HIV is a virus that targets the body’s immune system, which serves as its natural protection against infections and diseases. If HIV is not treated, it can progress to the condition known as AIDS. HIV is transmitted predominantly through the exchange of bodily fluids such as blood, sperm, vaginal fluids, rectal fluids, and breast milk. HIV is a virus that assaults the immune system.
HIV primarily targets a kind of white blood cell called CD4 T cells, which play a key role in immune response coordination. When an individual contracts HIV, the virus enters the body and begins to reproduce within CD4 T cells. The virus gradually affects the immune system over time by lowering the number of these critical immune cells as it multiplies. This weakened immune system makes the body more susceptible to diseases and illnesses that a healthy immune system would normally be able to combat.
While there is no cure for HIV, breakthroughs in medical treatment have allowed people with HIV to live long and healthy lives with good medical care and adherence to treatment regimens. Early detection, treatment, and prevention are critical in limiting the spread of HIV and improving the quality of life for people who are infected.
AIDS is a disease that occurs in the latter stages of HIV infection. It is distinguished by a significantly reduced immune system, which makes the body vulnerable to opportunistic infections and some malignancies that a healthy immune system would typically be able to control. AIDS is a clinical diagnosis based on medical principles and specific criteria.
AIDS causes significant immune system damage, leaving the body exposed to opportunistic infections and some malignancies that a healthy immune system would typically be able to fight off or control. When a person’s immune system becomes significantly impaired and certain clinical criteria are met, they are diagnosed with AIDS. Certain opportunistic infections and a decrease in CD4 T cell counts (a kind of white blood cell essential for immunological function) are among the criteria.

Frequently Asked Questions (FAQS)
Q1. How can I lower my chances of obtaining HIV?
Using condoms (Safe sex practices), avoiding needle sharing, and adopting HIV pre-exposure prophylaxis can help lower the risk of HIV transmission.
Q2. What's the distinction between HIV and AIDS?
HIV (Human Immunodeficiency Virus) is the virus that affects the immune system, whereas AIDS (Acquired Immunodeficiency Syndrome) is a late stage of HIV infection marked by severe immune system damage and vulnerability to opportunistic infections and certain malignancies.
Q3. Is it possible to treat AIDS?
While there is no cure for AIDS, many of the related opportunistic infections and consequences can be managed. Antiretroviral therapy (ART) continues to be an important treatment for both HIV and AIDS.
Q4. What exactly are opportunistic infections?
Opportunistic infections are those that prey on a weakened immune system. Because of their weakened immune systems, people with AIDS are especially vulnerable to certain illnesses.
Q5. Is AIDS a life-threatening disease?
People with AIDS can live for many years with good medical care, adherence to treatment, and management of concomitant diseases. Maintaining health and quality of life requires early discovery, prompt treatment, and ongoing medical care.
