From its emergence in the early 1980s to the present day, HIV/AIDS has left an indelible mark on communities worldwide, challenging medical professionals, researchers, policymakers, and society as a whole. Understanding the complexities of HIV/AIDS, from its virology to its socio-economic impacts, is essential to fight the ongoing battle against this formidable foe. Lets understand the condition and its details so that we can take the practical steps necessary to manage and prevent it.

What Is HIV?

HIV, or Human Immunodeficiency Virus, is a virus that targets the immune system, the body's natural defense against illness. HIV attacks explicitly CD4 cells, a type of T cell, which play a crucial role in maintaining a healthy immune system by fighting infections and diseases. Unlike other viruses, HIV cannot be eradicated by the human body. As a result, once a person contracts HIV, they are infected for life.

Stages Of Progression

The progression of HIV occurs in various stages listed below:

Acute HIV Infection: This happens 2-4 weeks after exposure. The virus replicates rapidly, and the infected person may experience flu-like symptoms.

Chronic HIV Infection (Clinical Latency): HIV continues to multiply but at lower levels. The person may not exhibit symptoms, but the virus is still active.

AIDS (Acquired Immunodeficiency Syndrome): This is the final stage of HIV infection, where the immune system is severely damaged, leading to an increased vulnerability to opportunistic infections and certain cancers.

What Is AIDS?

AIDS, or Acquired Immunodeficiency Syndrome, represents the most severe phase of HIV infection. At this stage, the body's immune system is so severely damaged that it struggles to fend off infections and diseases, which a healthy immune system could easily combat. Not everyone who has HIV progresses to this stage, especially with the availability of effective treatments.

The progression from HIV to AIDS is defined by

  1. A significant drop in the number of CD4 cells.
  2. The presence of specific opportunistic infections, such as tuberculosis, certain types of pneumonia, and cancers like Kaposi's sarcoma.
  3. With modern antiretroviral therapy (ART), many people living with HIV can prevent the progression to AIDS and live long, healthy lives.

HIV Symptoms

Acute HIV infection (2-4 weeks after exposure): This stage is often characterized by flu-like symptoms, including fever, chills, rash, night sweats, muscle aches, sore throat, fatigue, swollen lymph nodes, and mouth ulcers. These symptoms may last a few days to several weeks and are often mistaken for other viral infections.

Chronic HIV infection: During this stage, the virus is less active but still replicating. People may not exhibit any symptoms, or they may experience mild symptoms. This phase can last for many years without treatment.

AIDS Symptoms

  1. Unexplained and significant weight loss.
  2. Persistent high temperatures and excessive sweating during sleep.
  3. Extreme and unexplained tiredness
  4. Prolonged swelling of the lymph glands
  5. Diarrhea that lasts for more than a week
  6. Frequent lung infections like Pneumonia
  7. Red, brown, pink, or purplish blotches appear on or under the skin or inside the mouth, nose, or eyelids.
  8. Memory loss, depression, and other neurologic disorders

Types of HIV Tests

HIV Test

  1. Antibody Tests: These detect antibodies to HIV in blood or oral fluid. Antibodies are proteins the body makes in response to an infection. Most rapid tests and home tests are antibody tests.
  2. Combination Tests (Antibody/Antigen Tests): These tests can detect HIV antibodies and antigens (a part of the virus). Antigens are present during acute HIV infection before antibodies develop.
  3. Nucleic Acid Tests (NATs): These tests detect the virus in the blood. They can identify HIV in the early stages but are more expensive and less commonly used as initial screening tests.

When to Get Tested

  1. After potential exposure: It is recommended to get tested 2-4 weeks after possible exposure and then retest after three months to confirm the result.
  2. Regular testing: People at higher risk of HIV should get tested regularly. This includes individuals with multiple sexual partners, those who inject drugs, and men who have sex with men (MSM).

How Does One Transmit HIV?

  1. Blood
  2. Semen (cum) and pre-seminal fluid (pre-cum)
  3. Rectal fluids
  4. Vaginal fluids
  5. Breast milk

The virus must enter the bloodstream of the HIV-negative person for transmission to occur. 

Common routes of transmission include

  1. Sexual contact: Unprotected vaginal, anal, or oral sex with an HIV-positive person.
  2. Sharing needles: Using needles, syringes, or other drug injection equipment previously used by someone with HIV.
  3. Mother-to-child transmission: This can occur during pregnancy, childbirth, or breastfeeding. However, with proper medical care, the risk can be significantly reduced.
  4. Contaminated blood transfusions or organ transplants: Although rare in countries with rigorous screening processes, HIV can be transmitted through transfusions of infected blood or organ transplants.

HIV Viral Load Affects Transmitting HIV

ART can reduce the viral load to undetectable levels. An undetectable viral load means the virus is present at such low levels that it cannot be transmitted sexually. This is known as "Undetectable = Untransmittable" (U=U). ART not only helps in reducing the transmission risk but also improves the overall health and lifespan of people living with HIV.

Groups at Higher Risk for HIV

  1. Men who have sex with men (MSM): This group has a higher prevalence of HIV due to factors like higher rates of partner change and anal intercourse, which carries a higher transmission risk.
  2. People who inject drugs (PWID): Sharing needles and other drug paraphernalia increases the risk of HIV transmission.
  3. Sex workers: Engaging in unprotected sex with multiple partners elevates the risk.
  4. Transgender individuals: This group faces higher rates of HIV due to stigma, discrimination, and high-risk behaviors.
  5. People in prisons: The prevalence of HIV is higher in prison populations due to factors like unprotected sex and sharing needles.

Risk Factors For HIV/AIDS?

  1. Age: Young adults and adolescents are at higher risk due to riskier sexual behaviors and lower rates of condom use.
  2. Gender: Women, particularly in sub-Saharan Africa, are more vulnerable to HIV due to biological and socio-economic factors.
  3. Race and ethnicity: In the United States, African Americans and Hispanic/Latino communities are disproportionately affected due to socio-economic disparities and access to healthcare.

Where Is HIV More Common?

Sub-Saharan Africa

This region has the highest burden of HIV, with nearly 70% of the global HIV-positive population. Factors include limited access to healthcare, high rates of other STIs, and socio-economic challenges.

Caribbean

This region has a high prevalence of HIV, influenced by factors such as stigma, limited healthcare access, and high rates of sex work.

Eastern Europe and Central Asia

These regions have seen rising HIV rates, primarily driven by injecting drug use and limited access to preventive services.

HIV/AIDS Treatment

Antiretroviral Therapy (ART)

ART is the cornerstone of HIV treatment. It involves taking a combination of HIV medicines every day. ART helps reduce the viral load to undetectable levels, improves the immune system's function, and prevents the progression to AIDS.

Regular Monitoring

Regular check-ups and blood tests are essential to monitor the viral load and CD4 counts, ensuring the effectiveness of the treatment and adjusting it as necessary.

Healthy Lifestyle: Maintaining a healthy lifestyle, including a balanced diet, regular exercise, and avoiding smoking and excessive alcohol, supports overall health.

Mental Health Support

Psychological support is crucial as living with HIV can be stressful. Support groups, counseling, and mental health services can help manage stress and improve quality of life.

Challenges During HIV/AIDS

Stigma and Discrimination: People living with HIV often face stigma and discrimination, which can hinder access to healthcare, employment, and social support. Education and awareness are crucial to combating stigma.

Access to Treatment: In many parts of the world, access to ART and healthcare services is limited. Efforts to improve healthcare infrastructure and reduce economic barriers are vital.

Preventive Measures of HIV/AIDS

  1. Safe Sex Practices: Using condoms, reducing the number of sexual partners, and regular testing can prevent HIV transmission.
  2. Pre-Exposure Prophylaxis (PrEP): PrEP is a daily medication for people at high risk of HIV. It significantly reduces the risk of contracting HIV.
  3. Post-Exposure Prophylaxis (PEP): PEP involves taking HIV medicines within 72 hours after potential exposure to the virus to prevent infection.
  4. Needle Exchange Programs: These programs provide clean needles to people who inject drugs, reducing the risk of HIV transmission.

Conclusion

Understanding HIV and AIDS, their symptoms, transmission, and management is essential for preventing the spread of the virus and supporting those living with it. Through education, awareness, and compassion, we can work towards a world where HIV/AIDS is no longer a significant health threat.
