Most of the patients with whooping cough are caused by Pertussis bacilli, which is a kind of bacteria. Therefore, the preferred treatment drug for this type of whooping cough bacilli is macrolide. Azithromycin or erythromycin can be selected for treatment. Of course, in the case of pertussis infection, macrolide antibiotics, such as cephalosporins, can also be used to treat patients with bacterial infection. During the treatment, patients must drink more warm water and avoid eating irritating food. At the same time, it is also necessary to maintain good indoor ventilation, avoid dry air, eat more fresh vegetables and fruits to supplement vitamins, and ensure adequate sleep and rest, which can effectively prevent symptoms from worsening and enable patients to recover faster.
