We assessed the impact of the H1N1 influenza pandemic on acute respiratory infection in young children from low-income families in Brazil. Influenza (specifically H1N1) detection in acute respiratory infection quintupled during the pandemic and, during its peak, it was associated with 30% of all acute respiratory infection visits to the emergency department. H1N1 was also associated with increased risk of hospitalization and coinfection.
