Objective: To describe the clinical aspects of Influenza A (H1N1) pdm09 in Brazil by geographic region, during the pandemic that occurred between 2009 and 2010. Method: This is a descriptive quantitative study. Data were collected from information from the Notifiable Diseases Information System (SINAN), using the Tabnet web tab on the DATASUS website. As inclusion criteria, data recorded during the period 2009 and 2010 were considered; only confirmed cases; and data available for the five Brazilian regions. Results: The region of Brazil with the highest number of confirmed cases of influenza A (H1N1) pdm09 during the pandemic period was the South. The most affected age group varied between regions, but in general, it was predominant in young people and adults. In all locations, the sex with the most confirmed cases was female. The South was also the one with the highest percentage of evolution to SRAG, however, it was the Southeast that had the highest number of SRAG requiring hospital admissions. Despite having the highest number of cases, the South region also had the highest percentage of cure. Conclusion: Brazil suffered great impacts from the influenza A (H1N1) pandemic. Thousands of people were affected. In general, unlike other common flu viruses, the influenza A virus affects younger people and female individuals in all Brazilian regions.
