AIDS is a highly harmful infectious disease caused by HIV infection. HIV is a virus that attacks the body's immune system. It takes the most important CD4 T lymphocytes in the human immune system as the main target, destroying the cells in large quantities and depriving the body of immune function. Therefore, the human body is prone to various diseases, and malignant tumors can occur, and the mortality rate is high. The incubation period of HIV in the human body averages 8 to 9 years.
Before AIDS, you can live and work for many years without any symptoms. HIV-infected patients will develop into AIDS patients after several years or even an incubation period of 10 years or longer. Due to the extremely low resistance of the body, various infections such as herpes zoster, oral mold infection, tuberculosis, special Pathogenic microorganisms caused by enteritis, pneumonia, encephalitis, Candida, Pneumocystis and other pathogens caused by serious infections, etc., often occur later in malignant tumors, and long-term consumption, and even systemic death.
