Eight signs you’ve already had Covid-19 – including brain fog

Most of us are now aware of the main symptoms of Covid-19 – a new, continuous cough, a high temperature and loss of taste/smell.

If you have any of these symptoms you are told to self isolate – and book a test straight away.

But with one in three people with coronavirus believed to be asymptomatic, it means many of us will have already had the virus without even knowing.

If you’ve had coronavirus you are likely to have some semblance of immunity for up to six months after.

But how do you know if you’ve already had Covid-19 without displaying symptoms, or taking an antibody test?

Here are eight signs you’ve already had the virus, as reported by Birmingham Live. These symptoms could show up months after you’ve had the virus, according to experts.

Cough – with a difference

Many will know that one of the main symptoms of coronavirus is a persistent cough.

The cough sounds different to the type of cough you could usually get – and even differ from a “smokers cough” too.

Red eyes

If you suffered from red eyes, there is a chance you had coronavirus.

The College of Optometrists said: "It is recognised that any upper respiratory tract infection may result in viral conjunctivitis as a secondary complication, and this is also the case with Covid.

"However, it is unlikely that a person would present with viral conjunctivitis secondary to Covid without other symptoms of fever or a continuous cough as conjunctivitis seems to be a late feature where is has occurred."

Breathlessness

Many of those who have had coronavirus struggle with dyspnea, or difficulty breathing.

This could be coupled with a highness in the chest, rapid breathing and heart palpitations.

Stomach trouble

A newly published study by the American Journal of Gastroenterology linked stomach problems to coronavirus.

It was found that 48.5% of 204 people who tested positive for coronavirus in Hubei, China, had digestive symptoms such as diarrhoea.

Fatigue

One of the main issues those who have long-term problems with Covid are facing is fatigue.

For some of those who have had Covid, fatigue and tiredness is incredibly difficult to overcome, even months after having the virus.

Brain fog

Some of those who have had Covid are dealing with brain fog for months after battling the bug.

Speaking seven months after having Covid, Mirabai Nicholson-McKellar, said: “Brain fog seems like such an inferior description of what is actually going on. It’s completely crippling. I am unable to think clearly enough to [do] anything.”

High temperature

If you’ve previously had a high temperature, there is a chance you may have had Covid, as it is one of the main symptoms.

A high temperature is considered a fever when it reaches 37.7C (100F).

Sudden loss of taste or smell

This was the last of the main symptoms to be added to the NHS list.

Taste and smell might return after recovering from the virus – but in many cases it takes months to improve.
