Patients with advanced AIDS are indeed more distressed. This is because once AIDS reaches its onset, patients often have a combination of high fever, weight loss, swollen lymph nodes throughout the body, a variety of conditional infections and the development of tumors. Some patients may even develop dementia due to the onset of encephalitis and meningitis. The average survival period for untreated patients, once they enter this period, is only about 12-18 months. Since AIDS patients do not have effective body resistance at this time, bacterial, viral and fungal infections often cannot be effectively controlled even after medication is used, and most of the patients will be accompanied by the development of malignant tumors, which will progress more rapidly.
