Most of the causative agents of upper respiratory tract infections are viruses, which are self-limiting. When the patient is infected with virus, clinical symptoms such as cough, coughing, sore throat, fever, peripheral joint pain, etc. appear, while due to their own immunity, viral infection will gradually reduce, fever symptoms will gradually decline, sore throat and muscle pain symptoms will also gradually improve until the body temperature returns to normal and symptoms such as cough and sore throat are significantly relieved in order to achieve self-cure. Upper respiratory tract infections are self-limiting and can be treated clinically with supportive symptomatic treatment, while paying attention to rest and avoiding exposure to cold. Eat more fresh vegetables and fruits to supplement rich minerals and vitamins to improve the immunity of the patient’s organism and promote the recovery of the disease.
