To study the trend of influenza and the impact of coronavirus disease 2019 (COVID-19) in Kezhou, Xinjiang from 2013 to 2020. The data of influenza in Kezhou, Xinjiang from January 1, 2013, to December 31, 2020, were collected by the China Influenza Surveillance Information System to study the trend of ILI proportion, the distribution of influenza-like cases in different age groups, the positive cases and positive rate of influenza, and the trend of different influenza subtypes, and to analyze the impact of COVID-19 epidemic on influenza. The proportion of ILI in the Xinjiang Kezhou area was mainly children under 15 years old, and children under 5 years old accounted for the largest proportion. The proportion of ILI, the number of influenza-positive cases, and the influenza-positive proportion were mainly in winter and spring, especially in December and January each year. At the same time, this study found that the overall trend of H3N2 influenza in this region was on the rise, and the outbreaks in 2018 and 2019 were dominated by novel H1N1 and H3N2, respectively. The trend of influenza in Kezhou, Xinjiang is on the rise, and the prevention and control measures of COVID-19 have significantly reduced the data of influenza. It is necessary to strengthen the vaccination work and maintain the basic prevention and control measures of respiratory infectious diseases to prevent and control influenza more effectively.
研究 2013 年至 2020 年期间新疆克州流感和 2019 年冠状病毒病（COVID-19）的趋势。通过中国流感监测信息系统收集了 2013 年 1 月 1 日至 2020 年 12 月 31 日新疆克州的流感数据，研究ILI 比例趋势、不同年龄组流感样病例分布、流感阳性病例和阳性率以及不同流感亚型趋势，并分析 COVID-19 疫情对流感的影响。新疆克州地区 ILI 的比例主要是 15 岁以下的儿童，其中 5 岁以下儿童所占比例最大。ILI 比例、流感阳性病例数和流感阳性率主要出现在冬季和春季，尤其是每年的 12 月和 1 月。同时，本研究发现，该地区 H3N2 流感的总体趋势呈上升趋势，2018 年和 2019 年的暴发分别以新型 H1N1 和 H3N2 为主。新疆克州流感呈上升趋势，COVID-19 的防控措施显著降低了流感数据。有必要加强疫苗接种工作，保持呼吸道传染病的基本防控措施，以更有效地防控流感。
