What is HIV?

Human Immunodeficiency Virus (HIV) is a virus that attacks the body’s immune system, specifically the CD4 cells (T cells), which are crucial for fighting infections. If untreated, HIV can lead to Acquired Immunodeficiency Syndrome (AIDS), a condition that severely weakens the immune system and increases the risk of opportunistic infections and certain cancers (Centers for Disease Control and Prevention [CDC], 2023a).

Signs and Symptoms

The symptoms of HIV can vary, but they may include:

• Acute HIV Infection (2-4 weeks after exposure):

  • Flu-like symptoms: Fever, fatigue, sore throat, swollen lymph nodes, and rash.

  • These symptoms may last for a few days to several weeks and can be mistaken for other viral infections (Mayo Clinic, 2023).

• Chronic HIV Infection:

  • Many individuals may not have symptoms for years but can still transmit the virus.

  • When symptoms do occur, they may include prolonged fatigue, weight loss, and recurrent fever (CDC, 2023b).

• AIDS (Advanced Stage):

  • Severe immune system damage leading to opportunistic infections or cancers (CDC, 2023a).

Incubation Period

The incubation period for HIV varies, but the acute stage typically occurs 2 to 4 weeks after exposure. The chronic phase can last for several years, and without treatment, it can progress to AIDS (Mayo Clinic, 2023).

Transmission

HIV is primarily transmitted through:

• Unprotected sexual contact: Vaginal, anal, or oral sex with an infected person.

• Sharing needles: Injection drug use can lead to transmission through contaminated blood.

• Mother-to-child transmission: An infected mother can pass the virus to their child during childbirth or breastfeeding (CDC, 2023a).

U=U (Undetectable = Untransmittable)

• U=U means that individuals with HIV who achieve and maintain an undetectable viral load through consistent antiretroviral therapy (ART) cannot transmit the virus to their sexual partners. This is a significant advancement in HIV treatment and prevention (Prevention Access Campaign, 2023).

• Achieving an undetectable viral load typically takes at least six months of effective treatment. Regular medical care and adherence to ART are crucial for maintaining an undetectable status (CDC, 2023b).

Complications of Untreated HIV

• Opportunistic Infections: These are infections that occur more frequently in individuals with weakened immune systems, such as tuberculosis and certain cancers.

• Neurological Disorders: HIV can affect the brain and nervous system, leading to cognitive impairment and mental health issues (Mayo Clinic, 2023).

• Increased Risk of Other STIs: Individuals with HIV are at greater risk of contracting other sexually transmitted infections (CDC, 2023b).

Prevention

• Consistent Use of Condoms:

  • Using condoms during sexual activity can significantly reduce the risk of HIV transmission, although it does not eliminate the risk entirely (CDC, 2023a).

• Pre-Exposure Prophylaxis (PrEP):

  • PrEP is a medication taken by HIV-negative individuals to reduce their risk of contracting HIV. When taken consistently, it is highly effective (CDC, 2023b).

• Regular Testing:

  • Regular HIV testing is crucial for sexually active individuals, particularly those with multiple partners or at higher risk (CDC, 2023a).

• Open Communication with Sexual Partners:

  • Discussing HIV status and prevention strategies with partners can help reduce the risk of transmission (Planned Parenthood, 2023).

Testing and Treatment

• Testing: HIV can be diagnosed through several types of tests, including rapid tests, laboratory tests, and home testing kits (CDC, 2023b).

• Treatment: While there is currently no cure for HIV, antiretroviral therapy (ART) can effectively manage the virus, allowing individuals to live long, healthy lives. Regular medical care is essential for monitoring viral load and overall health (Mayo Clinic, 2023).

Key Takeaways

• HIV is a manageable chronic condition with proper treatment and care.

• U=U signifies that individuals on effective treatment cannot transmit HIV, providing a powerful tool for prevention.

• Open communication, regular testing, and preventive measures are essential for maintaining sexual health.
