Symptoms of infection with Omicron variant virus are mostly characterized by fever, malaise, dry cough, sore throat, and loss of taste.
The severity of clinical symptoms after infection varies due to the different physical condition of each person and the amount of virus infected.
Most people who have been vaccinated have mild symptoms after infection, which usually only manifest as upper respiratory tract infection symptoms, such as nasal congestion, runny nose, sore throat, etc., and are usually accompanied by fever, malaise, dizziness and other symptoms.
Some patients may develop lower respiratory tract infections, causing pneumonia and symptoms such as chest pain, cough and sputum. Critically ill patients may progress to symptoms such as dyspnea. There are also some asymptomatic infections with no clinically obvious symptoms.
Omicron is a mutated strain of Neocoronavirus, which is more infectious than the Neocoronavirus and Delta mutated strains, and has a shorter incubation period after infection. Be sure to take good personal protection, gather less often, and actively participate in physical exercise to improve your body’s immunity.
