Influenza cases are continuing to rise, reaching levels of activity not seen in the United States in 15 years, according to the Centers for Disease Control and Prevention (CDC).
A key measure of flu activity—the percentage of doctor visits prompted by flu-like symptoms—climbed significantly last week. The latest data, released Friday by the CDC, shows this figure surpassing the peak of any winter flu season since 2009-2010, when the swine flu pandemic spread across the country.
While other viral infections can sometimes mimic the flu, COVID-19 cases appear to be declining based on hospital reports and CDC projections. Additionally, data suggests that respiratory syncytial virus (RSV) cases have been decreasing nationwide.
