Also known as: Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome
HIV is a virus that attacks the immune system, specifically CD4 T-cells. Without treatment, it may progress to AIDS, where the immune system is severely compromised. Modern antiretroviral therapy can effectively control the virus.
HIV affects approximately 39 million people worldwide. Since the beginning of the epidemic, it has claimed over 40 million lives, but advances in treatment have transformed it from a fatal diagnosis to a manageable chronic condition.
The virus destroys CD4 T-cells, which are crucial for immune defense. Without treatment, the CD4 count gradually declines over years, eventually reaching a point where the body cannot fight off opportunistic infections and cancers — this stage is defined as AIDS (CD4 count below 200 cells/mm3 or presence of AIDS-defining illnesses).
Modern antiretroviral therapy (ART) can suppress the virus to undetectable levels, allowing people with HIV to live near-normal lifespans. Crucially, undetectable equals untransmittable (U=U) — people with sustained viral suppression cannot sexually transmit HIV.
Pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV infection in people at high risk, reducing sexual transmission by approximately 99% when taken as prescribed.
People with HIV/AIDS often experience the following symptoms.
A flu-like illness occurring 2-4 weeks after infection, with fever, sore throat, swollen lymph nodes, rash, and muscle aches. Many people may not recognize these symptoms as HIV-related.
Persistently swollen lymph nodes in multiple areas, which may be painless. This can persist throughout the chronic infection stage.
As the immune system weakens, infections such as oral thrush, Pneumocystis pneumonia, tuberculosis, and toxoplasmosis may develop.
Unintentional weight loss exceeding 10% of body weight, often accompanied by chronic diarrhea and weakness in advanced untreated disease.
Certain factors may increase your likelihood of developing HIV/AIDS.
Common approaches to managing hiv/aids. Always consult a healthcare provider for personalized treatment.
Combination of antiretroviral drugs taken daily that suppress viral replication to undetectable levels. Treatment is lifelong and should be started as soon as possible after diagnosis.
Modern ART often combines multiple drugs into a single daily pill (such as bictegravir/emtricitabine/tenofovir), greatly simplifying treatment adherence.
Cabotegravir/rilpivirine injections given every 1-2 months offer an alternative to daily oral medication for virally suppressed patients.
Regular CD4 count and viral load testing to ensure treatment effectiveness. Annual screening for comorbidities including kidney function, bone density, and cardiovascular risk.
HIV testing includes rapid antibody tests, combination antigen/antibody (4th generation) tests, and nucleic acid tests (NAT). A reactive screening test requires confirmatory testing. The window period varies from 10 days (NAT) to 90 days (antibody-only tests).
Get tested if you have had potential exposure to HIV. Seek immediate medical attention for post-exposure prophylaxis (PEP) within 72 hours of a high-risk exposure.
Steps that may help reduce the risk of developing or worsening hiv/aids.
Use condoms consistently during sexual contact
Pre-exposure prophylaxis (PrEP) for high-risk individuals
Post-exposure prophylaxis (PEP) within 72 hours of potential exposure
Never share needles or injection equipment
If left untreated or poorly managed, hiv/aids may lead to:
There is currently no cure, though a very small number of people have been functionally cured through stem cell transplants. ART effectively controls the virus, allowing a near-normal lifespan.
An undetectable viral load means the amount of HIV in the blood is too low to measure with standard tests. People who are undetectable cannot transmit HIV sexually (U=U).
The CDC recommends at least one HIV test for everyone aged 13-64 as part of routine healthcare, and annual testing for people with risk factors.
