To assess influenza symptoms, adherence to mask use recommendations, absenteesm and presenteeism in acute care healthcare workers (HCWs) during influenza epidemics.
The TransFLUas influenza transmission study in acute healthcare prospectively followed HCWs prospectively over 2 consecutive influenza seasons. Symptom diaries asking for respiratory symptoms and adherence with mask use recommendations were recorded on a daily basis, and study participants provided midturbinate nasal swabs for influenza testing.
In total, 152 HCWs (65.8% nurses and 13.2% physicians) were included: 89.1% of study participants reported at least 1 influenza symptom during their study season and 77.8% suffered from respiratory symptoms. Also, 28.3% of HCW missed at least 1 working day during the study period: 82.6% of these days were missed because of symptoms of influenza illness. Of all participating HCWs, 67.9% worked with symptoms of influenza infection on 8.8% of study days. On 0.3% of study days, symptomatic HCWs were shedding influenza virus while at work. Among HCWs with respiratory symptoms, 74.1% adhered to the policy to wear a mask at work on 59.1% of days with respiratory symptoms.
Respiratory disease is frequent among HCWs and imposes a significant economic burden on hospitals due to the number of working days lost. Presenteesm with respiratory illness, including influenza, is also frequent and poses a risk for patients and staff.

评估流感流行期间急性护理医护人员（HCW）的流感症状、口罩使用建议的依从性、缺勤和出勤。
TransFLUas 流感传播研究前瞻性地在连续两个流感季节中对 HCW 进行了前瞻性随访。症状日记每天记录呼吸道症状和口罩使用建议的依从性，研究参与者提供鼻中隔鼻拭子进行流感检测。
共有 152 名 HCW（65.8%为护士，13.2%为医生）被纳入：89.1%的研究参与者在研究期间报告至少有 1 种流感症状，77.8%患有呼吸道症状。此外，28.3%的 HCW 在研究期间至少缺勤 1 天：其中 82.6%的缺勤是因为流感样疾病的症状。在所有参与的 HCW 中，67.9%在 8.8%的研究日工作时患有流感感染症状。在 0.3%的研究日，有症状的 HCW 在工作时会排出流感病毒。在有呼吸道症状的 HCW 中，74.1%在有呼吸道症状的 59.1%的日子里遵守了在工作时戴口罩的政策。
呼吸道疾病在 HCW 中很常见，由于缺勤天数的增加，给医院带来了巨大的经济负担。患有呼吸道疾病（包括流感）的出勤也很常见，对患者和工作人员构成风险。
