Flu Detections Increased in Colorado and Louisiana

The US CDC's Weekly US Influenza Surveillance Report for Week #47 for 2025 recently offered these insights regarding respiratory disease activity, including Influenza.

The CDC states that 'seasonal influenza activity remains low nationally but is increasing in a few states, such as Colorado and Louisiana, primarily among children and young adults.'

Additionally, the percent positivity for Influenza and the percentage of outpatient visits for respiratory illness and emergency department visits for Influenza among pediatric age groups increased this week.

And the timing of these increasing activities is similar to that of several past flu seasons, with peaks expected during early 2026.

The best news posted by the CDC on December 1, 2025, is that no influenza-associated pediatric deaths occurring during the 2025-2026 season have been reported to the CDC.

From a disease prevention option, the CDC says vaccine manufacturers have projected that they will supply the United States with as many as 154 million doses of flu vaccine for 2025-2026. Most of the projected influenza vaccine supply produced this influenza season does not contain thimerosal as a preservative.

These flu shots are generally available at community pharmacies.
