COVID-19 is milder than it was in 2020, but it still isn’t equivalent to a common cold. It hospitalizes and kills people at rates that place it closer to seasonal flu, and it hits certain age groups, particularly adults over 75 and infants under 6 months, considerably harder than a typical cold virus ever would.
The confusion is understandable. Most people who catch COVID today experience a few days of sore throat, congestion, and fatigue, then recover. That feels like a cold. But “feels like a cold for most people” and “is a cold” are two different statements, and the gap between them matters.
How Severe Is COVID in 2025?
COVID’s severity has dropped dramatically since the early pandemic waves, thanks to widespread immunity from both vaccination and prior infection. But it hasn’t dropped to the level of a cold. CDC hospitalization data from the 2024-2025 season shows COVID still puts people in the hospital at meaningful rates: 653 per 100,000 for adults 75 and older, 195 per 100,000 for adults 65 to 74, and 223 per 100,000 for infants under 6 months. For comparison, the common cold virtually never causes hospitalization in healthy adults.
A 2025 study of U.S. veterans published in JAMA Network Open compared COVID and flu side by side during the same time period. In February 2025, COVID caused roughly 1.12 deaths per 100,000 people per month, while seasonal flu caused about 2.52 deaths per 100,000. That puts COVID and flu in the same ballpark, with flu actually running higher in that particular month. Both are far more dangerous than the common cold, which is almost never fatal outside of extremely fragile populations.
So COVID has moved from “significantly worse than the flu” to “roughly comparable to the flu, depending on the season.” That’s real progress. But comparable to the flu is still not comparable to a cold.
What Makes COVID Different From a Cold
The common cold is caused by a rotating cast of viruses, most often rhinoviruses. These viruses primarily infect the upper airways: your nose, throat, and sinuses. They rarely spread deeper into the body. That’s why colds are annoying but almost never dangerous.
SARS-CoV-2 can infect a wider range of tissues. The virus enters cells through a receptor found not just in the lungs but in blood vessels, the heart, the gut, and the brain. This is why COVID can occasionally cause complications that a cold simply doesn’t: blood clots, heart inflammation, neurological symptoms like prolonged loss of smell, and pneumonia. These complications are uncommon in vaccinated, otherwise healthy people, but they still occur at rates that set COVID apart from rhinovirus infections.
COVID is also more contagious. The Omicron variant, which gave rise to the subvariants circulating today, had an average basic reproduction number (R0) of about 1.56, meaning each infected person spread it to roughly one and a half others on average. In some countries the R0 exceeded 1.9. The common cold typically has an R0 closer to 1.0 to 1.2. Higher transmissibility means more people get infected in a shorter window, which translates to more hospitalizations and deaths even if the per-case severity is low.
Long-Term Symptoms After Infection
One of the biggest concerns that separates COVID from a cold is what happens after the acute illness resolves. Long COVID, characterized by fatigue, brain fog, shortness of breath, and other symptoms lasting weeks to months, drew enormous attention early in the pandemic. But newer research is providing a more nuanced picture.
A large retrospective study of U.S. adults published in PLoS Medicine compared post-acute symptoms between COVID and flu patients. Within the first 31 to 90 days after infection, COVID cases had only modestly higher rates of lingering health issues than flu cases. By 91 to 180 days, the difference was even smaller. However, COVID patients were about 24 to 31 percent more likely to need hospitalization for severe post-acute conditions during that same window. The researchers noted that their findings “challenge assumptions about the uniqueness of post-acute COVID-19 morbidity” while also suggesting that flu’s long-term burden may be underrecognized.
In other words, lingering symptoms after respiratory infections aren’t unique to COVID, but COVID still produces more serious post-viral complications than flu does. And both produce far more lasting effects than a common cold, which almost never leads to weeks of fatigue or brain fog.
Who’s Still at Serious Risk
For a healthy, vaccinated 35-year-old, COVID in 2025 probably will feel like a bad cold or a mild flu. The hospitalization rate for adults 18 to 49 is about 27 per 100,000, which is low. This is the experience that drives the “it’s just a cold” perception, and it’s valid as a description of individual risk for that group.
The picture looks different at the extremes of age. Adults 75 and older are hospitalized at a rate of 653 per 100,000, roughly 24 times the rate of younger adults. Infants under 6 months are hospitalized at 223 per 100,000. Adults 50 to 64 fall in the middle at 74 per 100,000. People with chronic conditions like diabetes, heart disease, obesity, and immune suppression also face elevated risk regardless of age.
This age gradient is steeper than what you see with the common cold, where hospitalization is rare across all age groups. It’s more similar to the pattern seen with flu, where the very old and very young bear most of the burden.
Why the “Just a Cold” Framing Matters
Calling COVID “just a cold” isn’t only a scientific question. It shapes behavior. If people believe COVID is equivalent to a cold, they’re less likely to stay up to date on vaccinations, less likely to test when symptomatic, and less likely to take precautions around vulnerable family members. For a young, healthy person making decisions only about their own body, that shift in behavior may not matter much. For a grandparent, a newborn, or someone on immunosuppressive medication, it can.
The most accurate way to think about COVID in 2025 is that it has become an endemic respiratory virus roughly on par with seasonal flu for most people, still capable of serious harm in high-risk groups, and meaningfully more dangerous than a common cold. It’s not the emergency it was in 2020. It’s also not something your immune system shrugs off the way it handles a rhinovirus.
