PRIMARY outcome

Timeframe: 1-5 days during acute illness (not after day 5 of illness)

Population: Analysis was per protocol based on the number of children enrolled by genotype and completed nasal washes at first visit.

Interferon a2 was measured from nasal lavage samples by Luminex multiplex assay.
