HIV/AIDS Comprehensive Guide

What is HIV/AIDS?

HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, specifically the CD4 cells (T cells), which help the body fight infections. Over time, untreated HIV can lead to AIDS (Acquired Immunodeficiency Syndrome), a condition in which the immune system becomes severely damaged, making the body vulnerable to opportunistic infections and certain cancers.

Classify HIV/AIDS

Condition: HIV/AIDS is a chronic condition caused by a viral infection that progressively weakens the immune system.

HIV/AIDS Statistics

Globally, an estimated 38.4 million people were living with HIV in 2022. In the same year, 1.5 million new infections and 650,000 AIDS-related deaths were reported.

Types of HIV/AIDS

1. HIV-1: The most common type worldwide.

2. HIV-2: Less common and primarily found in West Africa, with slower progression to AIDS.

Health Signs and Symptoms

Early Detection: Symptoms may not appear immediately, making regular testing crucial.

Common Signs and Symptoms:

• Fever

• Chills

• Rash

• Night sweats

• Fatigue

• Swollen lymph nodes

• Mouth ulcers

• Muscle aches

Anatomy and Physiology

Affected Body Parts:

• Immune System: CD4 cells, lymph nodes.

• Digestive System: Opportunistic infections may affect the gastrointestinal tract.

• Neurological System: Can cause cognitive and motor impairments in advanced stages.

• Skin: Susceptible to infections and cancers like Kaposi’s sarcoma.

Causes

Description: HIV is primarily transmitted through bodily fluids.

Common Causes:

1. Unprotected sexual contact.

2. Sharing needles or syringes.

3. Blood transfusions with infected blood.

4. Mother-to-child transmission during pregnancy, childbirth, or breastfeeding.

HIV/AIDS Stages

1. Acute HIV Infection: Flu-like symptoms; high levels of the virus in the blood.

2. Chronic HIV Infection: Virus remains active but reproduces at low levels.

3. AIDS: Severely damaged immune system, marked by opportunistic infections.

Prevention

• Practice safe sex using condoms.

• Regular HIV testing.

• Use of pre-exposure prophylaxis (PrEP).

• Avoid sharing needles or syringes.

• Pregnant women with HIV should receive antiretroviral therapy to prevent transmission.

HIV/AIDS Diagnosis

Common diagnosis involves reviewing medical history, assessing risk factors, and conducting specific tests.

Tests & Examinations

• HIV Antibody Test: Detects antibodies in blood or saliva.

• Antigen/Antibody Test: Detects both HIV antigens and antibodies.

• Nucleic Acid Test (NAT): Detects the virus’s RNA.

Health Professionals

1. Infectious Disease Specialists: Manage and treat HIV/AIDS.

2. Primary Care Physicians: Provide general care and monitor overall health.

3. Pharmacists: Guide medication adherence.

4. Counselors: Offer psychological and emotional support.

Diagnosis

The process typically involves an HIV test followed by a confirmatory test, such as a Western blot or NAT, to determine the presence and progression of the virus.

Procedures

• Blood tests for viral load and CD4 count.

• Physical exams to check for symptoms or complications.

Treatments

1. Antiretroviral Therapy (ART): The cornerstone of HIV treatment.

2. Prophylaxis: Prevents opportunistic infections.

3. Symptom Management: Addresses side effects and associated conditions.

Health Monitoring

• Regular blood tests for viral load and CD4 count.

• Monitoring side effects of ART.

• Home devices: Digital thermometers, blood pressure monitors.

How to manage HIV/AIDS

1. Adherence to ART: Consistent medication use.

2. Regular medical checkups: Routine monitoring.

3. Support groups: Emotional and social support.
