About Lesson

I. Introduction to HIV/AIDS

HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, specifically targeting CD4 cells (T cells), which are crucial for immune function. AIDS (Acquired Immunodeficiency Syndrome) is the most advanced stage of HIV infection when the immune system is severely damaged, and the body can no longer fight off infections and certain cancers.

II. Epidemiology of HIV/AIDS

HIV/AIDS is a global pandemic affecting millions worldwide. According to UNAIDS, as of [latest statistics], approximately [number] people are living with HIV globally. The epidemic varies significantly by region and demographic factors such as age, gender, and socioeconomic status.

III. Pathophysiology of HIV

HIV is a retrovirus that uses RNA as its genetic material. Upon entering the bloodstream, HIV primarily targets CD4 cells, hijacking their machinery to replicate and spread. This process leads to a gradual decline in CD4 cell count, weakening the immune system over time.

IV. Transmission of HIV

HIV is transmitted through certain body fluids, including blood, semen, vaginal fluids, rectal fluids, and breast milk. The primary modes of transmission include unprotected sexual contact, sharing needles or syringes with someone who is infected, and from mother to child during childbirth or breastfeeding.

V. Clinical Stages of HIV Infection

  1. Acute HIV Infection: The first stage of HIV infection, occurring within the first few weeks after exposure. Symptoms may resemble flu-like illness, including fever, headache, rash, and swollen lymph nodes.

  2. Chronic HIV Infection: As the infection progresses, HIV enters a chronic stage where it can persist for many years if untreated. During this stage, people with HIV may not experience any symptoms or may have mild symptoms.

  3. Progression to AIDS: Without effective treatment, HIV can progress to AIDS. AIDS is diagnosed when the CD4 cell count drops below 200 cells per cubic millimeter of blood (normal range is 500-1,600 cells/mm³) or if the person develops certain opportunistic infections or cancers.

VI. Common Opportunistic Infections

People with advanced HIV/AIDS are at increased risk of developing opportunistic infections. These infections take advantage of a weakened immune system and can include tuberculosis, pneumonia, candidiasis (thrush), cytomegalovirus (CMV), and certain cancers like Kaposi’s sarcoma.

End-of-Topic Questions with Answers:

  1. What distinguishes HIV from AIDS?

    • HIV is the virus that causes AIDS. HIV attacks the immune system by targeting CD4 cells. AIDS is diagnosed when the immune system is severely damaged, and the person becomes susceptible to opportunistic infections.
  2. How does HIV transmission occur?

    • HIV transmission occurs through contact with certain body fluids, including blood, semen, vaginal fluids, rectal fluids, and breast milk. Transmission routes include unprotected sexual intercourse, sharing needles or syringes, and from mother to child during childbirth or breastfeeding.
  3. What are the stages of HIV infection?

    • The stages include acute HIV infection (early stage with flu-like symptoms), chronic HIV infection (long-term asymptomatic stage), and AIDS (advanced stage with severe immune suppression).
  4. Why are opportunistic infections significant in HIV/AIDS?

    • Opportunistic infections are significant because they indicate a severely weakened immune system in HIV/AIDS patients. They can be life-threatening and require prompt medical intervention.

Curated List of Online Resources:

  1. CDC – HIV Basics: Detailed information on HIV/AIDS, prevention, and treatment from the Centers for Disease Control and Prevention.

  2. UNAIDS – Global HIV Statistics: Global statistics, reports, and updates on the HIV/AIDS epidemic worldwide.

  3. AIDSinfo – HIV Treatment and Guidelines: Comprehensive guidelines on HIV treatment, antiretroviral therapy (ART), and management of HIV-related complications.

  4. AVERT – HIV and AIDS Information: Educational resources covering HIV prevention, testing, and living with HIV/AIDS.
