You wake up with that scratchy, sandpaper feeling in the back of your throat. By noon, your head feels like it’s being squeezed in a vise, and you’re wondering if you should cancel your dinner plans or just power through. You aren't alone. It feels like every third person in the grocery store is stifling a cough or sporting that tell-tale "sick voice." If you’re trying to figure out what colds are going around, the answer is actually a messy cocktail of different viruses that have decided to throw a party in our respiratory systems all at once.
It’s a weird time for germs.
We used to have very predictable "seasons" for things, but since 2020, the timing has been completely out of whack. Honestly, what we call "a cold" is usually one of about 200 different viruses. Right now, we’re seeing a massive overlap of Rhinoviruses, Enteroviruses, and a few "new" variants of old favorites that are making people feel absolutely miserable for weeks at a time.
The Usual Suspects: Rhinovirus and Beyond
When you ask what colds are going around, the "big boss" is almost always the Rhinovirus. It’s responsible for more than half of all common cold cases. But here’s the kicker: it’s not just one thing. There are over 100 strains. This is why you can get "a cold," recover, and then get hit again two weeks later by a different version. It feels like your immune system failed, but really, you just met a different stranger at the door.
Lately, doctors are seeing a lot of Enteroviruses too. These are close cousins to the Rhinovirus but they tend to bring more "body" symptoms. We’re talking about that deep fatigue that makes you want to stare at a wall for three hours. According to the CDC’s surveillance data, these viruses have been circulating at higher-than-normal levels during off-peak months.
Then there’s the "Long Cold."
You’ve probably heard of Long COVID, but researchers at Queen Mary University of London recently published a study in The Lancet’s eClinicalMedicine showing that "Long Colds" are very real. People are reporting coughs, stomach pain, and dizziness that linger for more than four weeks after the initial infection. If you feel like your "cold" is taking forever to leave, it might not be a new infection; it might just be the tail end of a particularly stubborn strain of Adenovirus or Respiratory Syncytial Virus (RSV).
RSV isn't just for kids anymore
We used to think of RSV as a "baby virus." Not anymore. For healthy adults, it usually just looks like a bad cold. You get the runny nose, the decreased appetite, and a cough that sounds like you’ve been smoking for forty years. However, for older adults or those with asthma, it’s becoming a major player in hospitalizations. The data from the National Respiratory and Enteric Virus Surveillance System (NREVSS) shows that RSV peaks can be unpredictable, often hitting earlier in the autumn than they did a decade ago.
Why it feels "worse" this year
Is it just me, or are these colds getting meaner?
Actually, there’s some science behind that feeling. Our "immunological debt"—a term that experts like Dr. Peter Hotez have discussed—suggests that because we spent a few years masked up and distancing, our immune systems didn't get their regular "software updates" from minor germs. Now that we’re back to normal life, every little bug feels like a heavyweight champion.
Plus, we have "coinfections."

It is entirely possible (and unfortunately common right now) to have a Rhinovirus and a mild case of COVID-19 or Flu at the exact same time. This is the "multiplex" of illness. When you have two different viruses fighting for space in your cells, your inflammatory response goes into overdrive. That’s why you feel like you’ve been hit by a truck even if your "test" says you’re negative for the big stuff.
The "Negative Test" Conundrum
Speaking of tests, people are getting frustrated. You feel like death, you take a rapid COVID test, and it’s negative. You take another one 24 hours later. Still negative.
There are two things happening here. First, the viral load for these newer "colds going around" might not peak until day 3 or 4 of symptoms. Second, the rapid antigen tests we have in our medicine cabinets are designed for SARS-CoV-2, not the dozens of other viruses making you sneeze. If you have a fever and a negative COVID test, you likely have a Parainfluenza virus or a Human Metapneumovirus (hMPV).
hMPV is one of those "hidden" viruses. It was only discovered in 2001, but it’s a major cause of upper respiratory infections. It looks exactly like a cold, but it’s notorious for causing a lingering, hacking cough that lasts for weeks.
How to tell what you actually have
It’s hard to self-diagnose, but there are some "vibes" to these viruses that can give you a hint.
If your main symptom is a runny nose and a sore throat but you feel mostly "okay" energy-wise, it’s likely a classic Rhinovirus. If you have a sudden fever, chills, and your muscles ache like you ran a marathon you didn't sign up for, that’s usually Influenza. If you have "pink eye" symptoms along with a cold, you’re likely looking at an Adenovirus—those are particularly hardy and can live on surfaces like doorknobs for a long time.
- Rhinovirus: Sneezing, sore throat, mild stuffiness.
- RSV: Heavy mucus, wheezing, "wet" cough.
- Adenovirus: Fever, sore throat, and sometimes conjunctivitis (pink eye) or stomach issues.
- hMPV: Intense cough, shortness of breath, fatigue.
Honestly, the treatment for almost all of these is the same: stay hydrated and rest. But knowing what’s going around helps you manage your expectations for recovery. A Rhinovirus might clear in 5 days. An Adenovirus or hMPV might hang around for 10 to 14.
The role of "FLiRT" and new variants
We can't talk about what colds are going around without mentioning the elephant in the room. The "FLiRT" variants of COVID-19 (named after specific mutations in the spike protein) have changed the game. For many vaccinated or previously infected people, a COVID infection now presents exactly like a common cold.
The "loss of taste and smell" symptom is mostly gone. Now, it's just a headache and a runny nose. This makes it incredibly easy to spread what you think is a "little cold" when it’s actually a highly contagious variant. If you’re around people who are high-risk, it’s worth doing a PCR test or a molecular test (like Cue or Lucira) which are way more sensitive than the cheap $5 strips.
Real-world prevention that actually works
You’ve heard "wash your hands" a million times. It’s boring advice. But let’s talk about why it matters for the specific bugs moving through communities right now.
Many of these viruses are "enveloped," meaning they have a fatty outer layer that soap easily destroys. Others, like Norovirus (which sometimes hitches a ride with cold symptoms as a "stomach cold"), are non-enveloped and much harder to kill with just hand sanitizer. You actually have to friction-wash them off your skin.
Also, humidity matters.
In the winter, the air is dry. This dries out your nasal membranes. Your mucus is actually a high-tech security system; it traps viruses before they can enter your cells. When your nose is dry, the "security guards" are on strike. Using a saline nasal spray or a humidifier can genuinely lower your chances of catching whatever is going around the office.
What about supplements?
The science on Vitamin C is... meh. It might shorten a cold by half a day if you take it regularly before you get sick, but it won’t do much once you’re already symptomatic. Zinc, however, has better data. Studies from the Cochrane Database of Systematic Reviews suggest that if you take zinc acetate lozenges within 24 hours of the first symptom, you can significantly reduce the duration of the cold. Just don’t use the nasal swabs; they can mess with your sense of smell.
Actionable steps for the "Sick Season"
If you’re currently in the thick of it or trying to avoid the wave of colds going around, here is the practical blueprint.
- Upgrade your testing game. If you feel sick but the rapid test is negative, assume you are contagious anyway. Wait 48 hours and test again.
- Focus on "The Big Three" of recovery. Sleep is the only time your T-cells really go to work. Hydration keeps your mucus thin so you can cough it out. Humidity (60%) keeps your respiratory tract from becoming a playground for viruses.
- Clean the "High-Touch" zones. Most people forget their phone screens and car steering wheels. These are essentially petri dishes. A quick wipe with an alcohol-based cleaner once a day can break the cycle of re-infection in a household.
- Listen to your cough. A "dry" bark is often viral irritation. A "wet" cough that brings up green or yellow gunk—especially if accompanied by a new fever after you started feeling better—could be a secondary bacterial infection like bronchitis. That’s when you call the doctor for real.
- Don't rush back. The "hero culture" of going to work sick is how these outbreaks happen. Most of these viruses are most contagious in the first 3 days. Stay home.
The current landscape of respiratory illness is more complex than it used to be. We are dealing with a "permacold" environment where various viruses are overlapping in ways we haven't seen before. By recognizing the specific symptoms of things like RSV, hMPV, and the new variants, you can better navigate the season without losing your mind—or all your PTO days. Keep your nasal passages hydrated, keep your hands clean, and give your body the actual time it needs to fight back.
