Epidemiological investigation and clinical symptom analysis of influenza among children in a hospital of Bengbu City from 2018 to 2019

  Objective  To analyse the epidemiological characteristics and clinical symptoms of influenza among children in a hospital of Bengbu City from 2018 to 2019 so as to provide basis for the prevention and treatment of influenza.  Methods  A total of 528 children diagnosed with influenza and hospitalised in the First People's Hospital in Bengbu from January 2018 to December 2019 were selected as the research objects. The medical history data of the children were reviewed and statistically analysed along with the epidemiological characteristics, clinical symptoms and laboratory tests.  Results  Among the 528 children with influenza, 21.3% had influenza A, 55.6% had influenza B and 23.1% had influenza A combined with influenza B. The peak age of influenza was 1-7 years old and 7-14 years old, and the lowest was among the 0-1 year old infants. Among them, the incidence rate of influenza increased with age, regardless of gender. No significant difference was noted in the incidence rate (P=0.326). The high incidence season of influenza among children was from November to December to March of the next year. The high incidence age of school-age children was 3-7 years old. The clinical symptoms of fever, sore throat, diarrhoea, headache and other clinical symptoms of children with influenza A were severe, the hospitalization time was long, the fever lasted for a long time and the complications were more. In addition, the test indexes of white blood cell, calcitonin and C-reactive protein were significantly increased (all P < 0.05).  Conclusion  The influenza outbreak of children in Bengbu City is seasonal. The number of patients with influenza B is more than those with influenza A and influenza A combined with influenza B. The clinical symptoms and organ damage of children with influenza A are significantly more serious than those with mixed influenza A and B. The hospitalization time and fever duration of children with influenza A are longer than those with influenza B and mixed infection.
