Ultimately, HIV is a virus that attacks the immune system and AIDS is a term that can only be used when HIV has caused severe damage to the immune system.
How is HIV different from AIDS?
AIDS is a condition
While HIV is a virus that may cause an infection, AIDS (which is short for acquired immunodeficiency syndrome) is a condition. Contracting HIV can lead to the development of AIDS. AIDS, or stage 3 HIV, develops when HIV has caused serious damage to the immune system.
Which is worse HIV or AIDS?
AIDS is the disease caused by the damage that HIV does to your immune system. You have AIDS when you get dangerous infections or have a super low number of CD4 cells. AIDS is the most serious stage of HIV, and it leads to death over time.
Can you get AIDS without HIV?
AIDS is a syndrome, or range of symptoms, that may develop in time in a person with HIV who does not receive treatment. A person can have HIV without developing AIDS, but it is not possible to have AIDS without first having HIV.
