Common symptoms of Covid are well-known by this point in the public and include fatigue, a sore throat, and headaches.

However, a new symptom has appeared to pop up for many Brits who are already vaccinated but get Covid.

As reported by The Independent according to data gathered by the ZOE Health Study app, diarrhoea is a common symptom of Covid for vaccinated Britons.

Data shows that there was a rise in people reporting this symptom in January 2022, and that some of this was related to the Omicron variant of Covid.

However, ZOE did clarify that there seemed to be a “wave of other non-Covid tummy bugs going around too”.

The team said that diarrhoea can be an early symptom of the virus, starting on the first day of infection and getting worse throughout the week.

A member of the ZOE team said: “It usually lasts for an average of two to three days, but can last up to seven days in adults."

The data found this symptom has become less prevalent with each variant, as nearly a third of adults aged over 35 reported having diarrhoea during the Alpha wave, while just one in five said they experienced it during the Omicron and Delta waves.

During the latter two waves of the virus people who had been vaccinated either twice or had also received their booster jab were more likely to be affected by this symptom.

The NHS says diarrhoea is common in adults, and the most important thing to do is to stay hydrated.

The health service also advises to stay home and get plenty of rest, and eat food when you feel able to.
