If pneumonia and other diseases co-exist, such as tuberculosis accompanied by pneumonia, after anti-infection treatment, the symptoms of pneumonia are much better, but there is no obvious change in tuberculosis. This situation should be treated for tuberculosis. For example, anti-tuberculosis drugs can be used under the guidance of doctors, and isoniazid and rifampicin are commonly used in clinical practice.
