It’s 2024, and honestly, we all just want to move on. But then you hear a neighbor coughing or see a headline about a "summer surge," and the old anxiety creeps back in. Is it happening again?
Basically, the answer is a bit more complicated than a simple "yes" or "no." COVID-19 isn't "coming back" in the sense that it ever actually left. It’s just morphing into a different kind of beast—one that doesn't follow the rules of a typical winter flu.
Why the is covid coming back in 2024 question is everywhere right now
Most of us expected COVID to settle into a neat little winter schedule. We thought it would show up with the snow, peak in January, and vanish by spring. But 2024 proved that’s just not how this virus operates.
Instead of a single "comeback," we’ve seen a series of ripples. In the summer of 2024, the CDC tracked a significant uptick in cases across nearly 40 states. You probably noticed it too. People were testing positive in July while on vacation, which felt weird and out of place. This happens because of two things: our immunity from previous shots or infections starts to fade, and the virus keeps changing its "disguise" to sneak past our defenses.
The stars of the show this year were the FLiRT variants (technical names like KP.2 and KP.3). They are descendants of the Omicron JN.1 strain that dominated last winter. These variants aren't necessarily making people "sicker" in a life-threatening way for most, but they are incredibly good at spreading. They’ve picked up specific mutations that let them latch onto our cells more easily, even if we’ve been vaccinated before.
What the numbers actually say
If you look at the hard data from the CDC’s Respiratory Disease Season Outlook, the picture is actually somewhat reassuring, despite the constant presence of the virus.
- Hospitalizations: They are way lower than they were in 2020 or 2021. In fact, cumulative hospitalization rates for the 2023-2024 season were among the lowest since the pandemic started.
- Death Rates: While every loss is tragic, the mortality rate has stayed consistently low. By mid-2024, many of the deaths associated with the virus were among the very elderly (75+) or those with serious underlying conditions who hadn't received the latest vaccine formula.
- Wastewater: This is the "secret" metric scientists use now. Because people aren't reporting home tests to the government, experts look at sewage data. In 2024, wastewater levels showed that the virus was circulating at high levels during the summer, even if people weren't ending up in the ER as much.
The 2024-2025 Winter Outlook
So, if it surged in the summer, what happens when we all head back indoors for the holidays?
Public health experts like those at Johns Hopkins and the CDC are bracing for a "later" peak this time around. Usually, we see a massive spike right after New Year's Day. But the 2024 data suggests the winter wave might start later and last longer.
The big concern isn't just COVID. It’s the "tripledemic" effect—the overlapping of COVID, the Flu, and RSV. When all three peak at the same time, hospitals get crowded. However, the 2024-2025 forecast suggests there's an 80% chance that the combined burden will be similar to or even lower than last year. We're getting better at managing this.
The new vaccine reality
In August 2024, the FDA gave the green light to updated boosters from Pfizer, Moderna, and Novavax. These aren't just "more of the same." They were specifically "re-tuned" to target the JN.1 lineage and its FLiRT offshoots.
If you're wondering if they work: preliminary data from late 2024 showed the new shots were about 56-76% effective at keeping people out of the urgent care or emergency room. That’s a massive win. But here’s the kicker—fewer than half of Americans are actually getting them. This "vaccine fatigue" is a huge reason why the virus keeps finding room to run.
Long COVID is the silent part of the story
While the "is it coming back" conversation usually focuses on fever and cough, the real 2024 story is about what happens after the infection.
The CDC estimates that about 6% of U.S. adults are currently dealing with Long COVID. That’s millions of people. Research from the RECOVER initiative in 2024 and 2025 has started to pinpoint who is most at risk:
- Women are more likely to report persistent symptoms.
- Adolescents (12-17) are showing higher rates of heart and stomach issues post-infection than we previously thought.
- The unvaccinated still face a higher risk of developing long-term brain fog and fatigue compared to those who stayed up to date on shots.
New studies out of Stanford and other major centers are looking at "olfactory retraining" for people who lost their sense of smell and various blood-thinning therapies for those with "microclots." We are finally moving from "what is this?" to "how do we fix this?"
How to handle the rest of 2024
We aren't going back to lockdowns. That ship has sailed. But being smart about the "new normal" is how you avoid spending your PTO in bed.
Kinda basic, right? But here is what actually works in the current environment.
First, stop relying on a single negative home test. The newer variants sometimes take 2 or 3 days of symptoms before they show up on a rapid test. If you feel like garbage but the test says negative, wait 48 hours and test again. You’re likely still contagious.
Second, think about the "layers." If you're going to a crowded indoor concert in the middle of a surge, maybe that's the time to mask up. If you're just at the grocery store for five minutes, the risk is lower. It’s about being an actuary for your own health.
Actionable steps for right now
- Check the wastewater: Use the CDC’s COVID Data Tracker to see if levels are rising in your specific county before planning big events.
- Update your kit: Most of those tests in your cabinet from 2022 are expired. Check the "extended expiration dates" on the FDA website before you trust them.
- Get the 2024-2025 formula: If it’s been more than six months since your last shot or infection, your "neutralizing antibodies" are likely very low. The new shot is designed for the variants actually circulating right now.
- Ventilate: If you’re hosting people, a simple HEPA air purifier or just cracking a window makes a massive difference.
The bottom line? COVID isn't "coming back" because it never left the building. It’s just part of the background noise of modern life now. We have better tools, better data, and much more collective immunity than we did four years ago. Staying informed without panicking is the goal.
