As you may already know, the symptoms of Covid-19 include fever, dry cough, and loss of smell and taste.

However, two early signs of coronavirus infection have recently been discovered, and it is neither of the above.

Most people who have Covid-19 have a bad headache and constant tiredness , according to the COVID Symptom Study app.

More than 80% of all patients reported a headache as one of their first symptoms, while 72%, reported fatigue.

All age groups were more likely to experience headaches and fatigue.

However, the three most common signs of coronavirus remain: fever, cough and loss of taste, which are also key to the infection.

"Only 9% of Covid-19 positive adults, aged 18-65, have not experienced a headache or fatigue. Of course, headaches and fatigue can also occur for other reasons, so they do not require immediate testing. ”

In fact, in the app, only 1% of people who reported only fatigue and / or headaches, without any of the other three signs, tested positive.

Headaches are very common, and are not necessarily indicative of a coronavirus infection, but then accompanied by three of the main symptoms, can pose a problem.

Fatigue, meanwhile, can be caused by a number of health conditions.

You should consider talking to a doctor about your fatigue if it lasts more than a few weeks and you can not think of any obvious reason for it.

Some patients have also reported sore throat, diarrhea, and hiccups in addition to the most common signs.
