The virus that can lead to acquired immunodeficiency syndrome (AIDS) if not treated is the human immunodeficiency virus, commonly known as HIV. HIV attacks the body’s immune system by targeting and destroying CD4 cells, which play a crucial role in protecting the body against infections. If HIV is left untreated, it can progress to AIDS, a condition characterized by a severely weakened immune system, making an individual much more susceptible to opportunistic infections and certain cancers.

Other options do not relate to the development of AIDS. Hepatitis A is a viral infection that affects the liver but does not compromise the immune system in the same way as HIV. Holistic care refers to an approach in health care that considers the whole person and their well-being, rather than a specific illness, and has no direct connection to HIV or AIDS. Hormones are chemical messengers in the body that regulate various physiological processes but do not cause or lead to HIV or AIDS.
