HIV: The Silent Attacker of the Immune System

HIV, or the human immunodeficiency virus, is a virus that targets CD4 cells, which are essential for battling infections, and assaults the immune system. HIV can spread by contact with specific body fluids, including blood, body contact. Unprotected contact, sharing syringes or needles, are common mechanisms of transmission.

Phases:

Acute HIV Infection: Within a few weeks of exposure, the first stage of the infection takes place and is frequently marked by flu-like symptoms.

Chronic HIV Infection: In the absence of care, HIV multiplies and progressively compromises immune function.

The most advanced stage of acquired immunodeficiency syndrome, or AIDS, is characterised by a severely impaired immune system, which increases susceptibility to opportunistic infections and malignancies.

AIDS, or acquired immunodeficiency syndrome, develops when HIV has significantly damaged the immune system. Individuals with AIDS have a much higher risk of developing various infections and cancers that the body would usually be able to fight off. Without management, AIDS is fatal. However, with the guidance of an experienced HIV Doctor in Delhi, individuals with HIV can receive proper medical care, including antiretroviral therapy (ART), to live long and healthy lives, often preventing the progression to AIDS.

Our Services

HIV (Human Immunodeficiency Virus) spreads through certain body fluids from a person who has HIV. Here are the primary ways HIV can be transmitted:

Unprotected Contact

Sharing Needles or Syringes

Blood Transfusions

Occupational Exposure (Healthcare workers exposed to HIV-infected blood, people)

Contact with Infected Blood

Important Points

HIV is Not Spread By:

Casual contact, such as hugging, shaking hands, or sharing dishes.

Air, water, or insects like mosquitoes.

Saliva, sweat, tears, or urine, unless they contain visible blood and come into contact with mucous membranes or open wounds.

Key Points of Pep

Post-Exposure Prophylaxis (PEP) is an emergency protocol aimed at preventing HIV infection after potential exposure. Here are the key points:

Purpose: PEP is used to prevent HIV infection after a possible exposure to the virus.

Timing: It must be started within 72 hours (3 days) after exposure for maximum effectiveness.

Duration: PEP involves taking antiretroviral medications daily for 28 days.

Effectiveness: Highly effective when started promptly and taken consistently.

Situations for Use: Recommended for unprotected body contact, needle sharing, occupational exposure (e.g., healthcare workers).

Impact of HIV in Immune System

HIV, or Human Immunodeficiency Virus, affects the immune system by specifically targeting and attacking a type of white blood cell called CD4 cells, also known as T-helper cells. CD4 cells play a crucial role in coordinating the body's immune response to infections and diseases. Here's how HIV impacts the immune system:

CD4 Cell Destruction: HIV infects and replicates within CD4 cells, leading to their destruction over time. As the number of CD4 cells decreases, the body's ability to mount an effective immune response is compromised.

Weakened Immune Response: With fewer CD4 cells available to coordinate the immune response, the body becomes less able to defend itself against infections, viruses, bacteria, and other pathogens. This results in increased susceptibility to opportunistic infections and diseases.

Increased Vulnerability to Infections: HIV-related immune suppression leaves the body vulnerable to a wide range of infections that would normally be controlled by a healthy immune system. These infections can include bacterial infections, fungal infections, viral infections, and parasitic infections.

Opportunistic Infections: Opportunistic infections are those that prey on an immune system that is compromised. HIV/AIDS patients are at increased risk of opportunistic infections such as pneumonia, tuberculosis, candidiasis (yeast infection), cytomegalovirus (CMV), toxoplasmosis, and cryptococcal meningitis.

Reduced Ability to Fight Cancer: A weakened immune system also reduces the body's ability to identify and destroy cancer cells. HIV/AIDS patients have an increased risk of certain types of cancers, including Kaposi's sarcoma, non-Hodgkin lymphoma, and cervical cancer.

Chronic Inflammation: HIV infection can lead to chronic inflammation throughout the body, even in the absence of active infections. Chronic inflammation contributes to tissue damage, organ dysfunction, and accelerated ageing in HIV/AIDS patients.
