Summer is usually linked with sunshine, barbecues, and beach days—not runny noses and sore throats. But despite what many people think, cold and flu viruses don’t take the summer off. While it’s true that many viruses become less active during the warmer months, some still circulate and cause illness—even now.
According to new federal data released Friday, COVID-19 cases are once again on the rise across most U.S. states, with emergency room visits increasing across all age groups.
So, What’s Going Around Right Now?
Colds, Flu, and RSV
The CDC says medical visits for COVID-19, flu, and RSV (respiratory syncytial virus) remain low overall. Flu activity is declining, and RSV rates have stayed steady. But COVID-19 is a different story—it’s trending upward in many areas.
Wastewater monitoring suggests “moderate” COVID activity nationwide. The most common strain currently is the XFG variant, nicknamed “stratus,” which can cause a particularly sharp sore throat often described as feeling like “razor blades.” The World Health Organization has labeled it a “variant under monitoring.”
Other Summer Viruses
In addition to COVID-19, other common viruses during the summer include:
-
Hand, Foot, and Mouth Disease: Causes cold-like symptoms, along with mouth sores and skin rashes.
-
Norovirus (Stomach Flu): Causes nausea, vomiting, and diarrhea, and can spread rapidly, especially in group settings.
Should You Get a COVID-19 Booster Now?
If you’re generally healthy, timing matters. Experts suggest scheduling your booster shot a few weeks before big events like vacations or weddings. However, for most people, waiting until the fall may offer better protection ahead of expected winter surges.
How to Stay Healthy This Summer
The best prevention strategies haven’t changed:
-
Wash your hands regularly
-
Spend time outdoors when possible
-
Consider wearing a mask in crowded indoor spaces
-
Stay home if you’re feeling sick
Even during the dog days of summer, viruses can still find a way in—so a little caution can go a long way.
