14 States Where Respiratory Illness Is Spreading Fastest Post-Holidays, CDC Warns

The holiday season can often be one of the brightest times of the year as families and friends get together to celebrate. Unfortunately, these anticipated reunions also happen during what's typically high season for contagious viruses including the flu, respiratory syncytial virus (RSV), and COVID-19. For some, this means settling into the new year just as the first signs and symptoms of getting sick appear. And according to data from the Centers for Disease Control and Prevention (CDC), there are more than a dozen states where respiratory illness is now spreading at a "very high" rate.

On Dec. 29, the agency updated its weekly activity levels report that keeps track of the rate of patients seeking medical care or being admitted to the hospital while reporting symptoms of respiratory illness, including a sore throat or a fever with a cough. While it cautioned that a lag in reporting over the holidays could affect numbers after data is backfilled, 32 states were ranked as "high" or "very high" on the CDC's scale that runs from one to 13.

Figures from the week ending on Dec. 23 also painted a grim picture, noting a 12 percent jump in emergency room visits, a 17 percent rise in hospitalizations, and an increase in positive test results for all three viruses at the national level, CNN reports. But some experts pointed out that the current spike might get yet another boost.

"Remember, all of these numbers are before people got together for the holidays," Peter Hotez, MD, PhD, dean of the National School of Tropical Medicine at the Baylor College of Medicine, told CNN. "So don't be disappointed or surprised that we even see a bigger bump as we head into January."

The spike also comes amid growing concern that the general population might be more susceptible to the viruses as immunization rates for respiratory illnesses remain relatively low across the board.

"We have, as a population, underutilized both influenza and the updated COVID vaccines, unfortunately," William Schaffner, MD, an infectious disease expert at Vanderbilt University, told CNN. "But it's not too late to get vaccinated because these viruses are going to be around for a while yet."

However, despite surging numbers, there are still ways to keep yourself and others safe. "Of course, I continue to recommend vaccination, prudent use of the mask by high-risk people, and should you become sick, do not go to work and spread the virus further," Schaffner told CNN. "Call your health care provider, because you may have some treatment available that will get you healthier sooner."

But even though national numbers are increasing, some areas are seeing even worse spikes than most. Read on for the states where respiratory illness is currently spreading fastest, according to data from the CDC.
