One in five people infected with Covid is experiencing a little-known symptom, according to a study. Ear condition tinnitus has been added to ZOE study's list of conditions which the virus could exacerbate.
Tinnitus is characterised by a ringing in the ear. A survey carried out by health organisation ZOE showed that of 14,500 people surveyed, some 5,000 reported both testing positive and suffering some ringing in their ears.
ZOE co-founder Professor Tim Spector warned that the new symptom should be taken "really seriously" as it could indicate that the virus is attacking the body in new ways.
