HIV (Human Immunodeficiency Virus) initially infects immune cells, particularly CD4 T cells, weakening the immune system.
The virus replicates inside these cells, progressively reducing their number and impairing the immune system's ability to defend against infections and diseases.
Over time, the ongoing destruction of CD4 cells weakens the immune system to a critical point where it becomes susceptible to opportunistic infections and cancers.
Individuals with advanced HIV infection are at risk of opportunistic infections, such as pneumonia, tuberculosis, and certain cancers, which are defining characteristics of AIDS (Acquired Immunodeficiency Syndrome).
AIDS is diagnosed when the CD4 cell count falls below a certain threshold, indicating severe immune system compromise.
Antiretroviral therapy (ART) helps control HIV replication, slowing disease progression and preventing the development of AIDS.
