Abstract:
Objective:The objective of this study was to analyze the disease burden of influenza in schools and child care settings in rural areas of Hangzhou.
Methods:Hospital visit influenza cases aged 3-17 years in hospitals that reported based on influenza surveillance system from 2016 to 2018 in Chun′an county, Hangzhou city were selected as study subjects and a total of 294 confirmed cases of influenza were selected using system sampling method. Questionnaires were designed to investigate the basic information and data on inpatients and outpatients among, health care and life quality, etc.. Direct and indirect economic burden and disability adjusted life year (DALY) were analyzed and compared among different age groups.
Results:The mean age of investigated subjects was (8.88±3.92) years. A total of 143 (48.64%) investigated cases were male. In total of 283 (96.26%) cases were outpatients. The total economic burden was 124 743.95 CNY. The mean economic burden was 424.30 CNY per person. The mean direct and indirect economic burden was 361.33 and 62.97 CNY per person respectively. The difference of the mean direct, indirect and total economic burden per person between different age group was statistically significant (P<0.001). The 3-5 years age group showed the highest economic burden with the median value of direct, indirect and total economic burden per person being 276.24, 50.98 and 321.26 CNY, respectively, while the 12-17 years age group showed the lowest values with 175.30, 26.54, 201.79 CNY, respectively. The DALY of 294 influenza cases was 1.18, and the median of burden strength was 3.21 DALY/thousand. The difference of the burden of strength between different age group influenza case was statistically significant (P<0.001), of which the 12-17 years age group showed the highest value with 4.25 DALYs/thousand while the 3-5 years age group showed the lowest value with 2.60 DALY/thousand.
Conclusion:The disease burden of influenza was heavy in schools and kindergartens in rural areas of Hangzhou city, with the cases aged from 3 to 5 years showing higher economic burden and cases aged from 12 to 17 years showing greater burden strength.
