What is a significant difference between HIV and AIDS?

The significant difference between HIV and AIDS lies in their definitions and roles in the progression of the disease. HIV, or Human Immunodeficiency Virus, is the virus that attacks the immune system by specifically targeting CD4 T cells, which are crucial for the body's ability to fight off infections and diseases. If left untreated, HIV can lead to a progressive decline in immune function.

AIDS, or Acquired Immunodeficiency Syndrome, is the most severe phase of HIV infection. It is characterized by a significantly weakened immune system, making the body more susceptible to opportunistic infections and certain cancers. AIDS is not a virus itself but rather a syndrome that results from the advanced stages of HIV infection, where the immune system has become so compromised that it can no longer defend against common infections.

Understanding this distinction is important for recognizing how HIV progresses to AIDS and the implications for treatment and management of health in individuals living with the virus. This knowledge also highlights the importance of prevention and early intervention in managing HIV to prevent the progression to AIDS.
