The terrible thing about AIDS is that the virus damages the immune system, leading to severe impairment of immune system function, triggering a variety of opportunistic infections and tumors, and ultimately leading to death. The full name of AIDS is Acquired Immunodeficiency Syndrome, which is caused by Human Immunodeficiency Virus (HIV) infection, which mainly invades and destroys lymphocytes, resulting in impaired immune function. When infected with HIV, the immune system’s ability to defend against various pathogens is significantly reduced, making it susceptible to opportunistic infections, commonly such as Pneumocystis carinii pneumonia and Candida albicans esophagitis. At the same time, the decrease in the number of immune cells and the inhibition of their function will also cause the body to be more prone to malignant tumors. The prognosis of AIDS is poorer and the death rate is higher. If you feel unwell, it is recommended that you consult a doctor in time and standardize your treatment under the guidance of a professional doctor.
