The US has seen its highest flu rates in at least 15 years, surpassing COVID-19 infections and hospitalizations for the first time since the beginning of the pandemic. According to the Centers for Disease Control and Prevention (CDC), this season is classified as having “high” severity across the U.S.
Flu cases and hospitalizations have been higher than any other week since before 2009, with most cases coming from influenza A strains. The season is peaking late compared to previous years, which typically peaked in early or late December. Unfortunately, there have been a number of deaths from flu this season, including over 4,000 people and 68 children.
The CDC attributes the high rates of flu to poor community protection due to low immunization rates and natural immunity, as well as virus characteristics, vaccine effectiveness, and increased human contact via travel and office work. Flu vaccination rates have declined since the COVID-19 pandemic, with adults showing historically low rates of 30% to 60%. Children’s vaccination rates have also dropped.
Low vaccination rates contribute to higher flu severity this season by leaving a larger portion of the population unprotected. However, genetic changes to the viruses may also play a role in making them more infectious and severe.
To reduce the risk of getting or spreading flu, people can get vaccinated, practice handwashing and disinfecting high-traffic surfaces, avoid contact with sick individuals, and prioritize self-care through exercising, eating healthy, and getting sufficient sleep. Those diagnosed with flu or experiencing symptoms should also avoid contact with others, especially in crowded spaces.
