The manifestation of AIDS card lung symptoms generally refers to Pneumocystis carinii pneumonia. Its main manifestation is the clinical manifestation of interstitial pneumonia, mainly chronic cough, fever, chest tightness and dyspnea, etc. However, there are fewer pulmonary signs, and wet rales are generally less likely to be heard in the lungs. Interstitial lesions can be seen on CT of the chest. In patients with AIDS, a diagnosis of Pneumocystis carinii pneumonia requires prompt treatment, as many patients are at risk of death due to respiratory failure. Of course, it is not scientific to diagnose Pneumocystis carinii pneumonia as AIDS alone, because there are many causes of Pneumocystis carinii pneumonia, and patients with other causes of immunocompromised or immunodeficiency are also susceptible to Pneumocystis carinii pneumonia.
