Mixed airway infections are usually airway infections that are caused by two or more causative organisms. Mixed airway infections are airway infections in which the causative organism is not a single pathogen, but may be caused by a combination of two or more pathogenic organisms. For example, in the early stage of upper and lower respiratory tract infections, the infection may start as a viral infection, but since there are no specific antiviral drugs for viral infections, and the local or systemic resistance decreases during the prolonged course of the disease, it may result in a mixed infection with other pathogens, such as gram-positive cocci, on top of the viral infection. If you are diagnosed with mixed airway infections, you should choose antibiotics such as cefixime granules and cefadroxil reasonably under the guidance of your doctor for treatment. Quit smoking and drinking in daily life, and do not eat spicy and stimulating foods such as chili peppers, which will affect the recovery of the disease.
