Introduction: The Influenza virus, one of the biggest public health challenges in the world, causes recurrent epidemics with acute respiratory infections that present manifestations that vary from mild conditions to fatal complications. Objectives: To characterize the epidemiological profile of hospitalized patients with Severe Acute Respiratory Syndrome (SARS) caused by Influenza Virus in the Northwestern region of São Paulo state, Brazil. Additionally, to verify the seasonality of influenza and the prevalence of the Influenza virus in the population of this region Additionally, to verify the flu seasonality and the Influenza virus prevalence in the population of this region. Methods: A cross-sectional retrospective study was carried out. Data from patients admitted to hospitals in the Northwestern region of the state of São Paulo, Brazil, from January to December 2018 were collected. Results: Results of 1712 samples were analyzed. Of these, 430 (25%) were positive for the influenza virus, being 417 (97%) positive for Influenza A and 13 (3%) positive for Influenza B. According to age group, 53.7% were from patients of risk group. Of these, 418 samples (24.4%) were from elderly people (over 60 years old) and 501 (29.3%) samples from children under five years old. It was important to point out that 89% of the positive samples were from unvaccinated patients. Conclusion: In conclusion, there was a predominance of the Influenza A virus in the elderly and children, both considered important risk groups. Furthermore, the importance of vaccination to reduce positive cases was highlighted. Early detection and identification can provide effective treatment; reducing hospitalization time and costs, and minimizing the risk of progression to severe cases and death. It is worth emphasizing the importance of prevention measures that must be maintained and strengthened, especially, vaccination.References
