HIV

Definition

HIV, or Human Immunodeficiency Virus, is a virus that attacks the immune system, specifically targeting CD4 cells, which are crucial for fighting off infections. If left untreated, HIV can lead to AIDS (Acquired Immunodeficiency Syndrome), a condition where the immune system is severely compromised. Understanding HIV is essential for addressing sexually transmitted infections and promoting effective prevention strategies among adolescents and young adults.

5 Must Know Facts For Your Next Test

1. HIV is primarily transmitted through unprotected sexual contact, sharing needles, and from mother to child during childbirth or breastfeeding.
2. Early detection through regular testing is crucial, as it allows for timely treatment and reduces the risk of transmission to others.
3. Individuals with HIV who adhere to their treatment can achieve an undetectable viral load, meaning the virus cannot be transmitted to sexual partners, known as U=U (Undetectable = Untransmittable).
4. Young people aged 13-24 account for a significant percentage of new HIV diagnoses, highlighting the importance of education and prevention efforts targeting this age group.
5. Stigma surrounding HIV remains a major barrier to testing and treatment, making it essential to promote awareness and understanding of the virus.

Review Questions

• How does HIV affect the immune system and what are its potential long-term consequences if left untreated?
  • HIV targets and destroys CD4 cells, which are essential for a robust immune response. As these cells decrease in number, the body's ability to fight off infections weakens. If untreated, HIV can progress to AIDS, where individuals become susceptible to opportunistic infections that can lead to severe health complications or death. This highlights the critical need for early diagnosis and ongoing treatment.
• Discuss the significance of early detection and treatment of HIV in preventing transmission and improving health outcomes.
  • Early detection of HIV is vital because it enables individuals to start Antiretroviral Therapy (ART) sooner, which helps control the virus and maintain a healthy immune system. When individuals achieve an undetectable viral load through consistent treatment, they cannot transmit the virus to sexual partners. This significantly reduces new infections and enhances overall health outcomes for those living with HIV.
• Evaluate the impact of stigma on individuals living with HIV and how public health initiatives can address these challenges.
  • Stigma surrounding HIV can discourage individuals from seeking testing and treatment due to fear of discrimination or social isolation. This not only affects their mental health but also contributes to higher transmission rates as undiagnosed individuals continue to spread the virus. Public health initiatives play a crucial role in combating stigma by raising awareness, promoting education about HIV transmission and prevention, and creating supportive environments that encourage individuals to seek care without fear of judgment.
