High Rates of Flu and Other Respiratory Illnesses Reported Across the US “`
The holiday season saw a surge in influenza cases across the United States, with a significant number of states reporting high illness levels last week, according to the CDC.
CDC’s Carrie Reed described the situation as a widespread influenza outbreak.
Several pathogens cause symptoms like fever, cough, and sore throat, mimicking influenza. These include COVID-19 and RSV (respiratory syncytial virus), which, while commonly causing cold-like symptoms, can be serious for young children and the elderly.
However, current CDC hospitalization data and other indicators suggest influenza is currently the most prevalent virus, Reed stated. Multiple flu strains are contributing to the increase, with no single dominant strain, she added.
Pediatric hospitals have experienced high patient volumes since November due to RSV; however, influenza cases are now significantly increasing, according to Dr. Jason Newland, an infectious disease specialist at Nationwide Children’s Hospital in Columbus, Ohio.
He noted a substantial rise in cases, leading to increased hospital activity.
Where flu illnesses are the highest
One key indicator of flu activity is the percentage of doctor visits due to influenza-like illnesses. Last week’s percentage was comparable to the peak of last winter’s respiratory virus season, which occurred around the same time. Reed mentioned that holiday schedules might skew the data, as individuals may delay seeking medical attention.
Last week’s flu activity was most pronounced in the southern, southwestern, and western U.S. Lower levels were reported primarily in the northern Great Plains and New England.
To date, the CDC estimates at least 5.3 million flu illnesses, 63,000 hospitalizations, and 2,700 deaths, including at least 11 children.
The severity of this winter’s respiratory virus season remains uncertain. Newland indicated that so far, it appears relatively typical, at least among children.
How to protect yourself from seasonal illnesses
U.S. health officials recommend influenza vaccination for everyone aged 6 months and older, emphasizing that vaccination is still beneficial.
Practicing good hygiene is also crucial; avoid touching your eyes, nose, and mouth, as germs spread easily this way. Frequent handwashing with soap and water, cleaning frequently touched surfaces, and avoiding close contact with sick individuals are also recommended.
Other germs are being watched
The CDC is also monitoring a rise in norovirus illnesses, with 91 outbreaks reported in early December.
Another influenza virus, Type A H5N1 avian influenza, is also under surveillance. The CDC reported 66 human cases in the U.S. last year, but none in the past week.
These cases are described as sporadic, with minimal risk to the general public. Almost all cases have been linked to direct contact with infected animals, with no evidence of human-to-human transmission.
