Surveillance of respiratory viruses in severe acute respiratory infections in Southern Brazil, 2023-2024.

ABSTRACT: Severe Acute Respiratory Infection (SARI) is one of the leading causes of death worldwide, representing a significant public health challenge. Respiratory viruses are the primary pathogens responsible for these infections, and their ability to evolve and spread efficiently contributes to their widespread circulation. Here, we examined the epidemiological characteristics of SARI cases reported over one year (February 2023 To February 2024) in Rio Grande do Sul, the southernmost state in Brazil. Additionally, 4,000 negative specimens for influenza, Respiratory Syncytial Virus (RSV), and SARS-CoV-2, tested routinely, were evaluated by an expanded PCR respiratory panel (11 pathogens). During the study period, 14,816 SARI cases were reported: 3,396 cases due to SARS-CoV-2 infection, 2,329 To RS
