One of the more unusual side effects of suffering from 'long Covid' has proven to be the long-term impact on people's senses of taste and smell.

But, for some, the effects go beyond not being able to taste or smell food and drink - in a minority of cases, people are literally left with a nasty taste in their mouths and noses.

This is something reporter Jaymelouise Hudspith, from north Wales, encountered when she tested positive for the virus in December, despite months of being "extremely careful".

At first, the North Wales Live reporter thought the odour was inside her flat and scrubbed it from top to bottom.

But, when she was able to smell a disgusting mixture of rotten egg, rotting meat and sewage when at the supermarket or even while out walking her dog, she knew something wasn't right.

She discovered she was suffering from parosmia, a condition which alters a person's sense of smell, as a consequence of 'long Covid' and has spoken of how it has taken over her everyday life.

She was left unable to smell normally

When I contracted Covid-19 at the start of December 2020, it came as a massive shock.

Like many people across the UK, I had been extremely careful - I'd sanitised my hands constantly, I wore face masks everywhere, I worked from home and I only left the house when I absolutely had to.

Nevertheless, I tested positive for the virus. Luckily, my symptoms weren't too severe and I didn't need hospital treatment.

I had spent the best part of a year writing about the pandemic and the effect it had had on millions of other people - and individuals - across the UK, so I knew what to expect.

I was even prepared for the 'long Covid' symptoms of fatigue and the occasional bout of 'brain fog' (the number of times I've forgotten I've left something in the oven is unbelievable) which I still suffer with to this day.

However, what I wasn't prepared for was some of the more unexpected - and more unusual side effects - that the coronavirus can cause.

Nearly three months on from my positive test, my sense of taste and smell were back - but not in the way I was hoping.

I started to notice this horrific odour, which I can only describe as a mix of rotten eggs, rancid meat and fish, all mixed with sewage.

It is thought Long Covid affects more than 60,000 people in the UK

Thinking it was something in my home, I scrubbed it top to bottom searching for anything that may have caused the smell. I even cleaned all the drains and the bins in the hope of ridding myself of the foul stench.

But it didn't work, and I started to notice the putrid odour more and more, and I could smell it no matter where I was.

I could smell it while out walking my dog, at the supermarket, while cooking, even while brushing my teeth.

If my partner hadn't also been going through the same thing, I would have thought I was going mad.

It wasn't until some time later that I realised what it was, and what had caused all this - long Covid.

A doctor told me I had probably developed parosmia as a result of the virus, a condition that effectively distorts your sense of smell.

Commonly reported by long Covid suffers, parosmia causes you to detect particularly offensive smells almost persistently.

Not much is known yet about Long Covid

For me, the smells include a strong smell of fish, rotten eggs, rancid meat, and sewage. But other suffers have also reported smelling sweat, smoke, chemicals, yeast, and even blood.

And sadly there isn't much that can be done to alleviate the effects of this revolting condition, and there is no way to tell when it will let up.

It is believed parosmia affects roughly 10 per cent of coronavirus suffers who originally lost their sense of smell and taste.

Experts say it suggests that the sense of smell is returning, but it could last for extended periods, and it can make some foods intolerable. With reports that fried food, egg, garlic, coffee and chocolate are among the worst offenders.

Though for me, it isn’t just food that triggered these revolting odours that leave me nauseated and stressed.

Recently my taste had been affected as a result of long Covid too.

For the last week, I haven’t been able to stomach anything but the plainest foods (porridge oats, plain pasta and toast), any flavoursome food tastes so foul I have to spit it out and I’m left wanting to vomit.

At its worst, even weak orange squash tasted like rotten egg and bad tuna.

Long Covid has completely robbed me of my enjoyment of food and drink, and because my diet is now so limited I'm starting to struggle with my energy levels to get through the day.

It is so much worse than losing your senses completely.

While I know I am lucky compared to some people who have contracted this virus, living day in day out with these odours and tastes is really debilitating. Especially when there is little I can do to get better.

AbScent has set up a Facebook group and, with support from the British Rhinological Society (BRS) and ENT UK, an online guide called NoseWell to support Britons suffering from anosmia and parosmia.

They are gathering information from thousands of anosmia and parosmia patients to aid the development of therapies.

The charity recommends anyone affected by parosmia to undergo "smell training", which involves sniffing rose, lemon, clove and eucalyptus oils every day for around 20 seconds in a bid to slowly regain their sense of smell.
