HIV Treatment and Prevention
HIV, or the human immunodeficiency virus, is one which attacks the human immune system. HIV treatment and prevention are critical steps in stopping the spread of this disease. Left untreated, the HIV virus can cause a serious, even life-threatening disorder known as AIDS, or Acquired Immune Deficiency Syndrome.
To understand why HIV is so unusual, you first need to know how your immune system works. Your immune system is the part of your body that protects you from infections caused by viruses and bacteria.
When someone is immunocompromised (meaning that their immune system is weakened), they are especially vulnerable to what might otherwise be only a minor infection the body could fight off.
Why HIV is Different from Other Viruses
HIV is different from other kinds of viruses, because the HIV virus seeks out and kills special cells known as T cells (also called CD4 helper cells). T cells are a type of lymphocyte, or white blood cell. They form a critical line of defense against diseases and infections.
How T Cells Protect Your Body
T cells are very specialized. They have very specific functions such as identifying foreign invaders and helping other cells, called B cells. B cells create targeted antibodies to locate and kill bacteria and viruses.
By attacking the T cells, HIV disrupts the immune system, making it much harder for people who are HIV positive to fight back against infections. Click here.
Additionally, HIV is a retrovirus. This means that it has an enzyme called reverse transcriptase that allows it to insert its own DNA into the host cells. It uses this to force T cells to make copies of the virus, spreading more of itself throughout the body.
HIV also has a high rate of mutation, which means that there are many different strains of the disease. Because there are so many variants, a single vaccine that could protect people from HIV is very, very difficult to create. This is one reason why why early HIV treatment and prevention are so important.
How Long Does It Take for Untreated HIV to Cause AIDS?
HIV is like a viral time-bomb. Someone can be infected with it and not know they are HIV positive. Some people may carry the virus for a decade or more before symptoms begin to show. The average time between HIV infection and developing AIDS is usually within 5 to 10 years. That timeline is not set though; it can be much shorter, or even longer, depending on the patient.
Antivirals: HIV treatment and Prevention
HIV treatment usually centers around antiviral therapies, or ART. Antivirals are designed to lower the viral “load” in the infected person’s body. By reducing the number of virons (active copies of the virus) down to an undetectable level, HIV positive patients are less likely to develop the disease or pass it on to others.

How Many People are Living With HIV?
As of 2016, the World health Organization estimates that well over 37 million people are HIV positive. Moreover, more than a million people die worldwide of HIV related causes each year. While HIV is treatable, most of these deaths occur in developing nations, where health resources are scarce. (According to the World Health Organization, over 95% of all HIV positive people live in developing countries.)
Opportunistic Infections and HIV/AIDS
By far, the greatest threat for those with HIV/AIDS is what are known as opportunistic infections, or OIs. Even with antivirals, HIV positive patients can be vulnerable to opportunistic infections.
In some cases, patients are not aware that they are HIV positive. In other cases, they are aware but untreated. In others still, treatment may lower, but not completely eliminate enough of the live virus in their body, rendering them infectious and a weakened immune system.
When HIV positive individuals are infected with certain opportunistic infections, they are considered to have crossed the threshold from being HIV positive to having developed AIDS, no matter how many T cells they have.
A person is also considered to have developed AIDS if their T cell numbers drop below 200. (The normal range for T cells is between 500 and 1,500.)
Common Opportunistic Infections for HIV/AIDS Include:
• Invasive Cervical Cancer
• Pneumocystis cariniipneumonia (PCP)
• Recurrent Pneumonia
• Recurrent Salmonella septicemia
• Progressive multifocal leukoencephalopathy
• Toxoplasmosis of the brain
• Wasting Syndrome related to HIV
• Mycobacterium avium complex (MAC)
What are the signs and symptoms of HIV?
The symptoms of an HIV infection can vary widely, depending on the stage of the disease. Many HIV positive people are not aware that they are infected. They may or may not, experience flu-like symptoms which can easily be missed or mistaken for other kinds of infections in the first few weeks after they are infected.
Early symptoms can occur within two weeks to two months of infection. It should be noted, many of these symptoms can be caused by other common health conditions and illnesses. The only way to determine if someone is HIV positive, or infected with HIV, is to be tested. HIV can also be transmitted from mother to child during pregnancy, labor or birth.
Early Symptoms of HIV Infection can Include:
• Fatigue (tiredness)
• Swollen lymph glands
• Sore throat
• Skin rashes
• Joint and or muscle pain and other flu-like symptoms
• Ulcers in the mouth
• Ulcers on the genitals
• Night sweats
How is HIV Transmitted?
HIV can be transmitted by sharing contaminated needles, having anal, vaginal or oral sex with someone who is HIV positive, even if they do not have symptoms of the disease.
What are the Risk Factors for HIV?
HIV can affect anyone, regardless of their race, gender, or sexual orientation. Risk factors for HIV include:
• Having unprotected sex (vaginal, oral or anal) with a single or multiple partners
• Sharing contaminated needles or other injecting equipment for drug use
• Having another form of sexually transmitted disease (STD)
• Receiving unsafe blood products or non-sterile piercings or tattoos
• Accidental needle sticks (usually among healthcare workers)
Is HIV a Disease that Only Affects People in the LGBT Community?
No. Anyone, regardless of sexual orientation, socioeconomic level, race or ethnicity can become infected with HIV.
How is HIV Diagnosed?
HIV testing requires a blood test. There is no one single blood test that can detect HIV, but HIV tests can be done in combination to provide a diagnosis. When properly performed, HIV testing can determine if someone is infected with a high degree of accuracy.
How Can I Help Prevent the Spread of HIV?
• Always use safe sex practices such as using a condom
• Do not share needles
• Get HIV testing and preventative counseling
• Use prescribed antiviral medications (Truvada)
