HIV/AIDS Comprehensive Guide

What is HIV/AIDS?

HIV (Human Immunodeficiency Virus) is a virus that attacks the body’s immune system, specifically the CD4 cells (T cells), weakening the immune response over time. If untreated, HIV can progress to AIDS (Acquired Immunodeficiency Syndrome), a severe condition where the immune system is too compromised to fight off infections and certain cancers effectively.

Classify HIV/AIDS

Illness: HIV/AIDS is a chronic viral infection that impairs the immune system. AIDS represents the advanced stage of HIV infection.

HIV/AIDS Statistics

• Over 38 million people globally were living with HIV in 2022.
• Approximately 1.5 million new cases are diagnosed annually worldwide.
• With antiretroviral therapy (ART), people with HIV can live long and healthy lives.

Types of HIV/AIDS

1. HIV-1: Most common and aggressive type globally.
2. HIV-2: Less common, primarily found in West Africa, progresses more slowly.

Health Signs and Symptoms

Early Detection: Regular testing is crucial, as early-stage HIV may present mild or no symptoms.

Common Signs and Symptoms:

• Fever
• Fatigue
• Swollen lymph nodes
• Night sweats
• Weight loss
• Chronic diarrhea
• Skin rashes or lesions
• Opportunistic infections in advanced stages

Anatomy and Physiology

HIV/AIDS primarily affects:

• Immune System: CD4 cells, T cells.
• Lymphatic System: Lymph nodes and lymphatic tissues.
• Organs: Lungs, brain, liver, and kidneys in advanced stages.

Causes

Brief Description: HIV is transmitted through the exchange of bodily fluids containing the virus.

Common Causes:

1. Unprotected Sexual Contact: Most common mode of transmission.
2. Sharing Needles: Among people who inject drugs.
3. Mother-to-Child Transmission: During pregnancy, birth, or breastfeeding.
4. Blood Transfusions: Rare in countries with stringent blood screening protocols.
5. Occupational Exposure: Among healthcare workers via needlestick injuries.

HIV/AIDS Stages

1. Acute HIV Infection: Flu-like symptoms shortly after exposure.
2. Chronic HIV Infection: Virus multiplies slowly, often asymptomatic.
3. AIDS: Severe immune system damage, leading to opportunistic infections and cancers.

Prevention

• Consistent use of condoms.
• Regular HIV testing and knowing partner’s status.
• Pre-exposure prophylaxis (PrEP) for high-risk individuals.
• Avoid sharing needles or syringes.
• Ensure blood products are screened.
• Antiretroviral therapy for HIV-positive pregnant women.

HIV/AIDS Diagnosis

Diagnosis involves blood tests to detect HIV antibodies, antigens, or RNA levels.

Tests & Examinations

• HIV Antibody Test: Detects antibodies after the window period.
• Antigen/Antibody Test: Detects HIV earlier by identifying p24 antigen.
• Nucleic Acid Test (NAT): Detects HIV RNA, used in high-risk cases.
• CD4 Count: Assesses immune system health.
• Viral Load Test: Measures HIV in the blood.

Health Professionals

1. Infectious Disease Specialists: Experts in managing HIV/AIDS.
2. Primary Care Practitioners: Provide ongoing care and monitoring.
3. Pharmacists: Manage medications and educate on adherence.
4. Counselors and Social Workers: Offer emotional and social support.

Reasons to See a Professional

• Suspected exposure to HIV.
• Symptoms like persistent fever or swollen lymph nodes.
• Regular health check-ups if at risk.

Process to Find the Right Professional

• Seek recommendations from HIV support organizations.
• Use online health directories.
• Contact local health departments for specialist referrals.

Visit Preparation

• Record possible exposure dates and methods.
• List symptoms and their duration.
• Bring a list of current medications.

Questions to Ask

• What stage is my HIV infection?
• What are my treatment options?
• How can I prevent transmitting HIV?
• Are there side effects to the medications?
• How often should I have follow-up tests?

Diagnosis

HIV/AIDS is diagnosed through blood tests confirming the presence of the virus or antibodies. Advanced testing determines the stage of infection.

Procedures

• Blood Tests: Identify and monitor HIV.
• CD4 Count: Indicates immune health.
• Viral Load Monitoring: Tracks treatment effectiveness.

Treatments

• Antiretroviral Therapy (ART): Daily medication regimen to control the virus.
• Opportunistic Infection Management: Antibiotics, antivirals, or antifungals.
• Preventative Medications: PrEP or PEP for those at risk.

Health Monitoring

• Routine viral load and CD4 count testing.
• Monitoring for side effects of ART.
• Regular screenings for opportunistic infections.

How to Manage HIV/AIDS

• Adhere to ART regimen.
• Attend all scheduled medical appointments.
• Stay informed about advances in HIV care.

Nutrition Dos and Don’ts

Dos:

• Eat a balanced diet with fruits, vegetables, lean proteins, and whole grains.
