ2=114.624, P<0.05), and different genders (χ2=26.464, P<0.05) were statistically different. Influenza virus nucleic acid positivity rate was 12.77%, and the positivity rate was statistically different in different weeks (χ2=9 606.493, P<0.05), different age groups (χ2=717.307, P<0.05), and different regions (χ2=41.406, P<0.05).
COVID-19 infection and influenza are alternately prevalent in Inner Mongolia Autonomous Region from week 1 to 52 in 2023, and continuous monitoring of SARS-CoV-2 and influenza virus is needed to obtain more monitoring data to provide scientific data support for effective prevention and control of acute respiratory infectious diseases.
