Epidemiology Rhinoviruses can be detected year-round; however, the incidence of rhinovirus is higher in the autumn and winter, with most infections occurring between September and April in the northern hemisphere. The seasonality may be due to the start of the school year and to people spending more time indoors thereby increasing the chance of transmission of the virus. Lower ambient temperatures, especially outdoors, may also be a factor given that rhinoviruses preferentially replicate at 33 °C (91.4 °F) as opposed to 37 °C (98.6 °F). Other climate factors such as humidity may influence rhinovirus seasonality. Young children (<5 years old) experience a high rate of infection which can be detected in community surveillance studies of children up to 34% of the year.
