10 States Where Respiratory Illness Is Spreading Fastest, CDC Warns

The agency's data shows cases of COVID-19, RSV, and the flu are spiking the most here.

The excitement of the holiday season alone can be enough to make anyone feel worn out. But the busy travel and gathering season also comes with some familiar unwelcome guests: the flu, respiratory syncytial virus (RSV), and COVID-19. Most people spend the colder months trying to keep an eye out for any potential symptoms that could mean they're coming down with one of the viruses, especially as more people around us become sick. But now, new figures from the Centers for Disease Control and Prevention (CDC) show that respiratory illness is surging in many areas—including 10 states where "very high" activity levels mean they're spreading fastest.

National data from the agency as of Dec. 22 shows that more people are reporting symptoms of respiratory illness to their healthcare providers, which includes sore throat or a fever with a cough. Overall, 25 states were found to be at "high" or "very high" on the CDC's activity levels scale, which runs from one to 13

The latest report states that emergency room visits due to the flu are increasing nationwide, with positive test results for the virus increasing roughly 29 percent from the previous week. COVID-19 hospital admissions also remain high, and RSV-related visits are currently surging in other parts of the U.S. while previous hotspots see a decline, per CDC data.

Unfortunately, part of what makes the holidays so enjoyable could also be what drives up some of the risk of getting sick. Reported cases of the flu tend to begin surging at Thanksgiving and carry on through the season "because there's gatherings and that's when we see a peak," Francesca Torriani, MD, program director of the infection prevention, clinical epidemiology, and tuberculosis control units at the University of California San Diego Health, told USA Today.

"We're definitely seeing activity (and) it is widespread," Torriani told the paper, adding that "we are having a viral respiratory fest."

The figures also come nearly two weeks after the CDC released an alert highlighting an "urgent need" to boost immunization rates for respiratory viruses ahead of the winter season. The agency said the number of flu shots had decreased by about 7 million compared to last year, and only 17 percent of adults had received the latest COVID-19 vaccine.

Experts say those who are late in getting their shots will still see plenty of protectionary benefits if they seek them out now. "Given what we see currently, we would likely expect flu activity to continue increasing into January and possibly February, which would be similar to last year," Wesley Self, MD, professor of emergency medicine at Vanderbilt University Medical Center, told USA Today.

And as always, very familiar health precautions can also help decrease the likelihood of getting sick. "You want to make sure you have that protection, that high-quality mask, washing your hands, making sure you're updated on your vaccines, and always preparing for the highest risk person of the room," Darrien Sutton, MD, told ABC News.

But for now, some areas are still dealing with particularly strong viral surges. Read on for the states where respiratory illness is currently spreading fastest, according to CDC data.
