what kind of sickness is going around

Right now, in early January 2026, the main “sickness going around” in many places (especially the U.S.) is a very active flu wave driven by a new Influenza A H3N2 variant, alongside noticeable levels of COVID‑19, RSV, and some stomach bugs like norovirus.

Quick Scoop

What’s mostly going around?

  • Flu (Influenza A, H3N2 “subclade K”) is the big one this winter, with record or near‑record levels of illness and hospitalizations in many regions.
  • COVID‑19 activity is lower than past peaks but is rising again in wastewater and clinic data.
  • RSV is elevated, especially in young children, and contributing to crowded pediatric units.
  • Norovirus (“stomach flu”) is high in many areas, causing vomiting and diarrhea clusters in schools and care facilities.

In short: it’s a classic winter “multi‑virus” season, but the flu wave is the star of the show right now.

What the current flu wave looks like

  • Doctors are reporting an unusually early and intense flu season compared with typical years.
  • A mutated H3N2 strain (often called “subclade K”) is spreading quickly and is linked to more severe seasons, especially for older adults.
  • By late December, millions had already been sick, with tens of thousands hospitalized and thousands of deaths, including some in children, in the U.S. alone.

Common flu symptoms right now include:

  • Sudden high fever and chills
  • Cough, sore throat, and shortness of breath
  • Bad muscle aches, headache, and deep fatigue
  • Sometimes nausea, vomiting, or diarrhea, especially in kids

Other viruses in the mix

Even though flu is dominating, several other infections are “going around” at the same time.

  • COVID‑19
    • Rising in many regions, with levels described as “elevated” in wastewater in parts of the South, Northeast, and Midwest.
* Symptoms overlap with flu: fever, cough, fatigue, sore throat, sometimes loss of taste or smell.
  • RSV (Respiratory Syncytial Virus)
    • Elevated in many areas, especially affecting children under 4 and some older adults.
* Causes cough, wheeze, fast breathing, and feeding difficulty in babies.
  • Norovirus & other GI bugs
    • High activity, often causing outbreaks in schools, cruise ships, and nursing homes.
* Symptoms: sudden vomiting, watery diarrhea, stomach cramps, sometimes low fever.

How to think about “what’s going around” where you live

Because circulation varies by location, what’s going around for you depends on your region.

  • Many states and countries are reporting high or very high flu‑like illness levels right now.
  • Official dashboards list current trends for:
    • Flu and COVID‑19 (often via respiratory illness trackers).
* RSV and other respiratory viruses showing unusual spikes.

If you share where you are (country/state/city), a more tailored picture of “what kind of sickness is going around” in your area can be outlined based on current regional trends.

When to get checked out

You should seek urgent medical care or local emergency help if you or someone else has:

  • Trouble breathing or chest pain
  • Confusion, difficulty staying awake, or seizures
  • Lips/face turning blue or gray
  • Persistent high fever that does not come down with medicine
  • Signs of dehydration (very little urination, dizziness, dry mouth) in adults or children

For milder cold/flu‑like symptoms, many people are advised to:

  • Rest, hydrate, and use over‑the‑counter fever or pain medicines as directed.
  • Test for COVID‑19 if available, especially before seeing high‑risk people.
  • Call a doctor or nurse line if symptoms worsen or you’re in a high‑risk group (pregnant, older adult, chronic conditions, weak immune system).
