Something that is a universal truth is that HIV remains a significant global health challenge in 2024, with millions of people living with the virus worldwide. However, advances in medical research and public health initiatives have significantly improved the ways we can prevent and manage HIV.

Understanding these advancements is crucial for anyone looking to protect themselves and others from HIV. If you are invested in educating yourself on this topic then keep reading for six essential facts about HIV prevention, breaking down what you need to know to stay informed and safe.

1. Post-Exposure Prophylaxis (PEP) Can Be Taken Within 72 Hours Of Exposure

Imagine you've had a possible exposure to HIV, whether through unprotected sex (vaginal fluids, rectal fluids, any sexual fluids or intimate exchange of body fluids), a needlestick injury, or another high-risk situation, even other fluids like breast milk. In such cases, Post-Exposure Prophylaxis, or PEP, can be a vital tool in preventing HIV infection. PEP involves a combination of antiretroviral medications that work to stop the virus from taking hold in your body. However, timing is critical. For PEP to be effective, it must be started within 72 hours of the potential exposure, sooner is always better.

Once initiated, PEP is taken for 28 days, and it’s important to complete the full course for it to be effective. PEP is not a substitute for regular HIV prevention methods and is meant for emergency situations. If you think you’ve been exposed to HIV, seek medical advice from health care providers immediately, PEP is available at many emergency rooms, clinics, and some pharmacies. Early intervention can make a significant difference in preventing HIV and transmission risk.

2. Pre-Exposure Prophylaxis (PrEP) Can Prevent Future HIV Infection

While PEP is for emergency use after a potential HIV exposure, Pre-Exposure Prophylaxis, or PrEP, is designed to prevent HIV infection before it happens via sexual contact/body fluids or anything else. PrEP is a once-daily pill that, when taken consistently, can reduce the risk of acquiring HIV by up to 99% in people at high risk. This makes PrEP a powerful tool for prevention, particularly for individuals who might be regularly exposed to HIV through sexual activity or injection drug use.

PrEP is recommended for people who are HIV-negative and at ongoing risk of exposure, such as those with an HIV-positive partner, people who have multiple sexual partners, or those who inject drugs. It’s important to take PrEP as prescribed, missing doses can reduce its effectiveness. While PrEP is highly effective at HIV prevention, it does not protect against other sexually transmitted infections (STIs), so it should be used alongside other preventive measures, such as condoms or customized condoms that you might use.

If you’re considering PrEP as a prevention medicine, it’s necessary to have an open conversation with your healthcare provider or sexual health clinic about the treatment option. Regular check ups and lab tests are needed to ensure that PrEP is working effectively and that you’re staying healthy. PrEP is a long term commitment, but for many, it offers peace of mind and a powerful defense against HIV.

3. Condoms And Other Barrier Methods Provide Effective Protection During Sex

One of the most well-known and accessible methods of HIV prevention is the use of condoms and customized condoms. Condoms act as a barrier that prevents the exchange of bodily fluids during sex, thereby reducing the risk of transmitting HIV and other sexually transmitted infections like genital herpes and more. When used correctly and consistently, condoms are highly effective at preventing HIV transmission.

Both male and female condoms are available, and each provides a reliable means of protection when used properly. It's important to use a new condom every time you have sex, and to follow the instructions on the packaging to ensure it's applied correctly. Check the expiration date and make sure the condom is intact before use.

In addition to condoms, other barrier methods like dental dams can be used during oral sex to prevent the spread of HIV and STIs. Dental dams are thin squares of latex or polyurethane that act as a barrier during oral-vaginal or oral-anal contact. While less commonly discussed, these barriers are an important part of safer sex practices.

For people in relationships where one partner is HIV positive, consistent use of condoms can reduce risks of transmission to the HIV-negative partner. Combined with other prevention strategies, such as PrEP for the HIV-negative partner and antiretroviral therapy (ART) for the HIV-positive person, the risk of transmission can be minimized significantly.

4. Harm Reduction Programs Offer Sterile Drug Injection Equipment

For some drug users, sharing needles and other injection equipment is one of the most common ways HIV is transmitted. To address this and its associated level of risk, harm reduction programs provide access to sterile needles and syringes, which are crucial for preventing the spread of HIV and other bloodborne infections like hepatitis C.

These programs are often part of broader public health efforts that include education on safer injection practices, access to addiction treatment, and testing for HIV and other infections. By providing sterile intravenous drug injection equipment, harm reduction programs help to reduce the risk of HIV transmission among people who inject drugs.

Beyond just providing clean needles, many harm reduction programs also offer other essential services. This may include access to naloxone, a medication that can reverse opioid overdoses, as well as connections to healthcare and social services. Harm reduction is about meeting people where they are and providing them with the tools and resources they need to stay as healthy as possible, even if they continue to use drugs.

It's important to understand that harm reduction programs are not just about reducing the spread of HIV, they are about improving overall health and wellbeing. By offering non-judgmental support about risk of infection, these programs help individuals take steps toward better health outcomes, regardless of their circumstances with illegal drugs.

5. Regular HIV And STI Testing Is The Only Way To Know Your Status

The only way to know your HIV status with certainty is to get tested. Regular testing is a critical component of HIV prevention because it allows for early detection and prompt treatment, both of which are key to managing the virus and preventing its spread.

Human Immunodeficiency Virus rapid tests are quick, simple, and confidential. Depending on the test, results can be available within minutes, and there are many options available, including at-home testing kits, community health centers, and clinics. It’s generally recommended that people who are sexually active, particularly those with multiple partners, get tested for HIV at least once a year. More frequent testing may be necessary for individuals at higher risk, such as those with an HIV-positive partner, people who inject drugs, or men who have sex with men.

Alongside Immunodeficiency Syndrome testing, it’s also important to get tested for other sexually transmitted infections. Having an STI can increase the risk of acquiring or transmitting HIV, so knowing your status and seeking treatment for any infections is vital for both your health and the health of your partners.

Testing with healthcare professionals is not just about protecting yourself, it's also about protecting others. Knowing your status as a potentially infected person means you can take the necessary steps to prevent transmission, whether that involves starting treatment if you’re HIV positive or taking preventive measures if you’re HIV negative.

6. HIV Treatment Is Effective And Widely Available

If you are diagnosed with HIV, it's important to know that effective treatment beyond preventive treatment is available and can help you live a long, healthy life. Antiretroviral therapy (ART) is the standard treatment for HIV and involves taking a combination of medicines that work to control the virus in your body.

ART is highly effective at reducing the viral load, the amount of HIV in the blood, to undetectable levels. When a person’s viral load is undetectable, they cannot transmit HIV to others, a concept known as Undetectable = Untransmittable (U=U). This has been a groundbreaking development in both the treatment and prevention of HIV.

Starting ART as soon as possible after diagnosis is crucial, as it helps protect the immune system and reduces the risk of HIV-related illnesses. Regular medical appointments and adherence to the prescribed treatment regimen are essential to maintaining an undetectable viral load and staying healthy.

In addition to controlling the virus, ART also significantly reduces the risk of HIV transmission between sex partners, making it an important component of prevention strategies for HIV-positive individuals. It's important to remember that while ART is incredibly effective, it’s not a cure for HIV, ongoing treatment is necessary to keep the virus in check.
