The summer COVID wave 2025 is here, and new CDC data shows a noticeable rise in cases across many parts of the United States. As temperatures climb and summer activities increase, so do the risks of infection. While the virus no longer causes mass shutdowns or panic like it once did, it’s clear that COVID-19 is far from over.
In this article, we’ll break down the latest data, highlight the states with the highest case increases, explain why cases are rising, and offer practical tips on staying safe during this seasonal wave.
According to the Centers for Disease Control and Prevention (CDC), COVID-19 cases have shown a steady rise throughout July 2025. While hospitalizations and deaths remain relatively low compared to earlier waves, weekly infection numbers have jumped by more than 30% in certain states.
Some key CDC takeaways include:
The CDC warns that this pattern is consistent with past summer surges, where more people gather indoors with air conditioning, travel for vacations, and attend crowded events like concerts and festivals.
The summer COVID wave 2025 is not hitting every state equally. Here are the top regions where COVID cases are rising the fastest, based on CDC reports and local health departments:
Florida tops the list, especially in South Florida and the Orlando area. With tourism at its peak and intense heat driving people indoors, test positivity has exceeded 15% in some counties.
Texas, especially cities like Houston, Austin, and Dallas, is seeing a sharp rise in emergency visits and COVID-related hospital admissions. Many counties report a 20–25% week-over-week increase in cases.
Los Angeles County and parts of the Bay Area are witnessing significant jumps in infections. Wastewater surveillance suggests rising community transmission.
With Las Vegas as a major tourist hub, Clark County is showing rising trends in COVID testing and hospitalizations.
Phoenix and Tucson have reported increasing numbers in both case counts and COVID-like illnesses.
Other states showing mild-to-moderate increases include New York, Illinois, Georgia, and North Carolina.
There are several reasons behind the summer COVID wave 2025.
The latest Omicron offshoot, KP.3, is more transmissible but appears to cause milder symptoms in most people. Still, it spreads quickly—especially in crowded indoor spaces.
Immunity from vaccines or previous infections may have waned. According to experts, many people haven’t received a booster in over a year, making them more vulnerable.
Summer is peak travel season, with millions flying, cruising, and attending crowded public events. This behavior contributes to faster viral spread.
Fewer people are wearing masks, testing before gatherings, or staying home when mildly sick.
It’s important to note that this wave, while real, is less severe than those in 2020–2022.
Hospitalization rates are lower, especially among vaccinated people
Most cases are mild, presenting with cold-like symptoms
Deaths are not rising dramatically, thanks to improved treatments and immunity
Still, the CDC stresses that certain groups remain at risk:
These groups are encouraged to take extra precautions, especially during high transmission periods.
While many symptoms feel like a common cold, the KP.3 subvariant has shown these common symptoms:
Loss of taste or smell is now less common with newer variants.
If you’re feeling sick or have been exposed to someone with COVID-19, the CDC recommends testing at home and isolating if you test positive.
The CDC continues to recommend getting updated COVID-19 boosters, especially if your last shot was more than 6–12 months ago.
A new updated vaccine targeting KP.3 and related variants is expected to roll out by September 2025. Officials say this updated shot will provide better protection during the expected fall and winter wave.
In the meantime:
Masks are no longer mandatory in most public spaces, but the CDC suggests voluntary masking in:
If you live in a state seeing a COVID spike, wearing a well-fitted N95 or KN95 mask in crowded places can significantly lower your risk.
Yes, but with precautions.
Travel during the summer COVID wave 2025 is not off-limits, but experts advise:
If you’re traveling with someone high-risk, be extra cautious and consider masking more consistently.
Here are simple steps to stay protected during this wave:
Health experts say this summer COVID wave 2025 may peak in early August and begin tapering off by mid to late August, depending on regional trends. However, a bigger fall surge could follow, especially as schools reopen and indoor activities increase.
The CDC plans to release updated guidelines in August, including mask advisories, booster eligibility, and more.
COVID-19 is no longer the deadly pandemic it once was, but it remains an ongoing public health concern. The summer COVID wave 2025, driven by the KP.3 subvariant and relaxed precautions, reminds us that the virus is still adapting.
Staying informed, taking small steps to reduce risk, and looking out for vulnerable communities can help everyone enjoy a safer summer.
Remember—simple actions like masking, testing, and staying home when sick still matter.
Stay safe, stay informed, and enjoy your summer responsibly.
