Background

Respiratory tract infection (RTI) is one of the most common diseases in humans, which can occur in any gender, age group and region. Most respiratory tract infections are caused by viruses, chlamydia or mycoplasma. These pathogens are diverse, and the clinical symptoms and signs they cause are relatively similar. Their clinical manifestations mainly include rhinitis, pharyngitis, laryngitis, tonsillitis and other symptoms. In severe cases, they can cause tracheitis, bronchitis, pneumonia, etc. However, infections caused by different pathogens vary in terms of treatment methods, curative effects and disease courses.
