The main symptoms of coronavirus (UK National Health Service July 2020) are:
• a high temperature
• a new, continuous cough - this means coughing a lot for more than an hour, or 3 or more coughing episodes in 24 hours (if you usually have a cough, it may be worse than usual)
• a loss or change to your sense of smell or taste – this means you've noticed you cannot smell or taste anything, or things smell or taste different to normal
Most people with coronavirus have at least one of the symptoms above.
