Explanation:

1. AIDS is a disease where the immune system is destroyed. The original statement had "abused" which is incorrect.
2. HIV is a viral infection (not bacterial) that attacks the immune system.
3. Opportunistic infections occur in individuals with weakened immune systems (correct as written).
4. HIV is transmitted through blood, semen, and vaginal secretions (correct as written).
5. During the asymptomatic stage of HIV, there are no outward signs of infection. The original said "symptomatic" which is wrong.
6. Every day about 1,000 young people become infected with HIV (correct as written).
7. Health care officials consider HIV/AIDS to be a pandemic (not just an epidemic).
8. Abstinence from sexual activity and injecting drugs greatly reduces the risk of HIV infection (correct as written).

For the steps of how HIV attacks the body's cells:

1. After attaching to the cell surface, HIV fuses with the cell membrane.
2. Then, the viral RNA enters the cell.
3. Reverse - transcriptase converts the viral RNA into DNA.
4. The viral DNA integrates into the host cell's DNA.
