The current strain of the virus responsible for the new crown pandemic is an omicron variant, which lacks specificity in the symptoms of infection.
The symptoms of omicron infection are atypical and therefore more subtle during transmission. In terms of clinical manifestations, the symptoms of Omicron infection were similar to those of upper respiratory tract infections caused by other viruses, and lacked specificity, which made clinical differential diagnosis difficult, and the spread of the virus became more insidious.
Infected cases are mainly mild and common type, and the symptoms are relatively mild. The main clinical manifestations include cough, sore throat, fever, etc. Some patients have symptoms such as nasal congestion, runny nose, fatigue and headache. In addition, patients had atypical imaging changes. Overall, the proportion of patients with severe disease is also not very high.
It is recommended that patients should seek prompt medical attention when the above symptoms occur and be treated accordingly under the guidance of a doctor.
