WASHINGTON: The flu season has arrived in full force across most U.S. states, driving a significant rise in illness rates alongside COVID-19 and respiratory syncytial virus (RSV), according to the latest Centers for Disease Control and Prevention (CDC) data. Influenza, in particular, is dominating respiratory cases, posing a serious public health concern as hospital visits climb.
Flu spikes amid seasonal activity
Last week, flu positivity surged to 18.7%, a sharp contrast from just 2.5% in November. Influenza A strains accounted for 98% of confirmed flu cases, leaving Influenza B at a minor 2%. The CDC’s tracking relies on reports of flu-like illnesses (fever, cough, sore throat) rather than laboratory-confirmed cases, capturing a broader range of respiratory diseases, including RSV and common colds.

COVID-19 trends show gradual increases
COVID-19 test positivity for the same week hovered at 7.1%, with a minor uptick in emergency room visits for positive cases at 1.2%. Hospitalization rates also rose to 2.2 per 100,000 people, reflecting a slight increase from prior weeks. As of December 23, vaccination rates for the 2024-2025 COVID season show only 20.9% of adults have been vaccinated, and around 10% of children received their shots.
RSV: A growing concern for young and older populations
RSV cases continue to climb, disproportionately affecting young children and seniors. Emergency room visits remain elevated, signaling the virus’s aggressive spread. The CDC reports that RSV vaccine uptake remains low among eligible groups. Only 44% of adults over 75 have received the vaccine, while vaccination rates for high-risk adults aged 60–74 stand at 32.8%.

Vaccination: A crucial step for protection
Health authorities recommend RSV vaccines for seniors over 75 and high-risk adults aged 60 to 74. Timely vaccination can significantly reduce the risk of severe illness and complications.
This season’s respiratory illness surge underscores the importance of staying vigilant, practicing good hygiene, and staying updated on vaccinations to protect yourself and your loved ones.
