BACKGROUND AND OBJECTIVE
Health-care workers (HCWs) are at higher risk of acquisition and transmission of respiratory virus infections. Nosocomial transmission of influenza has been documented but whether this is so for other respiratory viruses has not been assessed.
METHODS
Epidemiological, clinical and viral laboratory surveillance was carried out on HCWs presenting with acute respiratory infection in a university hospital.
RESULTS
Over a 2-year period, 203 subjects were recruited: rhinovirus was the most frequently detected virus (37.7% in flu negative samples) and influenza A/B was positive in only 12.3% of subjects. Only 19.7% of HCWs were immunized against influenza. High detection of rhinovirus occurred even during the peak of the influenza season and half of the infected subjects reported an influenza-like illness.
CONCLUSION
Rhinovirus infection occurred frequently in this study population and probably contributes to influenza misdiagnosis. Educational interventions about different viruses causing respiratory symptoms and an increase in standards of infection control besides influenza immunization among HCWs is needed.
背景与目的
医护人员感染和传播呼吸道病毒的风险更高。流感的医院内传播已有记录，但其他呼吸道病毒是否如此尚未评估。
方法
对一所大学医院中出现急性呼吸道感染的医护人员进行了流行病学、临床和病毒实验室监测。
结果
在两年期间，招募了203名受试者：鼻病毒是最常检测到的病毒（流感阴性样本中占37.7%），甲型/乙型流感仅在12.3%的受试者中呈阳性。只有19.7%的医护人员接种了流感疫苗。即使在流感季节高峰期，鼻病毒的检出率也很高，一半的感染受试者报告有流感样疾病。
结论
在该研究人群中，鼻病毒感染频繁发生，可能导致流感误诊。除了医护人员接种流感疫苗外，还需要开展关于引起呼吸道症状的不同病毒的教育干预措施，并提高感染控制标准。
