Questions & Answers

Q: What are the main transmission routes for HIV?

HIV can be transmitted through unprotected sex, mother-to-child transmission during childbirth or through breast milk, needle sharing, blood transfusions, or organ transplants.

Q: Who is most at risk of HIV infection?

Populations most at risk include commercial sex workers, injecting drug users, individuals with multiple sexual partners, and occupational groups like truck drivers and miners. Uncircumcised males and individuals with other sexually transmitted infections are also at higher risk.

Q: What are the consequences of HIV infection?

Q: What progress has been made in addressing HIV?

Some countries have made significant progress in reducing new infections and improving access to antiretroviral therapy. Sustained political leadership, accurate information and education, condom use, addressing other sexually transmitted infections, and voluntary counseling and testing are key factors in reducing the epidemic.

Summary & Key Takeaways

• HIV is a virus transmitted through sexual intercourse, mother-to-child transmission, needle sharing, blood transfusions, or organ transplants.

• Populations at highest risk include commercial sex workers, injecting drug users, individuals with multiple sexual partners, and certain occupational groups like truck drivers and miners.

• HIV leads to a weakened immune system, opportunistic infections, and has significant health, social, and economic consequences.
