U.S. Flu Season Starts Early as Influenza A Spreads Across All 50 States

Key points

• CDC data shows flu activity rising in all 50 states, with the highest levels on the West Coast.
• Influenza A, specifically the H1N1 subclade, accounts for 97% of confirmed cases.
• Wastewater data indicates the earliest flu onset in at least four years.
• Health experts recommend getting vaccinated by the end of October, with earlier vaccination advised due to the early start.
• Vaccination is especially critical for high-risk groups, including children, older adults, and those with chronic conditions.

Background

Previous coverage in September and early October highlighted early flu activity in specific regions, such as the San Francisco Bay Area and Washington state, with rising hospitalizations and emergency room visits. These earlier reports emphasized the need for early vaccination and noted the concurrent rise in COVID-19 cases.

How outlets are covering it

USA TODAY and WJAR both emphasize the early start of flu season and the importance of vaccination. USA TODAY provides detailed data on the spread and the dominant strain, while WJAR focuses on the types of vaccines available and the timing for vaccination. WXYZ 7 News Detroit adds context on the CDC's Respiratory Disease Outlook report, which predicts similar peak hospitalizations for COVID-19, flu, and RSV as last season. All sources agree on the need for early vaccination, but USA TODAY and WJAR provide more specific data on the current situation, while WXYZ 7 News Detroit offers a broader outlook on the respiratory season.

Why it matters

The early start of flu season could lead to a more severe respiratory season, with increased hospitalizations and a strain on healthcare systems. Early vaccination is crucial to mitigate the impact, especially for high-risk groups. The concurrent rise in COVID-19 and RSV cases adds to the complexity of the respiratory season, making vaccination even more important.

What to watch

Health officials are urging people to get vaccinated as soon as possible, with the end of October being the target date. The CDC and other health organizations are monitoring the situation closely and will provide updates as the season progresses. People should stay informed and take preventive measures, such as handwashing and mask-wearing, to reduce the spread of respiratory viruses.
