But just because you have diarrhoea, it doesn’t necessarily mean that you coronavirus.
In the UK, you only need to get tested for Covid if you develop a high fever, a new, continuous cough, or a loss of smell or taste.
You should book a Covid test as soon as you develop any of the key symptoms.
Self-isolate at home until you receive your test results. If it comes back positive, you should remain isolated for at least 10 days.
