As the world observes HIV/AIDS Awareness Month, attention turns to education, stigma reduction, and empowering communities to confront the epidemic. Recognized each December in the United States, this annual observance honors those affected by HIV/AIDS while spotlighting medical advances, prevention strategies, and the work still required to achieve health equity for all.
Understanding HIV and AIDS

Human Immunodeficiency Virus (HIV) attacks the body’s immune system and is contracted through contact with certain bodily fluids—most commonly during unprotected sexual activity, sharing contaminated needles, blood transfusions with infected blood, or from mother to child during pregnancy, childbirth, or breastfeeding. Without treatment, HIV can progress to acquired immunodeficiency syndrome (AIDS), the most advanced stage of infection, leaving individuals vulnerable to life-threatening illnesses.
Decades of scientific progress, however, have transformed HIV from a near-certain death sentence in the 1980s into a manageable chronic condition for many. With proper care, people living with HIV can expect long healthy lives.
The Global and U.S. landscape
Globally, more than 40 million people were living with HIV in 2024, according to the World Health Organization (WHO). Approximately 630,000 deaths occurred from HIV-related illnesses—a significant decline from previous decades. Sub-Saharan Africa remains the most affected region, accounting for roughly 65% of all cases.
In the United States, an estimated 1.2 million people live with HIV, according to the Centers for Disease Control and Prevention (CDC). About 1 in 7 are unaware of their status, and roughly 33,000 new infections were reported in 2021.
Treatment: From crisis to control
Although HIV remains an incurable infection, Antiretroviral therapy (ART) has revolutionized HIV treatment. ART comes in both a pill and shot form and when taken consistently, is suppresses the virus to undetectable levels. This enables individuals to live full lives while eliminating the risk of sexual transmission—a principle known as Undetectable = Untransmittable (U=U). Early initiation of ART can reduce transmission risk significantly, according to the CDC.
Prevention: A multi-faceted strategy
Today’s prevention toolkit is more robust than ever:
- Pre-Exposure Prophylaxis (PrEP): A daily medication for HIV-negative individuals at higher risk, reducing transmission by over 99% when taken consistently.
- Post-Exposure Prophylaxis (PEP): Emergency medication that must be started within 72 hours after potential exposure.
- Condom Use and Routine Testing: Cornerstones of prevention and early diagnosis.
- Needle Exchange Programs (NEPs): Proven to reduce HIV transmission among people who inject drugs; approximately 80% of U.S. counties offer such programs.
- Education and Advocacy: Dispelling myths—such as HIV being spread through saliva or mosquitoes—is critical to reducing fear and discrimination.
Initiatives like the U.S. “Ending the HIV Epidemic: A Plan for America” aim to reduce new infections by 75% by 2025, primarily through expanded testing, PrEP access, and rapid treatment.
Ongoing Challenges
Despite remarkable progress, significant obstacles remain:
- Stigma and Discrimination: Fear of judgment, social rejection, or discrimination continues to discourage individuals from seeking HIV testing and treatment.
- Limited Health Literacy: Many people lack accurate education about how HIV is transmitted and the effective methods available for prevention.
- Low Risk Perception: Persistent stereotypes linking HIV risk to specific sexual orientations or behaviors lead some individuals to underestimate their personal risk.
- Limited Access to Healthcare: The cost of testing, medication, and ongoing treatment remains a significant barrier, particularly for individuals in low-income or underserved communities.
How to help
A diagnosis of HIV/AIDS can take a serious toll on mental health, increasing stress, depression, and anxiety. Studies show that about 20% of people with HIV report suicidal thoughts, nearly 10% have attempted suicide, and suicide rates are higher than in the general population. Risk is especially high in the first two years after diagnosis, driven by stigma, fear of disclosure, and social isolation. Mental health support and regular screening are critical components of HIV care.
Emotional support can make a meaningful difference. Listening without judgment, encouraging open conversation, and offering reassurance help reduce feelings of isolation. Simple acts, such as checking in regularly or accompanying someone to appointments, can provide comfort and stability.
Practical support is also essential. Assisting with transportation, medication reminders, or access to resources like food programs and financial aid eases daily burdens. Supporting adherence to antiretroviral therapy (ART) helps maintain health and prevents transmission.
Education and advocacy further strengthen support networks. Learning about HIV, addressing misconceptions, and challenging stigma empower both individuals and communities. Advocating for accessible healthcare and mental health services ensures that people living with HIV have the resources they need to thrive.
Turning awareness into action
HIV/AIDS Awareness Month is both a reflection of how far we have come, and a reminder of how much work remains. Scientific breakthroughs expanded prevention tools, and effective treatments have changed the course of the epidemic, yet progress has not been experienced equally by all communities. Every effort matters and this December, the focus is clear: Test. Treat. Empower.
