What to do with an upper respiratory tract infection? Firstly, one should choose antimicrobial agents to treat the inflammatory response of the body, that is, anti-infection treatment. It is necessary to check routine blood tests, mycoplasma, C-reactive protein, or undergo sputum pathogen culture. If it is caused by mycoplasma infection, one can choose macrolide antibiotics. If it is due to common bacterial or viral infections, one can choose beta-lactam antibiotics, or some Chinese patent medicine preparations that clear heat and detoxify, all of which can treat diseases of the upper respiratory tract infection.
