Many people know that there are three main Covid symptoms to look out for – but there are several others that could be a sign of the virus.

The NHS states that anyone with one – or more – of symptoms including high temperature, continuous cough or loss in smell could be fighting off the potentially deadly virus.

But the US officially recognises a wide range of symptoms of coronavirus sufferers – including headaches to loss of appetite, as well as more extreme symptoms such as diarrhoea, vomiting and skin and mouth issues, Wales Online reports.

GPs recently sent an open letter to the Government saying that people with “cold” like symptoms such as a runny nose or nausea should get a Covid test. A runny nose is also recognised by American health authorities as a Covid symptom.

Here is a list of the symptoms people have reported and the ones officially recognised:

Three main Covid symptoms listed by the NHS

IYA Covid vaccine stats

1. A high temperature

If you feel hot to touch on your chest or back (you do not need to measure your temperature).

2. A new continuous cough

If you are coughing a lot for more than an hour, or three or more coughing episodes in 24 hours (if you usually suffer with a cough, it may be worse than usual).

3. A loss or change to your sense of smell or taste

If you have noticed you cannot smell or taste anything or things smell or taste different to the way they normally do.

Symptoms officially recognised in the US (in addition to NHS listed symptoms)

4. Headache

A headache is recognised as an official symptom by the Centre for Disease Control and Prevention in the USA.

According to researchers at Zoe Symptom Study, headaches are one of the earliest signs of Covid and more common than the classic symptoms of a cough, fever and loss of smell.

However, headaches are very common and most people with a headache will not have Covid.

5. Shortness of breath or difficulty breathing

Shortness of breath or difficulty breathing is recognised as an official symptom by the Centre for Disease Control and Prevention in the USA.

Millions of people reported to the Zoe Symptom Study that they experienced a shortness of breath.

People noticed their breath was short after doing simple tasks such as getting up, walking to a different room or even talking.

6. Fatigue

Fatigue is recognised as an official symptom by the Centre for Disease Control and Prevention in the USA.

According to researchers at Zoe Symptom Study, fatigue is one of the early signs of the disease. It is not the same feeling as tiredness, more an extreme form of feeling “wiped out” that persists despite a good night sleep.

It may make it difficult to walk up stairs, do normal chores or even get out of bed. It can also make it hard to concentrate on things. Some people have described it as “brain fog”.

7. Muscle or body aches

Muscle or body aches is recognised as an official symptom by the Centre for Disease Control and Prevention in the USA.

Muscle pain has been found as a possible symptom of Covid -19 by researchers at Zoe Symptom Study.

Covid-related muscle pains can range from being mild to quite debilitating, especially when they occur alongside fatigue. For some people this muscle pain stops them from doing day-to-day tasks.

However, muscle pain can be caused by a number of reasons so most people with aches and pains will not have Covid.

8. Sort throat

A sore throat is recognised as an official symptom by the Centre for Disease Control and Prevention in the USA.

Data from Zoe Covid symptom study app, looking at reported symptoms of those in the UK, has shown that a sore throat can be a symptom of Covid.

It is a lesser known symptom, and often an early sign of the disease more common in children and adults up to the age of 65.

People using the app have reported having a sore throat that feels similar to what you might experience during a cold or laryngitis.

COVID-related sore throats tend to be relatively mild and last no more than five days.

9. Congestion or runny nose

Congestion or runny nose is recognised as an official symptom by the Centre for Disease Control and Prevention in the USA.

10. Nausea or vomiting

Nausea or vomiting is recognised as an official symptom by the Centre for Disease Control and Prevention in the USA.

11. Diarrhoea

Diarrhoea is recognised as an official symptom by the Centre for Disease Control and Prevention in the USA.

Zoe researchers found that diarrhoea can be a symptom of Covid and affects a reasonable proportion of people with the illness.

Having COVID-19 diarrhoea alongside many other symptoms is associated with an increased risk of needing hospital support.

Diarrhoea caused by COVID-19 is similar to the upset tummy you might get from a regular stomach bug, such as rotavirus or norovirus. Diarrhoea is common in children and adults and usually clears up by itself.

Researchers think Covid causes diarrhoea because the virus can invade cells in the gut and disrupt its normal function.

Reported but not officially confirmed

12. Skin rash (Covid fingers and toes)

Data from Zoe Covid symptom study app, looking at reported symptoms of those in the UK, suggests that some people who suffered with Covid-19 saw changes to the skin on their fingers and toes.

It is not clear what causes these changes but could be linked to the immune response to the virus.

The rashes are usually itchy and may make it difficult to sleep.

They can appear as prickly heat or chickenpox-type rash, which is the most common itchy red bumps and can occur anywhere in the body. It can sometimes be crusty, weepy or form blisters and does not tend to affect the face.

Another type of rash that could form is a hive-type rash, which appears as sudden raised bumps on the skin which can come and go quickly over hours. This can happen in any part of the body.

Other less common rashes include Pityriasis Rosea-like, light-sensitive rashes and vasculitis rashes.

13. Covid tongue

Some people are reporting to the Zoe Covid app changes to their mouth and tongue. These include mouth ulcers and their tongue appearing coated or patchy.

Other changes include having a dry mouth and fungal infections as well as pain or muscle aches while chewing.

14. Hoarse voice

People reported to the Zoe Covid study app that they experienced changes to their voice which affected the sound of their speech.

A hoarse voice isn’t a very common symptom of Covid-19; however, during the beginning of the pandemic lots of clinical staff reported experiencing a hoarse voice during their illness.

A hoarse voice can sound, and feel, different from person to person. For example, your voice might become more croaky, raspy, or rough, quieter or even change in pitch. If you have a hoarse voice, you might feel like it requires more effort to speak.

We know that the Covid-19 virus affects the tissues in our respiratory system of which the voice box (larynx) is a part of. This explains why some people get a hoarse voice during their infection.

While it’s not a particularly strong predictor of Covid-19, if you have an unexplained hoarse voice Zoe researchers recommend you get a test.

15. Chest pain

A small amount of people using the Zoe Symptom app experienced significant chest pains, but it is important to remember chest pains can be a sign of something seriously wrong, like a heart attack of blood clot in the lung.

It is likely caused by the virus directly affecting muscles and lungs. While it is rare, people with Covid who experience chest pains have a higher risk of needing hospital support, especially if the chest pain is alongside confusion or shortness of breath.

16. Abdominal pains

According to Zoe researchers, abdominal pains are a fairly rare symptom of Covid but could be a generalised pain around the middle of your belly.

If you’re experiencing a localised pain that appears in only one area of your belly, it’s unlikely to be COVID-19. Localised abdominal pain should still be checked by a healthcare professional because it could be caused by something else that needs treatment, such as appendicitis.

17. Loss of appetite

A loss of appetite could be a symptom of Covid, according to Zoe researchers.

Researchers say that skipping meals was first spotted in care homes, carers noticed residents were off their food during their illness.

A loss of appetite is a normal part of being unwell and can be caused by feeling too sick or tired to eat a meal.

18. Delirium

Delirium is an important symptom of Covid-19 in elderly people, according to Zoe researchers.

There are two types, hyperactive delirium, where someone abruptly changes their character and starts acting strangely, they could become agitated or distressed and even aggressive.

The second type is hypoactive delirium, which is more common and harder to spot.

People with hypoactive delirium become withdrawn and less responsive or engaged in what’s going on around them, and sometimes drowsy.

They can also become incontinent, because they don’t realise they need the toilet, and stop eating and drinking. Sometimes a person with delirium can be disoriented in time or place, which is not always obvious unless they are asked directly.

Delirium was also found as a key symptom of Covid in old people in a study conducted at St Thomas’ Hospital in London.
