The respiratory symptoms of AIDS are actually the symptoms associated with AIDS combined with respiratory diseases. For example, when AIDS is combined with tuberculosis infection, symptoms such as cough and sputum with hemoptysis, chest pain, and dyspnea may occur, and generalized symptoms such as fever, night sweats, malaise, loss of appetite, and weight loss may occur. In AIDS combined with Pneumocystis carinii pneumonia, progressive dyspnea, fever, dry cough, and chest pain may occur. In the case of AIDS combined with fungal infection, the symptoms may include irritating cough, white mucous sputum, sometimes with blood in the sputum, or even hemoptysis. The symptoms of AIDS combined with different complications and respiratory manifestations are different. According to the different manifestations and the relevant laboratory tests of the patient, the complications of AIDS can be clarified and can be treated symptomatically.
