16 States Where Respiratory Illness Is Spreading Fast, CDC Warns

The agency says cases of COVID-19, RSV, the flu, and colds are surging in these places.

The world has changed in many lasting ways since the COVID-19 pandemic began in 2020. But while we might be in the habit of carrying around hand sanitizer or being extra vigilant about identifying potential symptoms, the fact that seasonal viruses still spread around is no different today. Coronavirus has joined the all-too-familiar list alongside the flu, respiratory syncytial virus (RSV), and the common cold as potential public health hazards. And now, the Centers for Disease Control and Prevention (CDC) warns that respiratory illness is spreading fast in more than a dozen states.

The latest data considers patients who report to their doctor or the emergency room with respiratory illness symptoms, including fever with a cough or a sore throat. As of Dec. 7, 16 states were listed as either "high" or "very high" compared to normal conditions throughout the year, earning activity level scores of eight or higher on a scale from one to 13.

Unfortunately, numbers appear to be trending upward across the board in some cases. On Dec. 8, the CDC said positive tests for COVID-19 and the flu were increasing nationally, as well as emergency room visits for the two illnesses. Meanwhile, the same figures for RSV appear to have flatlined or decreased slightly compared to the previous week.

The latest spike also comes as the agency continues to track a COVID-19 variant called JN.1 that currently makes up 15 to 29 percent of all cases in the U.S., according to a Dec. 8 update. The offshoot of the BA.2.86 omicron subvariant was first discovered in September and is now the fastest-growing nationwide. The CDC adds that the surge indicates it's either more transmissible or better at evading peoples' immune systems, but there is no sign that the viral offshoot causes more severe illness.

Some experts caution that the current surge could still be related to a post-pandemic public susceptibility to the viruses after doing away with heightened health precautions, citing a drastic spike last year. "It may take some time for viral levels and the immunity dynamic to level out," Karen Acker, MD, a pediatric infectious diseases specialist at New York–Presbyterian Komansky Children's Hospital, told Fortune. "This may be another bad year."

But while the latest numbers may come as a bit of a shock, the same precautions can still work to keep you healthy.

"Everything that we're hearing about it is not any new virus or new pathogen, it is the common things that we see every season that perhaps coming together," Philip Huang, MD, director of Dallas County Health and Human Services, told ABC News. "The preventive things are all the same, you know, stay home if you're sick, wash your hands, cough into your sleeve, don't rub your eyes, nose and mouth, get up to date on the vaccinations."
