Definition of HIV and AIDS

Human Immunodeficiency Syndrome (HIV) is a retrovirus that infects and destroys helper T cells of the immune system, causing the marked reduction in their numbers.  Once the level of helper T cells drops low enough, the disease progresses from HIV to AIDS (acquired immunodeficiency syndrome).  This stage is marked by:

  • swollen lymph nodes
  • weight loss
  • fevers
  • infections in the mouth
  • diarrhea
  • fatique
  • memory loss

HIV and AIDS are spread through:

  • sexual contact with an infected person
  • contact with infected blood
  • breast milk passed from mother to child
