A series of public health interventions have been implemented to prevent the transmission of SARS-CoV-2 in China. However, the effect of non-pharmaceutical interventions to COVID-19 on the incidence of the influenza virus and Mycobacterium tuberculosis infections is not clear. In current study, we analyzed surveillance data on influenza and Mycobacterium tuberculosis from Henan Provincial People's Hospital in Zhengzhou, Henan province, China from 2019 to 2020. The monthly positive test rate for influenza and Mycobacterium tuberculosis to estimate transmissibility changes was calculated. The positive detection rate of influenza A declined significantly during the implementation of inventions in 2020, from a total positive rate of 17.69% in 2019 to 5.77% in 2020. Similarly, a 2.15% reduction in positive detective rate was seen for influenza B, from a total positive rate of 5.15% in 2019 to 3% in 2020. The positive rate curve of Mycobacterium tuberculosis measured by x-pert in 2020 remained above the curve in 2019 from March to June, and August, showing the rising trend under these precautions. Our study suggests that non-pharmaceutical public health interventions likely reduced influenza transmission significantly and have less effect on Mycobacterium tuberculosis transmission in 2020.
中国已实施了一系列公共卫生干预措施来预防 SARS-CoV-2 的传播。然而，非药物干预措施对 COVID-19 大流行期间流感病毒和结核分枝杆菌感染发病率的影响尚不清楚。本研究分析了 2019 年至 2020 年期间中国河南省郑州市河南省人民医院的流感和结核分枝杆菌监测数据。计算了流感和结核分枝杆菌每月阳性检测率以评估传染性变化。2020 年实施干预措施期间，流感 A 的阳性检出率显著下降，从 2019 年的总阳性率 17.69%降至 2020 年的 5.77%。类似地，流感 B 的阳性检出率也下降了 2.15%，从 2019 年的总阳性率 5.15%降至 2020 年的 3%。2020 年 X-pert 检测的结核分枝杆菌阳性率曲线在 3 月至 6 月和 8 月仍高于 2019 年的曲线，显示出在这些预防措施下呈上升趋势。本研究表明，非药物公共卫生干预措施可能显著降低了流感的传播，而对 2020 年结核分枝杆菌的传播影响较小。
