One real story is that a young man had a high fever as his first symptom. It was really sudden and made him feel very weak. He also had a loss of taste and smell which was quite strange for him. It affected his appetite a lot as he couldn't enjoy his food like before.
There was an older gentleman who didn't have the typical symptoms at first. He just felt extremely tired all the time. He thought it was because he was getting old. But then he developed a headache that wouldn't go away. After getting tested, he found out he had COVID - 19. His case shows that the symptoms can be very different for different people, and sometimes the less common symptoms can be the first sign of the virus.
