18th May 2020 : UK Accepts and Recognises Smell Loss as an Official Symptom of Covid-19
A joint statement from the four Chief Medical Officers in the UK said:
‘From today, all individuals should self-isolate if they develop a new continuous cough or fever or anosmia. ‘Anosmia is the loss or a change in your normal sense of smell. It can also affect your sense of taste as the two are closely linked. We have been closely monitoring the emerging data and evidence on COVID-19 and after thorough consideration, we are now confident enough to recommend this new measure. The individual’s household should also self-isolate for 14 days as per the current guidelines and the individual should stay at home for seven days, or longer if they still have symptoms other than cough or loss of sense of smell or taste.’

29th March 2020: New research suggests a possible cause for anosmia associated with COVID-19
Dr Darren Logan, Head of Research at Waltham Science, and the Datta Lab at Harvard Medical School have discovered a possible cause for anosmia that is being reported by some people affected by COVID-19. Dr Logan has provided a summary of the research for Fifth Sense:
As more people are being diagnosed with COVID-19, doctors have begun to report that anosmia is a relatively frequent symptom. As the viral pandemic is still ongoing, it is not yet clear quite how common, or even whether the smell loss is temporary or permanent in those infected with the Cov-2 coronavirus. After this clinical feature was first reported, a group of scientists looked closely at the molecular machinery in the noses of healthy people. They were seeking the particular proteins made by our bodies that the virus needs to attach to, for it to be able to infect our cells. They were surprised to find that the nerves in the nose, the critical cells that actually transmit the sense of smell, do not make the proteins needed for viral entry.
So how could the coronavirus cause anosmia? They next looked at all the other types of cells present in our noses, and found a few types that can be infected. Among these were so-called “sustentacular cells”, which are neighbours of sensory nerves in the nose and are there to provide support, nourishment and protection. The scientists concluded that the anosmia associated with COVID-19 is probably due to these cells in the nose being infected. And when the body launches an immune response to fight off the infection, the nerves lose their support and stop working. This preliminary research was conducted and shared really quickly due to the COVID-19 crisis, so it will take some time before other scientists can review and confirm whether the conclusions are correct.

Covid-19 and smell loss update Friday 27th March 2020:
Research and information continues to be available if you are newly experiencing smell loss and have been (or suspect you have been) infected with Covid-19.

This article was updated on Thursday 26th March 2020 to include advice produced by ENT UK for patients with new onset smell loss (anosmia) during the Covid-19 pandemic.
“ENT surgeons across the globe have shared reports that they have seen a peak in patients reporting anosmia in the last month. We believe this is related to COVID-19 infection. At present, many affected
patients do not have other symptoms, or only mild disease, and therefore do not meet the criteria for testing. While loss of smell may be caused by other viruses, we think that it is reasonable to assume
that COVID-19 is the cause until tests prove negative. We therefore advise that patients follow
current guidelines for self-isolating if they develop new onset anosmia.
This will also apply to cohabiting friends or family.
Please do not call NHS111 or your GP unless you have respiratory or other problems that need
medical attention. Equally, DO NOT visit the GP surgery or A&E for loss of sense of smell.
With regards to treating the anosmia, the good news is that colleagues in Italy report encouraging
rates of recovery, with many patients reporting return of sense of smell within 7 – 14 days. This
seems to be the experience of patients in the UK.”

Guidance From Fifth Sense Medical Director, Prof. Carl Philpott, Saturday 21st March 2020
Following concerns being raised on a number of mediums this week with regard to smell loss following infection of confirmed and non-confirmed COVID-19 (or similar but undiagnosed symptoms), we thought it would be helpful to provide the following guidance and support.
The 2nd most common cause of smell loss – anosmia – is Post Viral Olfactory Loss (PVOL). Some studies suggest that approximately 12% of people with acquired anosmia have it as a result of a flu/cold like virus and we know COVID-19/Corona Virus is in this category.
Smell loss may only be temporary but it is distressing for those experiencing it; at the current time we don’t know whether the effects of Covid-19 will be transient or not.
Fifth Sense has advice and guidance on how you can alleviate some of the symptoms and apply some self-help interventions www.fifthsense.org.uk If you are experiencing unexpected smell loss for any reason, we would advocate smell training to help you to keep your olfactory system exposed to smells – please visit www.fifthsense.org.uk/smell-training/
If you have any concerns or wish to seek support please contact us at: info@fifthsense.org.uk and we will do what we can to help.
We have seen social media comments regarding the use of steroids, our Medical Director Prof. Carl Philpott, ENT consultant at the Norfolk Smell & Taste Clinic, advises against the use of oral steroids in COVID-19 or suspected infection but nasal steroids are safe to use.
Please follow all COVID-19 Public Health advice and guidance and as with all cold and flu virus’s stay hydrated and rest to support recovery. Take care, stay safe and look after yourself and each other

Statement from ENT UK and BRS – Friday 20th March 2020
Fifth Sense were sent the following statement by Prof Claire Hopkins, President of the British Rhinological Society, and Prof Nirmal Kumar, President of ENT UK on Friday 20th March, which has also been sent to Public Health England.
There is new evidence for the loss of smell as a symptom of COVID-19 infection. We are circulating the following intelligence to Public Health England with regards to anosmia….details can be read below:
Post-viral anosmia is one of the leading causes of loss of sense of smell in adults…… Viruses that give rise to the common cold are well known to cause post-infectious loss, and over 200 different viruses are known to cause upper respiratory tract infections……. It is therefore perhaps no surprise that the novel COVID-19 virus would also cause anosmia in infected patients.
There is already good evidence from South Korea, China and Italy that significant numbers of patients with proven COVID-19 infection have developed anosmia/hyposmia. In Germany it is reported that more than 2 in 3 confirmed cases have anosmia. In South Korea, where testing has been more widespread, 30% of patients testing positive have had anosmia as their major presenting symptom in otherwise mild cases.
In addition, there have been a rapidly growing number of reports of a significant increase in the number of patients presenting with anosmia in the absence of other symptoms – this has been widely shared on medical discussion boards by surgeons from all regions managing a high incidence of cases. Iran has reported a sudden increase in cases of isolated anosmia, and many colleagues from the US, France and Northern Italy have the same experience. I have personally seen four patients this week, all under 40, and otherwise asymptomatic except for the recent onset of anosmia – I usually see roughly no more than one a month. I think these patients may be some of the hitherto hidden carriers that have facilitated the rapid spread of COVID-19. Unfortunately, these patients do not meet current criteria for testing or self-isolation.
While there is a chance the apparent increase in incidence could merely reflect the attention COVID-19 has attracted in the media, and that such cases may be caused by typical rhinovirus and coronavirus strains, it could potentially be used as a screening tool to help identify otherwise asymptomatic patients, who could then be better instructed on self-isolation.
Given the potential for COVID-19 to present with anosmia, and the reports that corticosteroid use may increase the severity of infection, we would advise against use of oral steroids in the treatment of new onset anosmia during the pandemic, particularly if it is unrelated to head trauma or nasal pathology (such as nasal polyps).
Yours sincerely,
Prof Claire Hopkins, Prof Nirmal Kumar
