Have you noticed a shift in the air lately? Maybe it’s the faint buzz of news reports or the subtle uptick in mask-wearing at the grocery store. Across the United States, whispers of a COVID-19 resurgence are growing louder, particularly along the West Coast. I’ve been keeping an eye on the numbers, and let me tell you, the latest data paints a picture that’s hard to ignore. It feels like we’re at a crossroads again, balancing caution with the urge to move forward.
A New Wave on the Horizon
The Centers for Disease Control and Prevention (CDC) recently dropped a report that’s got everyone talking. Wastewater viral activity—a fancy term for tracking virus traces in sewage—has jumped from “low” to “moderate” nationwide. If that sounds like a science fiction plot, it’s not. It’s one of the earliest ways we can spot a virus spreading before hospitals start filling up. And right now, the West Coast is lighting up like a warning signal on a dashboard.
Why does this matter? Because wastewater doesn’t lie. Unlike self-reported tests, it captures the virus’s spread in real-time, giving us a sneak peek into what’s coming. States like California, Nevada, and Hawaii are seeing some of the highest spikes, with Louisiana also flashing red on the CDC’s map. It’s not just a West Coast story, though—pockets of activity are popping up from Texas to South Carolina.
What’s Driving the Surge?
So, what’s behind this uptick? The short answer: a mix of factors. New variants are always part of the conversation when COVID-19 makes a comeback. The CDC hasn’t updated its variant tracker since mid-June, but when they did, they flagged strains like NB.1.8.1 and XFG as ones to watch. These aren’t household names yet, but they’re gaining traction, especially in places like China, where NB.1.8.1 has been stirring things up since early 2025.
The available evidence does not suggest additional public health risks from NB.1.8.1 compared to other Omicron descendants.

That’s reassuring, but here’s where my skepticism kicks in. Limited data from certain regions makes it tricky to gauge the full scope. If history’s taught us anything, it’s that viruses don’t respect borders, and what starts in one corner of the globe can ripple fast. The WHO’s keeping a close eye on these variants under monitoring, and so should we.
Beyond variants, human behavior plays a role. Summer travel, crowded events, and maybe a touch of pandemic fatigue are giving the virus room to spread. I can’t help but wonder: are we letting our guard down too soon? It’s a question worth pondering as we dig into the numbers.
Breaking Down the Data
Let’s get to the nitty-gritty. The CDC’s wastewater data is like a weather forecast for pandemics—it tells us where the storm’s brewing. Here’s what’s happening across the U.S.:
- West Coast Hotspots: California, Nevada, Utah, and Alaska are seeing elevated viral activity, with Hawaii and Louisiana at “very high” levels.
- Southern Spread: Texas, Mississippi, Alabama, and Florida are also reporting high case numbers.
- Midwest and Beyond: States like Indiana and South Carolina are showing upticks, though not as severe.
Interestingly, lab-based tests tell a slightly different story. While wastewater screams “moderate” activity, laboratory percent positivity—the share of tests coming back positive—is still classified as “low” but creeping upward. Emergency room visits for COVID-19 are also rising across all age groups. It’s like the virus is knocking on the door, but we’re not quite sure how loud it’ll get.
| Region | Wastewater Activity | Lab Positivity Trend |
| West Coast | High to Very High | Increasing |
| Southern States | High | Increasing |
| Nationwide | Moderate | Low but Rising |
The takeaway? We’re not in full-blown crisis mode, but the signs are there. It’s like spotting dark clouds on the horizon—you don’t grab an umbrella yet, but you keep one close.
How Does This Compare to Other Illnesses?
Here’s a bit of good news: overall respiratory illness levels in the U.S. are still “very low.” That includes flu and RSV, which are barely making a dent right now. So, while COVID-19 is picking up steam, it’s not dragging a parade of other viruses along with it—at least not yet.
But don’t let that lull you into complacency. The CDC’s data shows COVID-19 infections are either growing or likely growing in most states. It’s a reminder that this virus doesn’t play by our rules. One day it’s quiet, the next it’s knocking. Perhaps the most interesting aspect is how quickly things can shift—something I’ve learned from watching pandemics unfold over the years.
Policy Shifts and Public Health
The timing of this surge is particularly curious given recent changes in health policy. The Department of Health and Human Services has shaken things up since the new administration took over. For starters, they’ve scrapped the CDC’s vaccine advisory panel—17 members, gone. They’ve also pulled the plug on recommending COVID-19 vaccines for pregnant women and healthy kids, and even ordered mercury removed from flu vaccines.
These moves have sparked heated debates. On one hand, some folks see it as a push for more tailored health policies. On the other, critics argue it could weaken our defenses against a virus that’s clearly not done with us. I’m no policymaker, but I can’t help feeling a bit uneasy about the timing. A surge in cases paired with a shift in vaccine guidance? It’s like changing the tires in the middle of a race.
Public health strategies must evolve with the virus, but trust and transparency remain critical.

What does this mean for you? It’s a wake-up call to stay informed. Policies might shift, but the virus doesn’t care about politics. Keeping an eye on local trends and taking basic precautions—like masking in crowded spaces—could make a difference.
What Can You Do to Stay Safe?
Let’s talk practical steps. With cases climbing, especially on the West Coast, it’s time to dust off some of those pandemic habits we thought we’d left behind. Here’s a quick rundown of ways to protect yourself and your community:
- Monitor Local Data: Check wastewater or case trends in your area. It’s like checking the weather before a picnic.
- Mask Up When Needed: Crowded indoor spaces? A mask is your best friend.
- Stay Updated: Keep an eye on health updates, especially if you’re in a high-risk group.
- Boost Immunity: Good sleep, a balanced diet, and maybe a chat with your doctor about vaccines can go a long way.
I’ve found that small, consistent actions—like washing hands more often or avoiding that packed concert—can feel empowering. It’s about taking control in uncertain times. Plus, it’s a lot easier than dealing with a week in bed, right?
Looking Ahead: What’s Next?
So, where do we go from here? The CDC’s data suggests we’re in a growth phase, but it’s not time to panic. Think of it like a yellow traffic light—slow down, assess, and proceed with caution. The virus is still evolving, and so must our strategies. New variants like NB.1.8.1 and XFG might not be game-changers yet, but they’re a reminder that COVID-19 is a moving target.
In my experience, staying proactive is key. Whether it’s checking local health reports or having a conversation with your family about safety measures, every step counts. The West Coast surge is a signal, not a siren. But it’s loud enough to make us pay attention.
What’s your take? Are you seeing more masks in your neighborhood, or does it feel like business as usual? The beauty of this moment is that we have tools—data, science, and a bit of common sense—to navigate it. Let’s use them wisely.

As we move forward, the key is balance. We can live our lives while keeping one eye on the horizon. The virus might be making a comeback, but so is our resilience. Let’s keep the conversation going—what steps are you taking to stay safe?
