PCP pneumonia, also known as Pneumocystis carinii, generally has the potential for most patients to survive close to the level of a healthy person if not accompanied by serious diseases such as AIDS or malignant tumors. In the presence of AIDS, malignant tumors, and other diseases, the survival time is likely to be shortened. It is not possible to generalize about the exact survival time. PCP pneumonia is primarily caused by infection with Pneumocystis carinii, a conditional infectious disease of the lungs, and patients with malignant tumors, AIDS, and those who have had liver and lung transplants are more likely to get the disease than the general population. How long a person lives after the disease is cured has a lot to do with his or her physical condition. Generally speaking, if the patient does not have AIDS, malignant tumors and other diseases, after the cure, if you can take good care of your body, you can get and normal people almost the same survival time. If the patient is suffering from AIDS, malignant tumors and other diseases, timely cure may also affect the physical condition and shorten the survival time. In order to prolong the life, patients should follow the doctor’s advice after the cure, keep observing the changes in the body and return to the hospital for regular checkups.
