Depression, fatigue, and many other neurological and psychiatric symptoms are also common in people with mild coronavirus infection, a recent study shows.
The results are based on data from 215 studies and 100,000 patients.
The most common neurological and psychiatric symptoms were loss of sense of smell or taste, weakness and exhaustion, depression, headaches, and anxiety.
Symptoms were also very common in patients whose coronavirus infection did not require hospitalization.
Of these, 55% had fatigue, 52% had loss of sense of smell, 47% had muscle pain, 45% had loss of taste, and 44% had headache.
The data did not reveal exactly where the symptoms came from, but the underlying condition may be, for example, an inflammatory condition of the brain, the researchers write.
The study was published in the Journal of Neurology, Neurosurgery and Psychiatry.
