We describe a patient with confirmed novel H1N1 (swine-like) influenza A virus who had daily nasal swabs tested during oseltamivir therapy. Nasal shedding remained positive for 2 days and became negative on day 3. This report presents the first available data on the kinetics of shedding of this novel virus under antiviral therapy.
