That’s fallen with subsequent variants and vaccination, with up to one in five people (16-20 percent) experiencing diarrhoea with either Delta or Omicron if they have had either two or three doses of the vaccine.
Other gastrointestinal symptoms of Covid include headache, loss of smell, loss of appetite, sore throat, chest pain and no cough.
The symptoms accompanying your diarrhoea may therefore provide a greater indicator of Covid than experiencing it in isolation.
If you have diarrhoea, it’s important to keep drinking and eating if you can, says the NHS.
