The NHS expanded the list of officially recognised Covid-19 symptoms, just days after free testing ended in England. Nine new symptoms were added to the original three from the early days of the pandemic, including common ailments such as a sore throat, headaches, and diarrhoea.

The WHO lists the following as likely symptoms of Covid-19:
