    To determine rates of both symptomatic and asymptomatic infection among ambulatory adults, we collected nasopharyngeal swabs, demographics, and survey information from 1477 adult visitors to a New York City tourist attraction during April-July 2016. Multiplex PCR was used to identify specimens positive for common respiratory viruses. 7.2% of samples tested positive; 71.0% of positive samples detected rhinovirus and 21.5% detected coronavirus. Influenza, respiratory syncytial virus, and parainfluenza were also detected. Depending on symptomatologic definition, 57.7-93.3% of positive samples were asymptomatic. These findings indicate that significant levels of asymptomatic respiratory viral shedding exist during summer among the ambulatory adult population.
