A loss of taste and smell is a common symptom of COVID-19 infection. In the recovery phase of COVID-19, a patient normally regains their senses back. However, some people experience a change to their sense of smell about three to four months following infection.
With COVID-19, smell loss one of the first signs of infection. “Smell loss is actually an early sign of COVID-19 and usually occurs for those who have a mild form of the virus,” says Tajudeen. “Patients with smell loss are normally at home recovering and not admitted into the hospital or on a ventilator.”
Overall, the study results suggested that though it might take time, up to three years in most cases, COVID-19 patients recover from olfactory dysfunction. Based on observed high OD recovery rates, the researchers reassured patients with SARS-COV-2 infection of a good prognosis.

You may find that foods smell or taste differently after having coronavirus. Food may taste bland, salty, sweet or metallic. These changes don't usually last long, but they can affect your appetite and how much you eat.
When you're congested, it can interfere with the ability to detect scents properly. This can result in a reduced sense of smell, which in turn, affects our sense of taste. Loss of taste is a common symptom experienced by people who are suffering from nasal congestion.
Illness or Infection
Anything that irritates and inflames the inner lining of your nose and makes it feel stuffy, runny, itchy, or drippy can affect your senses of smell and taste. This includes the common cold, sinus infections, allergies, sneezing, congestion, the flu, and COVID-19.
Recently, the Norwegian Institute of Public Health reported the demographics of 117 cases infected with Omicron variant (15). Strikingly, loss of smell and taste was reported in 12% (median duration 2 days) and 23% (median duration 2.5 days), respectively (15).
People with moderate or severe COVID-19 should isolate through at least day 10. Those with severe COVID-19 may remain infectious beyond 10 days and may need to extend isolation for up to 20 days.
If I Have COVID-19, How Long Am I Contagious? According to the CDC, if you have mild to moderate COVID-19, you may be contagious for 10 days from the first day you noticed symptoms. If you were severely affected or critically ill from COVID-19, you may stay infectious for up to 20 days from the start of your symptoms.
However, some people experience a change to their sense of smell about three to four months following infection. People report certain things—like food or body odor—smelling like garbage, rotten eggs, or chemicals.
The research team reported that about 60 percent of surveyed participants infected with COVID experienced a loss of smell and about 58 percent experienced loss of taste. Additionally, not all the patients experienced a full recovery of their senses once they recovered from their infection.
“While the risk of smell loss is far less prevalent than the initial waves of COVID-19, we are still seeing patients who have either completely lost or have a distorted sense of smell, which can take a significant toll on their quality of life.
Repeat negative tests following FDA recommendations. After a positive test result, you may continue to test positive for some time. Some tests, especially PCR tests, may continue to show a positive result for up to 90 days.
WEDNESDAY, June 7, 2023 (HealthDay News) -- One of the signature symptoms of COVID-19 infection in the early months of the pandemic was a loss of the sense of smell. Now, new research finds that is no longer the case, thanks to the new variants that have been circulating more recently.
Our sense of smell in responsible for about 80% of what we taste. Without our sense of smell, our sense of taste is limited to only five distinct sensations: sweet, salty, sour, bitter and the newly discovered “umami” or savory sensation.
Infectiousness usually begins to decrease after day 5, but this doesn't mean you can't spread the virus beginning on day 6. This is why it is SO important to wear a mask through day 10. Everyone's immune response is different, and we can spread the virus for different amounts of time.
Although many people will no longer be infectious to others after 5 days, some people may be infectious to other people for up to 10 days from the start of their infection. If you have a high temperature or still feel unwell after the 5 days, continue to try to stay at home.
Even if mild symptoms remain, you are likely not contagious after 10 days. However, if you have a weakened immune system or severe illness (requiring hospitalization, intensive care or even intubation), you can be contagious for up to three weeks or more.
Experiencing hyposmia or anosmia over a long period of time may indicate chronic sinus infection with or without nasal polyps. It may be due to an obstruction in the nose, such as a deviated septum, tissue swelling or, rarely, tumors of the nasal cavity.
Smell strong-smelling odours (like the ones you briefly eliminated), such as ground coffee, spices, mint, and eucalyptus. The molecules in essential oils taken from plants can also be used for olfactory training.
Anosmia is the partial or full loss of smell. Anosmia can be a temporary or permanent condition. You can partially or completely lose your sense of smell when the mucus membranes in your nose are irritated or obstructed such as when you have a severe cold or a sinus infection, for example.
The other most common cause of smell loss is that due to an ongoing process in the nose and/or sinuses, specifically rhinitis (inflammation in the nose), nasal polyps and/or sinusitis. The history usually is that of gradual loss of smell ability proceeding to total loss.
