AIDS (AIDS), short for acquired immune trap syndrome, is a serious infectious disease caused by the human immunodeficiency virus.
AIDS invades the body through sexual contact and transfusion of blood or blood products, specifically destroying helper T-lymphocytes and causing severe impairment of the body’s cellular immune function. The disease progresses from asymptomatic carriers to persistent generalized lymph node enlargement syndrome and AIDS-related syndrome, and finally to severe opportunistic infections and malignant tumors. The morbidity and mortality rate is extremely high and has become a public health problem of the greatest concern in the world today.
