Explain Difference between HIV and AIDS.
HIV (Human Immunodeficiency Virus) and AIDS (Acquired Immunodeficiency Syndrome) are related but distinct conditions. HIV is a virus that attacks the immune system, specifically targeting CD4 cells, which are crucial for the body's ability to fight off infections and diseases. HIV gradually weakens the immune system over time, leaving the body susceptible to opportunistic infections and cancers. However, not everyone with HIV progresses to AIDS.
AIDS is the most advanced stage of HIV infection, characterized by severe immunodeficiency and the presence of opportunistic infections or cancers. AIDS is diagnosed when a person with HIV develops a specific set of symptoms or when their CD4 cell count falls below a certain threshold. Without treatment, AIDS is typically fatal, as the immune system becomes too compromised to fight off even minor infections.
In summary, HIV is the virus that causes AIDS. HIV infection progresses through stages, and AIDS is the final and most severe stage of HIV infection. Effective antiretroviral therapy can prevent the progression of HIV to AIDS and greatly improve the prognosis for individuals living with HIV.
