Yes, a stuffy nose is a recognized symptom of COVID-19 and has become one of the most commonly reported signs of infection. The CDC lists “congestion or runny nose” on its official symptom list alongside fever, cough, sore throat, and fatigue. With newer variants, nasal congestion has actually moved up in prominence, reported by roughly 62% of patients infected with Omicron-era strains.
Why Stuffy Nose Became More Common With Newer Variants
COVID hasn’t always looked this way. During the first year of the pandemic, nasal symptoms like congestion and a runny nose were relatively uncommon. The original strain and early variants tended to cause more lower respiratory problems, such as cough, shortness of breath, and pneumonia. A stuffy nose wasn’t considered a hallmark sign.
That shifted significantly with Omicron. Research published in the International Forum of Allergy & Rhinology found that nasal congestion was the single most common symptom reported during an Omicron-era study, ahead of fatigue (55%), fever (54%), and cough (51%). A runny nose followed close behind at about 58%. The virus essentially moved its primary target from the lungs to the upper airways, making it feel much more like a typical cold. This shift also explains why newer COVID infections are harder to distinguish from other respiratory viruses based on symptoms alone.
How COVID Causes Nasal Congestion
The virus enters your body through cells lining the nose and sinuses. These cells are rich in a specific surface protein that acts as a doorway for the virus. Once the virus attaches and enters these cells, your immune system responds with inflammation, swelling the nasal tissues and ramping up mucus production. The glands beneath the nasal lining are especially vulnerable to infection, which can disrupt normal mucus balance and contribute to that plugged-up feeling. This same process in the upper part of the nasal cavity, near your smell receptors, is what can lead to a temporary loss of smell in some people.
COVID vs. Cold vs. Allergies
A stuffy nose alone doesn’t point to any single cause. According to an NIH comparison, nasal congestion is equally common in colds, allergies, and COVID-19. But the surrounding symptoms can help you narrow things down.
- Allergies tend to cause itchy eyes, nose, or ears along with sneezing. They aren’t contagious and often follow a seasonal or environmental pattern. Fatigue and body aches are unusual with allergies.
- A common cold typically brings sneezing, a runny nose, and mild fatigue. It usually doesn’t cause fever, significant body aches, or loss of taste and smell.
- COVID-19 is more likely to include fatigue, body aches, fever, and sore throat alongside congestion. A new loss of taste or smell, while less common with recent variants, still points more strongly toward COVID than a cold or allergies. Sneezing is rare with COVID, which is one useful distinguishing clue.
The overlap is significant enough that you can’t reliably tell the difference by symptoms alone, especially during cold and flu season. Testing is the only way to confirm.
When Congestion Is Your Only Symptom
It’s entirely possible for a stuffy nose to be your first or even your only noticeable COVID symptom, particularly with milder infections. If you’re otherwise healthy and vaccinated, a COVID infection may never progress much beyond upper respiratory discomfort. That said, most people with COVID do develop at least one or two additional symptoms within a day or two, such as a sore throat, fatigue, or mild headache.
If a stuffy nose is all you’re experiencing, the CDC recommends testing to rule COVID in or out. For the most reliable result with an at-home antigen test, the FDA advises testing twice, 48 hours apart. A single negative test can miss an early infection because the virus may not yet be at detectable levels. If your first test is negative but symptoms continue or worsen, test again.
Stuffy Nose in Children With COVID
Kids with COVID tend to present differently than adults. A systematic review of pediatric cases found that nasal symptoms, including congestion and runny nose, appeared in about 11% of children with confirmed infections. Fever (48%) and cough (42%) were far more dominant. So while a stuffy nose can absolutely be part of a child’s COVID illness, it shows up less frequently than in adults and is rarely the leading symptom.
How Long COVID Congestion Typically Lasts
For most people, nasal congestion from COVID clears within one to two weeks, following a similar timeline to congestion from a cold. The stuffiness often peaks in the first few days of illness and gradually improves as other symptoms fade.
In some cases, though, nasal and sinus symptoms can linger. Swelling in the nasal passages during the acute infection can temporarily block the olfactory cleft, the narrow channel where smell receptors sit, contributing to prolonged changes in smell or taste that persist for weeks or months. Persistent congestion lasting beyond 12 weeks would overlap with the timeline for chronic sinusitis, and it’s worth getting evaluated if your symptoms haven’t resolved by that point. Research has found, however, that COVID infection doesn’t appear to make pre-existing chronic sinus conditions worse in the long run.
