Circulation of respiratory viruses is normally highest in the fall and winter. For the purposes of reporting and comparisons over time and between viruses, the respiratory season typically runs from late August of the current year to late August of the following year. The current season, 2024-2025, starts on August 25, 2024 and ends on August 23, 2025. Additional information on respiratory season, and a full calendar for the current season, can be found on the Data Notes page.
Respiratory virus data included in the interactive data application is up-to-date as of November 9, 2024. Among its new features, the dashboard now includes RSV Severe Outcomes data.
