The NHS recently added nine new symptoms to the official coronavirus list.
A number of symptoms have been listed since the virus broke out in late 2019 and had remained unchanged up until last week. However, different covid variants have brought with them different kinds of symptoms - some of which are more common than others.
The NHS website hasn't listed all symptoms, as it says the "symptoms are very similar to symptoms of other illnesses, such as colds and flu". The World Health Organisation (WHO) has their own list which also notes various other symptoms including 'serious' ailments.
