Input: Background-Healthcare-associated transmission of respiratory viruses is a concerning patient safety issue. Design-Surveillance for influenza virus among a cohort of healthcare workers (HCWs) was conducted in a tertiary care children's hospital from November 2009 until April 2010, using biweekly nasal swab collection. If a subject reported respiratory symptoms, an additional specimen was collected. Specimens from ill HCWs and a randomly selected sample from asymptomatic subjects were tested for additional respiratory viruses by multiplex PCR. Results-From 170 enrolled subjects, 1404 nasal swabs were collected. Influenza circulated at very low levels during the surveillance period and 74.2% of subjects received influenza vaccination. Influenza was not detected in any specimen. Multiplex respiratory virus PCR analysis of all 119 samples from symptomatic subjects and 200 specimens from asymptomatic subjects yielded a total of 42 positive specimens; 7 (16.7%) in asymptomatic subjects. Viral shedding was associated with report of any symptom (OR 13.06, p<0.0001,) and younger age (OR 0.96, p=0.023, 95% CI 0.92-0.99) when controlled for gender and occupation of physician or nurse. After the surveillance period, 46% of subjects reported working while ill with an influenza-like illness during the previous influenza season.
