HIV/AIDS

HIV (Human Immunodeficiency Virus) is a virus that attacks the body’s immune system, specifically the CD4 cells (T cells), which are crucial for fighting off infections. If left untreated, HIV can lead to AIDS (Acquired Immunodeficiency Syndrome), the final stage of HIV infection, where the immune system is severely damaged, making the body vulnerable to opportunistic infections and certain cancers. While there is no cure for HIV, it can be managed with antiretroviral therapy (ART), allowing individuals to live long, healthy lives and reducing the risk of transmitting the virus to others.

Causes and Transmission:

HIV is transmitted through contact with certain body fluids from an infected person. The most common modes of transmission include:

  • Unprotected Sexual Contact: HIV is primarily spread through vaginal, anal, or oral sex with someone who has the virus, especially if no barrier methods (e.g., condoms) are used.
  • Sharing Needles: Using needles or syringes that have been used by someone with HIV can transmit the virus.
  • Mother-to-Child Transmission: HIV can be passed from an infected mother to her baby during pregnancy, childbirth, or breastfeeding.
  • Blood Transfusions: Although rare, receiving blood products that are contaminated with HIV can result in transmission, particularly in areas where blood screening is not rigorous.
  • Accidental Needle Sticks: Health workers may be at risk if they are accidentally pricked with a needle containing HIV-infected blood.

    Symptoms:

    HIV symptoms vary depending on the stage of infection:

    Acute HIV Infection (2-4 weeks post-exposure):

    • Flu-like symptoms such as fever, chills, rash, night sweats, muscle aches, sore throat, fatigue, swollen lymph nodes, and mouth ulcers.
    • This stage is known as acute retroviral syndrome (ARS) or primary HIV infection.

    Chronic HIV Infection:

    • The virus continues to multiply but at lower levels. Individuals may not have symptoms but can still transmit the virus.
    • Without treatment, this phase can last for a decade or longer.

    AIDS:

    • Rapid weight loss
    • Recurring fever or profuse night sweats
    • Extreme and unexplained tiredness
    • Prolonged swelling of the lymph glands
    • Diarrhea that lasts for more than a week
    • Sores of the mouth, anus, or genitals
    • Pneumonia
    • Red, brown, pink, or purplish blotches on or under the skin or inside the mouth, nose, or eyelids
    • Memory loss, depression, and other neurologic disorders

    Diagnosis:

    HIV is diagnosed through specific blood tests:

    • HIV Antibody Test: Detects antibodies that the body produces in response to HIV infection, typically within 3-12 weeks of exposure.
    • Antigen/Antibody Test: Can detect HIV earlier than the antibody test by identifying both HIV antibodies and antigens (a part of the virus).
    • Nucleic Acid Test (NAT): Detects the virus itself and is typically used for early diagnosis.

    If an HIV test is positive, follow-up tests will confirm the diagnosis and determine the stage of the infection.

    Treatment:

    There is no cure for HIV, but antiretroviral therapy (ART) can effectively control the virus:

    Antiretroviral Therapy (ART):

    • Combination Therapy: Involves taking a combination of HIV medicines (called an HIV regimen) every day. ART reduces the amount of HIV in the body (viral load) to undetectable levels, which helps protect the immune system and prevents transmission.
    • Adherence: Strict adherence to ART is crucial for its effectiveness. Missing doses can lead to drug resistance, making treatment less effective.
    • Regular Monitoring: Individuals on ART need regular blood tests to monitor their viral load and CD4 cell count.

    Prevention:

    Preventing HIV involves several strategies:

    • Use Condoms: Consistent and correct use of condoms during sexual activity significantly reduces the risk of HIV transmission.
    • Pre-Exposure Prophylaxis (PrEP): A daily medication for people at high risk of HIV, PrEP can reduce the risk of getting HIV from sex by about 99%.
    • Post-Exposure Prophylaxis (PEP): Taking antiretroviral medicines within 72 hours after a possible exposure to HIV can prevent infection.
    • Do Not Share Needles: Avoid sharing needles, syringes, or other injection equipment.
    • Routine Testing: Regular HIV testing helps in early detection and management, reducing the risk of transmission.

    Self-Care:

    Living with HIV requires consistent self-care to manage the condition and maintain overall health:

    • Adherence to ART: Take medications as prescribed and never miss a dose.
    • Healthy Diet: Eat a balanced diet to support the immune system.
    • Regular Exercise: Maintain physical fitness to improve overall health and reduce stress.
    • Mental Health Support: Seek support for emotional and mental health challenges.
    • Regular Medical Check-ups: Monitor your health regularly and report any new symptoms to your healthcare provider.
