Investigation of incidence of febrile respiratory illness and related hospital visits in local residents aged 15 years or older in Shunyi district, Beijing, 2020

  Objective  To understand the incidence of febrile respiratory illness (FRI) and relate4d hospital visits in local residents aged ≥15 years in Shunyi district, Beijing, in 2020.

  Methods  The catchment area of Shunyi Hospital was used as the investigation area, and multi-stage sampling was conducted to select local residents aged ≥15 years for an online survey. The incidence rate of FRI and related hospital visit rate were calculated and adjusted according to the population composition in Shunyi. The differences in incidence rate and related hospital visit rate among the residents with different characteristics were compared. Univariate and multivariate logistic regression analyses were conducted to explore the factors influencing the hospital visits.

  Results  A total of 2723 local residents aged ≥15 years in Shunyi were surveyed. In 2020, the self-reported incidence rate of FRI was 13.5% and then adjusted to 12.8%. There were significant differences in FRI incidence among the residents with different occupations, self-reported health status and history of underlying disease (P<0.05). Of the residents who reported FRI, 221 visited hospitals, the hospital visit rate was 60.2% and then adjusted to 57.7%. The multivariate Logistic regression study revealed that age, occupation, underlying disease and post-illness symptoms (chill and dry cough) were the main influencing factors of hospital visits

  Conclusion  In the context of global COVID-19 pandemic and fighting against imported and reemerged COVID-19 in China, the incidence of FRI in the local residents in Shunyi was high and related hospital visit increased significantly. The results of this study can be used as reference for the disease burden evaluation, prevention and control of FRI.
