HIV- AIDS

What is HIV-AIDS?

HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, specifically the CD4 cells, which are critical for defending the body against infections. Over time, HIV weakens the immune system, making it difficult to fight off infections and diseases. If left untreated, HIV can progress to AIDS (Acquired Immunodeficiency Syndrome), the final stage of HIV, where the immune system is severely compromised.

​

Causes of HIV

HIV is transmitted through the exchange of certain body fluids from an infected person. The most common ways HIV is transmitted include:

• Unprotected Sexual Contact: HIV can be spread through vaginal, anal, or oral sex without protection.

• Sharing Needles: HIV can be transmitted through shared needles or syringes contaminated with infected blood.

• Blood Transfusions: In rare cases, HIV can be transmitted through infected blood, although blood screening has made this rare.

• Mother-to-Child Transmission: HIV can be passed from an infected mother to her baby during childbirth or breastfeeding.

• Infected Blood Exposure: Healthcare workers or individuals may contract HIV through accidental contact with infected blood.

​

Symptoms of HIV-AIDS

The symptoms of HIV can vary based on the stage of infection:

• Early Stage (Acute HIV): Flu-like symptoms such as fever, sore throat, swollen lymph nodes, headache, and rash, usually appearing 2-4 weeks after exposure.

• Chronic HIV Stage: This stage may last several years, often without noticeable symptoms, but the virus continues to damage the immune system.

• AIDS Stage: When the immune system is severely weakened, symptoms include rapid weight loss, recurring fever, prolonged swollen lymph glands, chronic diarrhea, and frequent infections or cancers.

​

Diagnosis

HIV is diagnosed through blood or saliva tests that detect the presence of the virus or the antibodies the body produces in response to it. Common diagnostic methods include:

• HIV Antibody Test: Detects antibodies to HIV in the blood or saliva.

• Nucleic Acid Test (NAT): Detects HIV in the blood earlier than an antibody test but is more expensive.

• Combination Test: Detects both HIV antibodies and antigens (proteins produced by the virus).

If diagnosed early, HIV can be managed effectively with medications, allowing individuals to live long, healthy lives.

​

Prevention

Although there is no cure for HIV, there are effective ways to prevent transmission:

• Practice Safe Sex: Use condoms and other barrier methods during sex to reduce the risk of transmission.

• Get Tested Regularly: Regular HIV testing ensures early detection and helps prevent transmission to others.

• Use PrEP (Pre-exposure Prophylaxis): A daily medication that reduces the risk of contracting HIV for people at high risk.

• Do Not Share Needles: Avoid sharing needles or syringes for drug use.

• Mother-to-Child Prevention: HIV-positive mothers can reduce the risk of transmission to their baby with medications during pregnancy and delivery.

HIV-AIDS Medications

HIV-AIDS medications, known as antiretroviral therapy (ART), help control the virus, prevent the progression to AIDS, and improve quality of life. ART involves a combination of medications that work to suppress the viral load in the body, keeping it at undetectable levels and preventing further damage to the immune system. Common classes of HIV medications include:

• Nucleoside Reverse Transcriptase Inhibitors (NRTIs): Block the reverse transcriptase enzyme, preventing HIV from replicating (e.g., Tenofovir, Lamivudine).

• Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs): Also block the reverse transcriptase enzyme but in a different way from NRTIs (e.g., Efavirenz, Rilpivirine).

• Protease Inhibitors (PIs): Prevent HIV from maturing and becoming infectious by blocking the protease enzyme (e.g., Atazanavir, Darunavir).

• Integrase Inhibitors: Prevent HIV from integrating into the host cell's DNA (e.g., Dolutegravir, Raltegravir).

• Entry Inhibitors: Prevent the virus from entering healthy CD4 cells (e.g., Maraviroc).

• Boosters: Drugs like Ritonavir or Cobicistat are used to boost the effectiveness of other HIV medications.

​

Side Effects

While HIV medications are effective at controlling the virus, they can cause side effects. Common side effects include:

• Nausea or vomiting

• Diarrhea

• Headache

• Fatigue

• Rash

• Liver problems

• Changes in cholesterol or blood sugar levels

It’s important to talk to your healthcare provider if you experience side effects, as they may be able to adjust your treatment plan or provide relief for certain symptoms.

Common Questions About HIV-AIDS Medications

​

1. Can HIV be cured?
No, HIV cannot be cured, but it can be controlled with antiretroviral therapy (ART), allowing individuals to live long, healthy lives.

​

2. How effective are HIV medications?
When taken as prescribed, ART can reduce the viral load to undetectable levels, preventing the progression to AIDS and reducing the risk of transmission.

​

3. Can I stop taking HIV medications once my viral load is undetectable?
No, even if your viral load is undetectable, stopping treatment can allow the virus to rebound. Lifelong adherence to ART is necessary.

​

4. What is PrEP?
PrEP (Pre-exposure Prophylaxis) is a medication taken by HIV-negative individuals at high risk of exposure to prevent contracting the virus.

​

5. How often do I need to take HIV medications?
HIV medications are typically taken daily as part of a combination therapy. Following your prescribed schedule is crucial for effective treatment.
