‘Long Covid’ victims are being haunted by ‘unbearable’ smells

Fish and burning toast are among the ‘unbearable’ odours in place of normal smells haunting Long Covid patients as more unusual symptoms of the virus emerge. 

Professor Nirmal Kumar, 55, said the ‘very strange and very unique’ long-term symptom is known as parosmia. 

The symptom is the inability of the brain to properly identify an odour’s ‘natural’ smell and seems to be affecting young people and healthcare workers in particular.

The Ear Nose and Throat surgeon was among the first medics to identify anosmia, loss of smell, as a coronavirus indicator in March, and urged Public Health England to add it to the symptom list months before it became official guidance. 

Professor Kumar noticed that some patients he was treating and studying were recovering from long-term anosmia, something he said has affected thousands of people across the UK, only to experience parosmia.  

The president of ENT UK said he saw two patients suffering with parosmia this morning. 

He said: ‘Both are healthcare workers, and we think there is increased incidence in young people and also in healthcare workers because of exposure to the virus in hospitals.

‘For some people, it is really upsetting them. We are calling it neurotropic virus,’ he added.

‘What this means is the virus is affecting the nerves in the roof of the nose – it’s like a shock to your nervous system, and the nerves aren’t functioning.’

Daniel Saveski, a 24-year-old banker living in London, said he lost his sense of taste and smell for two weeks after contracting coronavirus in March and has been suffering with parosmia since.

What is anosmia? 

Anosmia is the medical name for a condition in which someone suffers a complete or partial loss of their sense of smell and/or taste.

The most common single cause of the condition – temporary or permanent – is illnesses which affect the nose or sinuses, such as polyps which grow in the airways, fractured bones or cartilage, hay fever or tumours.

It is different to hyposmia, which is a decreased sensitivity to some or all smells. 

Around 3.5million people in the UK are affected by the condition, along with nearly 10million in the US. It is surprisingly common and affects between three and five per cent of people.

Head injuries and nervous system diseases like Parkinson’s or Alzheimer’s may also contribute to the condition by damaging nerves in the nose which are responsible for detecting smells. 

He added: ‘It’s lessened my enjoyment of food, and it’s a bit depressing not being able to smell certain foods.’

Lynn Corbett, an administrator for an estate agent, said she was ‘shocked’ to wake up on her 52nd birthday in March with ‘absolutely no smell or taste’.

Ms Corbett, from Selsey in Sussex, said: ‘From March right through to around the end of May I couldn’t taste a thing – I honestly think I could have bitten into a raw onion such was my loss of taste.’

She said her sense of smell began to return in June, but ‘nothing smelled like it should’.

‘Most things smelled disgusting, this sickly sweet smell which is hard to describe as I’ve never come across it before,’ she said.

She added that despite being a ‘coffee addict’ before March, the drink now smells ‘unbearable’, as do beer and petrol.

Ms Corbett said: ‘I’m not sure if things will ever return to the way they were.

‘I’m OK with it, I just think myself lucky that if I did have coronavirus, which it looks like I did, then I haven’t been seriously ill, hospitalised or died from it like so many others.’

Charity AbScent, which supports people with smell disorders, is gathering information from thousands of anosmia and parosmia patients in partnership with ENT UK and the British Rhinological Society to aid the development of therapies.

AbScent recommends ‘smell training’, which involves sniffing rose, lemon, clove and eucalyptus oils every day for around 20 seconds for those trying to regain their sense of smell.

What is parosmia?

Parosmia is the inability of the brain to properly identify an odour’s ‘natural’ smell.

The smell is instead turned into an unpleasant one, commonly described as ‘burned’, ‘rotten’ or ‘faecal’.

Symptoms usually decrease over time for most people with parosmia.

Damage to the olfactory bulb affects how smells are interpreted by the brain.
