What is the HIV
HIV Doctor in Delhi, or Human Immunodeficiency Virus, is a virus that attacks the immune system of the human body. It specifically targets CD4 cells, which are a type of white blood cell crucial to the immune system's function. HIV weakens the immune system over time, making it harder for the body to fight off infections and diseases.
There are two main types of HIV:
HIV-1: This is the most common and widespread type of HIV. It is responsible for the majority of HIV infections worldwide.
HIV-2: This type of HIV is less common and primarily found in West Africa. It tends to progress more slowly than HIV-1.
HIV is transmitted through contact with certain body fluids, including blood, semen, vaginal fluids, rectal fluids, and breast milk from a person who has HIV. The most common modes of transmission include unprotected sexual intercourse, sharing needles or syringes for drug use, and from mother to child during childbirth or breastfeeding.
HIV infection can lead to acquired immunodeficiency syndrome (AIDS) if left untreated. AIDS is the final stage of HIV infection when the immune system is severely damaged, and the individual becomes vulnerable to a wide range of opportunistic infections and certain cancers.
While there is no cure for HIV, it can be effectively managed with antiretroviral therapy (ART), which helps control the virus's replication and slows down the progression of the disease. Early diagnosis and timely initiation of treatment are crucial for managing HIV and preventing its progression to AIDS. Additionally, practicing safe sex, using clean needles, and taking other preventive measures can help reduce the risk of HIV transmission.
What is the difference HIV and Aids?
HIV (Human Immunodeficiency Virus) and AIDS (Acquired Immunodeficiency Syndrome) are related but distinct terms that describe different stages of the same disease process:
1. HIV (Human Immunodeficiency Virus):
· HIV is the virus that causes the infection.
· When a person is infected with HIV, the virus enters their bloodstream and begins to attack and destroy CD4 cells (a type of white blood cell), weakening the immune system.
· HIV infection can remain asymptomatic for many years, during which time the virus continues to replicate and damage the immune system.
· People with HIV may experience flu-like symptoms shortly after infection, but these symptoms usually go away, and the person may feel healthy for a long time.
· HIV can be controlled and managed with antiretroviral therapy (ART), which helps reduce the viral load in the body and maintain or restore immune function.
· Many people with HIV who receive appropriate medical care and treatment can live long and healthy lives.
2. AIDS (Acquired Immunodeficiency Syndrome):
· AIDS is the advanced and final stage of HIV infection.
· It is characterized by a severely weakened immune system, with a significant decline in CD4 cell count.
· Individuals with AIDS are at high risk of developing opportunistic infections (infections that typically do not affect people with healthy immune systems) and certain cancers.
· AIDS is diagnosed when a person with HIV infection has a CD4 cell count below a certain threshold (usually less than 200 cells/mm³ of blood) or has specific AIDS-defining illnesses, regardless of CD4 count.
· Without medical intervention and treatment, AIDS can be life-threatening.
In summary, HIV is the virus that initially infects a person, while AIDS is the advanced stage of HIV infection characterized by a severely compromised immune system and the occurrence of specific opportunistic infections or cancers. With proper medical care and early intervention, the progression of HIV to AIDS can often be delayed or prevented through the use of antiretroviral therapy (ART) and appropriate healthcare measures. It's important for individuals at risk of HIV infection to get tested, seek medical care, and adhere to treatment plans to manage the virus and prevent the development of AIDS.
