HIV attacks the immune system by targeting CD4+ T cells
Transmission occurs through specific body fluids during sexual contact, blood exposure, or from mother to child
Modern antiretroviral therapy can manage HIV as a chronic condition
Prevention strategies like PrEP and consistent medical care are highly effective
HIV represents a complex viral infection that has significantly impacted global health since its identification in the early 1980s. Despite substantial medical advances, understanding this virus remains critical for effective prevention and treatment. Today, people living with HIV can lead full, healthy lives with proper medical care and support.
Human Immunodeficiency Virus (HIV) is a retrovirus that specifically attacks the immune system. The virus targets CD4+ T cells, which are essential components of the body's immune defense mechanism. When HIV enters the body, it begins a complex process of replication that gradually weakens the immune system's ability to fight infections.
The virus operates by inserting its genetic material into host cells, effectively hijacking their reproductive mechanisms. As the virus multiplies, it destroys CD4+ T cells, leading to a progressive decline in immune function. What makes HIV particularly challenging is its ability to create viral reservoirs that can remain dormant even during treatment.
HIV transmission occurs through specific body fluids, including blood, semen, vaginal fluids, and breast milk. Sexually transmitted diseases (STDs) can increase the risk of transmission by creating potential entry points for the virus.
The primary transmission routes include:
Unprotected sexual contact
Sharing needles or injection equipment
Mother-to-child transmission during pregnancy or breastfeeding
Rare instances of healthcare-related exposure
Modern antiretroviral therapy (ART) has transformed HIV from a fatal diagnosis to a manageable chronic condition. Treatment typically involves a combination of medications designed to prevent viral replication and support immune system function. The goal is to achieve an undetectable viral load, which effectively prevents transmission to sexual partners.

Prevention remains crucial in controlling HIV spread. Key strategies include:
Pre-exposure prophylaxis (PrEP)
Consistent condom use
Regular HIV testing
With modern medical advances, individuals with HIV can expect to live long, healthy lives. Ongoing medical care, consistent medication, and a supportive healthcare approach are essential for managing the condition effectively.
HIV is the virus that causes AIDS, which is the most advanced stage of HIV infection when the immune system is severely damaged.
Currently, there is no cure for HIV, but antiretroviral therapy can effectively manage the virus and prevent its progression.
Modern HIV tests are highly accurate, with most able to detect the virus within 2-4 weeks of exposure.
Yes, with proper medical care and treatment, people with HIV can live full, healthy lives.
Use protection during sexual activity, avoid sharing needles, and consider PrEP if you're at high risk.
Care you can trust. Doctronic is clinically validated with 99% treatment plan alignment.
