  • Coronavirus Pandemic Update 44: Loss of Smell & Conjunctivitis in COVID-19, Is Fever Helpful?


    Coronavirus (COVID-19) Update 44 with Roger Seheult, MD of

    There is new evidence that loss of smell (anosmia) may be an indicator of COVD-19 infection. New reports also suggest that COVID-19 may cause conjunctivitis (pink eye), and be potentially spread through contact with the conjunctiva. Dr. Seheult discusses evidence about how untreated fever may be beneficial for fighting viral illnesses such as coronavirus.

  • Few people experience persistent smell loss | COVID-19 Special


    A study of 2,500 patients, who lost their sense of smell and or taste, showed 40% of them had completely regained it -- half a year later. 2% reported no improvement whatsoever. Scientists believe COVID attacks the cells that help communicate what we're smelling. We can lose our appetite or worse still, the will to live.

  • Heres why some COVID patients lose sense of smell, taste


    Thousands of people who have been infected with COVID-19 have reported symptoms of losing smell and taste. Scientists are figuring out why this happens.

  • How smell training is helping COVID-19 patients recover their olfactory sense


    Loss of smell is a common symptom of COVID-19. Though a majority of patients recover their olfactory sense within weeks, some researchers estimate that 10% suffer long-term smell dysfunction. Los Angeles Times reporter Brittny Mejia looked into why this occurs and what people can do to regain their sense of smell.

  • Loss of smell, taste due to COVID-19 becoming more common among infected patients


    The loss of smell and taste among COVID-19 patients has many in the medical community baffled, and it is not as uncommon as you think.

  • Is Loss of Smell or Taste a Symptom of Coronavirus?


    Dr. Hao “Mimi” Tran recently received a call from one of her dear friends who asked, “Is loss of smell or taste a symptom of coronavirus? Will I get my sense of smell and taste back?” She had recently contracted coronavirus, COVID-19, and was still in quarantine.

    She found out she had the virus 8 days after testing.

    Interestingly, in some cases, sudden loss of smell or taste may be the only symptom of COVID-19. This has been seen worldwide according to doctors in France, Northern Italy, the UK, Germany and South Korea.

  • Long-haul COVID-19 and Smell Loss - Explanation & Next Steps


    In this episode of EUFOREA News, host Dr David Bull as he explores the extraordinary symptom that many people have been suffering from after they've been struck down by COVID-19.

    Dr Bull is joined by Professor Basile Landis, Associate Physician, Head of Rhinology and Olfactory Unit at @Université de Genève (UNIGE) and a world expert on smell functionality.

    Coronavirus has infected nearly a quarter of a million people worldwide and has killed nearly 5 million people around the world.

    However, those who have survived have been plagued with ongoing symptoms (sometimes referred to as long haul Covid). One of the most striking clinical features of Covid infection is loss of smell, which affects nearly 60% of patients during infection and which may persist after recovery from covid.

    Olfactory dysfunction is a common side effect of many post-viral illnesses but there is a huge body of evidence that indicate that taste and smell loss are common symptoms of COVID-19 that may persist long after the initial infection. This effect has a profound impact on quality of life.

    Learn more about this phenomenon and the next steps you can take if you or someone you know is suffering from COVID-19 smell loss in this episode.

  • How to Get Your Smell Back After Covid with Smell Training


    Lost your smell after Covid? Here's how you can use olfactory training or smell training to restore your sense of smell. Most cases of anosmia (lack of smell) return after 2-3 weeks after a viral infection like Covid19. Most people regain their sense of smell and taste within 7 days, but don't lose hope if you've been waiting for 2-3 weeks or more and still can't smell. Smell therapy (like physical therapy for your sense of smell!) has shown to be an effective way to restore your sense of smell, even with long term cases of anosmia.

    Based on the most commonly cited study by Dr. Thomas Hummel, olfactory training uses four unique scents designed to cover different fragrance categories using:

    Lemon for fruity smells:
    Rose for a flower fragrances:
    Cloves for spicy or bitter smells:
    And Eucalyptus for ethereal odors or resinous smells similar to fresh cleaning solutions:

    How to Perform Smell Training:
    Step 1: Find at least 4 familiar fragrances such as Lemon, Rose, Cloves, and Eucalyptus (see above). Place 5-6 drops of oil on a piece of absorbent paper like watercolor paper and place into an amber glass jar:

    Step 2: Twice a day, smell each container for about 10 to 15 seconds, taking just take a couple small sniffs of the fragrance. Try to keep the smell at the top of your nasal cavity instead of taking a giant whiff of the jar.

    Step 3: Track Your Progress
    Keep track of your progress each day by rating how strong you find each smell with each attempt.

  • Why Are People Losing Smell After Recovering From COVID-19?


    70% of people report decreased or loss of smell and/or taste after being infected with COVID-19 and about 10% of them have persistent loss of smell for months after recovering from infection. We are going to talk about what may be causing these changes in smell and taste (neuroinvasion? epithelial damage?), how long they may last, and what may be used to treat the symptoms.

    We are going to use a case study to assist in this discussion on a 65 year old woman with persistent loss of smell and taste for 3 months after she recovered from COVID-19. She had a negative PCR swab, but was positive for SARS-CoV-2 antibodies. They did an extensive workup and found that her symptoms seemed to stem from epithelial damage around the olfactory nerves (nerves that sense smell). This is important as one of the theories of this loss of smell was neuroinvasion, or direct viral invasion of the nerves that can travel to the brain. This doesn't seem to be the case, rather it seems that the epithelial cells around these nerves are being destroyed from invasion of the virus and then that is causing the nerves to be damaged. We will discuss how this works and what this means. We will then go into what treatments have been tried, have been effective, and still need to be studied further. Check out the video for all of these details and more!

    Well, we don’t know exactly, but one of our Members, Peter Brennan, Reader in Physiology from the University of Bristol, tells us that there are two possible explanations:

    Let’s say you have something nice cooking in the oven. As it’s baking, it releases particles that waft into your nasal cavity and attach to olfactory sensory neurons - the cells that detect what we smell and then signal this information to the brain.

    COVID-19 could be killing off these olfactory sensory neurons, keeping the signal of what you’ve just smelled from getting to your brain.

    Another possibility is that inflammation, part of the body’s response to fight off COVID-19, causes swelling in the nose that blocks off the airflow and prevent odour molecules from getting to the olfactory sensory neurons.

    When we talk about how this relates to lack of taste, what we are really referring to is lack of flavour. Our taste buds are still sensing sweetness or saltiness but we process the complex flavours of food by combining these tastes with what we smell. This is why when we have a blocked nose and can’t smell our food, it often tastes bland!

  • Coronavirus: loss of taste or smell added to official symptoms - BBC News


    Loss of taste and smell has been added to the list of official symptoms of coronavirus infection. Previously the list only included a high temperature and a new, continuous cough. The new guidance was set out by the Chief Medical Officers of England, Scotland, Wales and Northern Ireland.

    Some doctors have criticised the government for acting too slowly. They say that loss of taste and smell were known to be symptoms weeks ago and leaving them off the official guidance meant that hundreds of thousands of cases may have been missed, with infection spread as a result.

    The government has also announced that anyone in the UK aged 5 and over with symptoms of the coronavirus can now have a test. Ministers made the pledge despite frequently failing to reach their current target of 100,000 tests a day. Some key workers are still facing long waits to get their results.

  • New Coronavirus Symptom: Loss Of Taste And Smell


    Fever, cough and shortness of breath are the typical symptoms of the coronavirus, but doctors say there is another symptom to keep an eye out for-- a loss of smell. Dr. Mallika Marshall reports.

  • Loss of smell or taste might signal coronavirus infection, doctors say


    Doctors are reporting that people infected with the new coronavirus may lose their sense of smell and perhaps taste.

  • Sudden loss of your sense of smell could mean COVID-19 infection / YTN NEWS


    Professionals are saying if you are unable to smell or taste things, you may have COVID-19.

    Among patients diagnosed with COVID-19, some patients without the usual symptoms of fever and coughing have shown a loss of scent and taste.

    We have Reporter Kim Jin-du reporting.

    Rudy Gobert was the first American professional basketball player to be diagnosed with COVID-19.

    Recently, he posted on his social media that losing your sense of taste and smell are symptoms of COVID-19 and that he hasn't been able to smell anything for the past four days.

    The British Rhinological Society has stated that the loss of scent could be a new symptom of COVID-19.

    A loss of smell naturally leads to the loss of taste.

    The rhinological society stated that 30% of Korea's COVID-19 cases have had issues with their sense of scent.

    If there are no signs of fever or coughing, the loss of smell and taste could be a helpful symptom in diagnosing cases of the virus.

    The results of a study by a virologist at the University of Bonn show that out of 100 people, two out of three diagnosed cases had seen a decline in their senses of scent and taste over the past few days.

    The Association of Physicians has stated a loss of sense of scent may occur if you are infected with COVID-19.

    [Jin Beom-sik / Doctor, Infectious Disease Department : Rhinovirus and cold viruses are the most common cause of this, but it is also a symptom of COVID-19. Even doctors who are treating this now are seeing these cases in their patients.]

    The loss of sense of scent could be a new indicator for COVID-19.

    But being able to differentiate it from allergies, rhinitis, sinus infections, or a regular cold is the key to utilizing this symptom.

    This has been Kim Jin-du of YTN.

  • Why Do Coronavirus Patients Lose Their Sense of Taste and Smell?


    Dr. Robert Kern, chair of the Otolaryngology department at Northwestern University, explains why coronavirus infections may result in the loss of taste and smell, a phenomenon known as anosmia. #Coronavirus #Covid19 #CoronavirusSymptoms #CoronavirusTips

    The coronavirus is capable of attacking key cells in the nose, which may explain the unusual finding that some Covid-19 sufferers lose their ability to smell and taste, Harvard Medical School researchers found.

    Their study of human and mice genomic data found certain cells at the back of the nose harbor the distinctly shaped proteins that the coronavirus targets to invade the body. Infection of these cells could directly or indirectly lead to an altered sense of smell, they said in a paper published Saturday.

    Doctors around the world are reporting anecdotal Covid-19 cases in which patients have experienced an abrupt and unexplained total or partial loss of smell and taste. The conditions, known medically as anosmia and dysgeusia, respectively, are “significant symptoms” associated with the pandemic, the American Academy of Otolaryngology, or head and neck surgery, said on March 22.

    The group, based in Alexandria, Virginia, proposes that these symptoms be added to the list of screening tools for possible Covid-19 infection. People experiencing the symptoms in the absence of other known causes should consider self-isolation and get tested, the group said.

    Inflammation in the nasal cavity triggered by the pandemic-causing infection may hinder the sense of smell, David Brann and Sandeep Robert Datta of the Harvard Medical School’s neurobiology department said. But it’s also possible the virus infects and damages cells in the nasal epithelium required for normal olfactory function.

    Uncovering the cause of the sensory loss has important implications to support diagnosis and determine the effects of the disease, the researchers said.

    “Furthermore, patients with persistent olfactory dysfunction are at risk of nutritional deficits, of injury due to the inability to smell ‘danger’ odors like smoke, gas and spoiled foods, and of developing psychiatric disorders, particularly depression,” they said.

  • Can’t smell suddenly? You could have coronavirus


    A sudden loss of smell and taste could be a sign of mild coronavirus disease. Covid-19 symptoms include fever, dry cough, tiredness, shortness of breath or difficulty breathing. Those with a sudden loss of smell must home-quarantine and get tested for coronavirus disease. Very few conditions lead to sudden amnosia, or the loss of smell and taste. It should be treated as a sign of coronavirus disease, especially by people who risk exposure at the frontlines, such as health workers. People with a sudden loss of smell are 10 times more likely to have Covid-19 than any other infection, according to a study by the University of California in San Diego. The effect was temporary and patients recovered taste and smell within a few weeks of infection.

  • Loss of smell or taste added to NHS coronavirus symptoms list | ITV News


    A loss or changed sense of taste or smell are to be added to the NHS coronavirus symptoms list, weeks after experts first raised concerns that Covid-19 cases are being missed.

    Anyone suffering loss of taste or smell, or a noticeable change, should now self-isolate for seven days to reduce the risk of spreading the infection, England’s deputy chief medical officer, Professor Jonathan Van-Tam said.

    If the symptomatic person lives with others, they should stay at home for seven days, while all other household members should stay home for 14 days even if they do not have symptoms.

    The move means a change or loss of smell or taste will now be listed alongside a fever and a cough as the main symptoms of Covid-19.

    Prof Van-Tam told reporters it would mean 93% of cases where people have symptoms are now picked up, a rise from 91% previously.
