Hospitalizations for severe acute respiratory syndrome (SRAG) caused by respiratory syncytial virus (RSV) and influenza have risen across Brazil, according to the latest InfoGripe bulletin from Fiocruz covering epidemiological week 22 (May 31‑June 6). Eleven states – Acre, Alagoas, Amapá, Paraná, Pará, Rio Grande do Norte, Rio Grande do Sul, Roraima, Santa Catarina, Sergipe and São Paulo – show SRAG incidence at alert, risk or high‑risk levels, with a trend of growth in the past two weeks. Twelve additional states, including Amazonas and Rio de Janeiro, remain in alert or risk categories but show signs of stabilising or declining cases.
The bulletin notes that children under four are the most affected group, with RSV accounting for roughly half of laboratory‑confirmed cases, while rhinovirus and influenza A also contribute significantly. Increases in influenza‑related hospitalizations have been observed in several regions. Health authorities recommend frequent hand washing, mask use in crowded indoor settings and isolation of symptomatic individuals, especially those in high‑risk groups, to curb further spread.
