Yes, loss of taste is still a recognized COVID-19 symptom, but it is far less common now than it was in the early years of the pandemic. When it does happen, it usually appears alongside other symptoms like congestion, sore throat, or cough, rather than on its own. The virus has changed, and so has the way it affects the senses.
Is Loss Of Taste Still A Covid Symptom Today?
Loss of taste remains on the list of COVID-19 symptoms tracked by public health agencies. What has changed is how often it shows up.
During the early waves of the pandemic, losing taste or smell was one of the clearest signals of infection. Studies from that period found it was common, sometimes affecting a majority of people who tested positive. That pattern has faded.
Researchers who track symptom data have noted a steady drop in reports of taste and smell changes since the original virus strain gave way to later variants. The reasons are not fully settled. It likely comes down to a mix of factors: the virus itself evolved, and most people now carry some immune protection from prior infection, vaccination, or both. That protection does not stop infection, but it appears to blunt some of the stranger symptoms.
So the short answer is yes, it can still happen. But it is no longer the hallmark symptom it once was, and it is rarely the only sign.
How Does COVID-19 Affect Taste?
COVID-19 does not usually attack taste buds directly. The disruption happens further upstream.
Taste and smell are tightly linked. Much of what you think of as flavor actually comes from your nose. When you chew food, aroma molecules travel up the back of your throat to receptors in the nasal cavity. This is called retronasal smell, and it carries most of the nuance in what you taste.
When the virus inflames the lining of the nose and throat, that pathway gets blocked or scrambled. The result feels like lost taste, but the taste buds themselves are often working fine. This is one reason people with COVID-19 sometimes report that they can still detect sweet, salty, or sour flavors while everything else tastes flat or wrong.
There is a second mechanism worth knowing about. The virus can affect support cells around the olfactory neurons — the nerve cells that carry smell signals to the brain. It is not generally thought to destroy those neurons outright. Instead, it disrupts the environment they need to function. That is why many people recover their sense of smell and taste over time.
Some researchers have looked at whether the virus affects the taste buds or the cranial nerves that carry taste signals directly. The evidence here is less clear. Most findings point to smell disruption as the main driver, with taste changes mostly being a downstream effect.
How Common Is Loss Of Taste With Current Variants?
Loss of taste is now uncommon compared to the pandemic’s early days. Estimates vary widely depending on the study, the variant, and how symptoms were reported.
Data collected by symptom-tracking groups and public health surveillance shows a clear downward trend. In the first year of the pandemic, taste and smell changes were reported by a large share of infected people. In later waves, that share dropped substantially. Some studies of Omicron-era infections found these symptoms in a small minority of cases.
It is difficult to put an exact number on it. Different studies define “loss of taste” differently. Some rely on self-report. Some test smell and taste formally. Some count only complete loss, while others include partial or distorted taste. These differences make direct comparisons tricky.
What is consistent across most sources is the direction: less common now than before. If you lose your taste today, COVID-19 is one possible cause, but it is no longer the first thing a doctor would suspect.
What Else Causes Loss Of Taste?
Many conditions can dull or distort taste, and most have nothing to do with COVID-19.
The most common cause is a blocked or inflamed nose. A ordinary cold, a sinus infection, or seasonal allergies can all interfere with the smell pathway and make food taste bland. This is by far the most frequent reason people notice their taste has faded.
Other causes include:
- Other viral infections, including influenza and common cold viruses
- Sinus infections and nasal polyps
- Allergies and chronic nasal congestion
- Medications, including some antibiotics, blood pressure drugs, and antidepressants
- Nutritional deficiencies, such as low zinc or vitamin B12
- Head injury that damages nerves involved in smell or taste
- Neurological conditions, including Parkinson’s disease and Alzheimer’s disease
- Smoking, which can dull taste and smell over time
- Dry mouth from medications, aging, or certain health conditions
- Acid reflux, which can irritate the throat and affect taste
Age matters too. Taste and smell naturally decline with age, often starting in the 60s. A gradual fading over months or years is more likely to reflect aging or a chronic condition than an infection.
Timing helps narrow things down. A sudden loss that appears over a day or two, especially with other symptoms, points toward an infection. A slow decline over months points elsewhere.
How Long Does Loss Of Taste Last After COVID-19?
For most people, taste returns within days to a few weeks. Recovery tends to follow the same timeline as other cold-like symptoms.
A smaller number of people take longer. Some report taste and smell changes lasting weeks or months after other symptoms clear. This is sometimes called post-COVID smell and taste dysfunction. It is more likely with the original virus strains than with later ones, though it can still happen.
A very small group has persistent changes lasting a year or more. Research on this is ongoing, and estimates of how often it happens vary. The evidence suggests it is uncommon, but it is real and can affect quality of life.
If taste changes last more than a few weeks after a respiratory infection, it is worth mentioning to a doctor. Not because it is usually dangerous, but because other causes may need to be ruled out.
When Should You See A Doctor?
Most short-term taste changes are not a medical emergency. But some situations call for a professional evaluation.
See a doctor if:
- Loss of taste comes on suddenly without any cold or flu symptoms
- It lasts more than a few weeks
- It happens alongside weakness, numbness, or trouble speaking
- You also notice a loss of smell that does not improve
- You have trouble eating or drinking because food tastes wrong or unpleasant
- You have other unexplained symptoms, such as weight loss or persistent fatigue
Sudden loss of smell or taste without a clear cause can sometimes be an early sign of a neurological condition. This is rare, but it is one reason doctors take persistent changes seriously.
For most people with a recent respiratory infection, watchful waiting is reasonable. Taste usually comes back on its own.
Can You Get Your Taste Back Faster?
There is no proven treatment that reliably speeds up taste recovery after COVID-19.
Some clinicians recommend smell training, which involves sniffing a set of distinct scents — such as lemon, rose, clove, and eucalyptus — twice a day for several weeks. The idea is to stimulate the olfactory system and encourage it to rewire. Some studies suggest it may help, but results are mixed and the evidence is not strong enough to call it a confirmed treatment.
Steroid nasal sprays are sometimes prescribed for smell loss. The evidence for their benefit in post-viral smell loss is limited and inconsistent. They are not a guaranteed fix.
Zinc and vitamin B12 supplements are sometimes suggested, but only make sense if you are actually deficient. Taking them when you are not deficient has not been shown to restore taste. High-dose zinc can cause side effects, including nausea and a metallic taste, and can interfere with copper absorption.
What does help is patience and safety. If food tastes off or you cannot smell well, you may not notice spoiled food or a gas leak. Check smoke detectors and be careful with leftovers.
If you have a medical condition or take medications, talk to your doctor before adding any supplement.
Frequently Asked Questions
Is loss of taste still a common COVID symptom?
It is still recognized as a symptom, but it is much less common now than in the early pandemic. Most people with current variants report sore throat, cough, congestion, or fever instead.
How long does COVID loss of taste usually last?
For most people, taste returns within days to a few weeks. A smaller number report changes lasting months, and a very small group has persistent symptoms beyond a year.
Can you lose taste without losing smell with COVID?
It is possible, but taste and smell are closely linked, so they often change together. When taste is affected alone, it is more often due to a blocked nose or another cause.
What causes loss of taste besides COVID?
Common causes include colds, sinus infections, allergies, medications, nutritional deficiencies, and aging. A blocked nose is the most frequent reason taste fades.
