Eye infection and seven other coronavirus symptoms that suggest you have Covid-19

So how do you know if you've already had Covid-19?
The best way is to take a test, but there are eight symptoms that may suggest you have already been infected.
Oxford boffins suggest that the coronavirus, like many emerging infections, may have spread invisibly for a month before its effects became clear at the end of February.


The first symptom may have been an eye infection:
The new research indicated that an eye infection such as conjunctivitis may be a symptom of Covid-19.
The College of Optometrists said: "It is recognized that any upper respiratory tract infection may result in viral conjunctivitis as a secondary complication, and this is also the case with Covid-19.
"However, it is unlikely that a person would present with viral conjunctivitis secondary to Covid-19 without other symptoms of fever or a continuous cough as conjunctivitis seems to be a late feature where is has occurred.”

The second symptom may have been a dry cough:
Perhaps the most recognizable of the Covid-19 symptoms, given how different it can sound compared to a typical cough.
More often than not it will last for at least half a day.

The third symptom may have been Mental Fatigue:
Although this is not an official symptom of Covid-19, sufferers have reported experiencing it.
Thea Jourdan told The Daily Mail that she first thought she may have been infected when she got a tickle in her throat and a headache.
The mum-of-three then began to experience brain fog.
She said: ”Initially I felt exhausted, as if I was dragging myself through treacle and had no choice but to go to my bed. I had no meaningful cough and I wasn’t running a fever," the Hampshire woman told the publication.
"But I had a peculiar sensation of something settling deep within my lungs, almost like breathing in talcum powder.”

The fourth symptom may have been a high temperature:
Although the high temperature may vary for different people, a rise in body temperature generally counts as a fever once it reaches 37.7C (100F).

The fifth symptom may have been difficulty breathing:
Most young people or those without pre-existing health conditions are unlikely to experience this symptom.
Dyspnea - the term for when someone has difficulty breathing - may be coupled with a tightness in the chest, rapid breathing and heart palpitations.

The sixth symptom may have been loss of sense of smell and taste:
The British Association of Otorhinolaryngology warned that losing your sense of smell and taste may mean you have Covid-19.
The ear, nose and throat specialist recommended anyone with such symptoms self-isolate immediately.
The association said: ”Evidence from other countries that the entry point for the coronavirus is often in the eyes, nose and throat areas.
"We have also identified a new symptom (loss of sense of smell and taste) that may mean that people without other symptoms but with just the loss of this sense may have to self-isolate - again to reduce the spread of the virus.”

The seventh symptom may have been a stomach ache:
Along with a loss of appetite, a stomach ache may be linked to Covid-19.
They found that 48.5% of 204 people who have been infected by the coronavirus in China's Hubei province had digestive symptoms such as diarrhea.

The final symptom may have been physical fatigue:
Another common symptom of Covid-19, as well as cold, flu and many viruses in general, is feeling tired or fatigued.
