Prediction method of Omicron infection

Individuals can't judge whether they are infected with COVID-19 Omicron variants only by symptoms, so they need to go to medical institutions for nucleic acid testing in time.

Compared with other variants, the symptoms of COVID-19 Omicron mutant infection are not typical, including sore throat, runny nose, headache and other symptoms similar to upper respiratory tract infection, while the typical symptoms such as loss of smell and taste and elevated body temperature are rare, so we can't test ourselves only by symptoms.
