In this study, we investigated the concentration of airborne influenza virus in daycare centers and influencing factors, such as common cold prevalence, air pollutants, and meteorological factors. A total of 209 air samples were collected from daycare centers in Kaohsiung and the influenza virus was analyzed using real-time quantitative polymerase chain reaction. Air pollutants and metrological factors were measured using real-time monitoring equipment. Winter had the highest positive rates of airborne influenza virus and the highest prevalence of the common cold, followed by summer and autumn. The concentration of CO was significantly positively correlated with airborne influenza virus. Daycare center A, with natural ventilation and air condition systems, had a higher concentration of airborne influenza A virus, airborne fungi, and airborne bacteria, as well as a higher prevalence of the common cold, than daycare center B, with a mechanical ventilation system and air purifiers, while the concentrations of CO, CO, and UFPs in daycare center A were lower than those in daycare center B. We successfully detected airborne influenza virus in daycare centers, demonstrating that aerosol sampling for influenza can provide novel epidemiological insights and inform the management of influenza in daycare centers.
在这项研究中，我们调查了日托中心空气中流感病毒的浓度及其影响因素，如普通感冒的流行情况、空气污染物和气象因素。我们从高雄的日托中心采集了 209 个空气样本，并使用实时定量聚合酶链反应分析流感病毒。使用实时监测设备测量空气污染物和气象因素。冬季空气中流感病毒的阳性率最高，普通感冒的发病率也最高，其次是夏季和秋季。CO 浓度与空气中的流感病毒呈显著正相关。采用自然通风和空调系统的日托中心 A 的空气中甲型流感病毒、真菌和细菌浓度以及普通感冒发病率均高于采用机械通风系统和空气净化器的日托中心 B，而日托中心 A 的 CO、CO 和 UFPs 浓度均低于日托中心 B。我们成功地在日托中心检测到空气中的流感病毒，表明对流感进行气溶胶采样可以提供新的流行病学见解，并为日托中心的流感管理提供信息。
