5 signs that you've had a "light" covid. Doctors from Oxford have concluded that when a person has a mild form of coronavirus, they may have 5 characteristic symptoms that most people don't even pay attention to: 1. Temporary anosmia. Loss of sense of smell, which is caused by damage to nerve endings. Many people don't pay attention to this symptom, confusing it with stuffiness. 2. Fatigue syndrome. Patients experience fatigue and a feeling of apathy due to the intoxication process. That’s felt immediately after a night's rest. 3. Conjunctivitis. Coronavirus can affect the mucosa of the eyeball and cause inflammation, burning, and pus accumulation. 4. "Covid" fingers. A rash on the fingers or toes. This symptom is usually seen in children and young adults. 5. Suspicion of a stroke. Coronavirus can affect not only the lungs, but also the brain. Some patients have had symptoms of a pre-stroke condition: loss of consciousness; dizziness; numbness of facial muscles.
