World AIDS Day 2025: Renewing Global and National Commitment to Ending HIV as a Public Health Threat

Every year on 1 December, nations around the world commemorate World AIDS Day, reflecting on the profound human, social and economic impact of HIV and renewing commitments to confront one of the world’s longest-running health emergencies. As the world enters 2025, the message is clear: while extraordinary progress has been made, HIV remains an unfinished agenda. Millions continue to live with the virus, new infections occur daily, and inequalities still hinder access to prevention, testing and treatment services.

The World Health Organization (WHO) reports that HIV has already claimed 44.1 million lives since the beginning of the epidemic, and transmission continues in every region. Global efforts, strongly aligned with the Sustainable Development Goals (SDG 3.3), aim to end AIDS as a public health threat by 2030. But this target demands strengthened public health systems, equitable access to care, and greater awareness in every community.

1. The Global HIV Situation in 2025

The epidemic continues despite progress

As of the end of 2024, the WHO estimates that 40.8 million people are living with HIV worldwide. Of this global burden, approximately 65 per cent — over 26 million people — live in the African Region, highlighting persistent structural inequalities across continents.

Despite decades of progress, the epidemic continues:

• 1.3 million people acquired HIV in 2024

• 630,000 people died from HIV-related causes in 2024

• HIV remains present in every country worldwide

These figures remind us that the epidemic is far from over.

Global treatment cascade: progress but gaps remain

In 2024, the world achieved the following:

• 87 per cent of all people living with HIV knew their status

• 77 per cent of all PLHIV were receiving antiretroviral therapy (ART)

• 73 per cent

• Per cent – achieved viral suppression

These numbers fall short of the 2025 global targets, known as the 95-95-95 goals, which aim for:

1. 95 per cent of PLHIV know their status

2. 95 per cent of those diagnosed to be on ART

3. 95 per cent of those on ART to achieve viral suppression

Viral suppression is critical because a person whose viral load is undetectable cannot transmit HIV sexually—a scientific breakthrough known globally as U=U (Undetectable = Untransmittable).

2. Myanmar’s HIV Situation: Latest Data (2023–2025)

Despite operational challenges, Myanmar has maintained significant progress in HIV diagnosis and treatment coverage.

Estimated national HIV burden

Based on UNAIDS, AIDS Data Hub, UN Myanmar, and ICAP (Columbia University), the latest consolidated estimates indicate:

• Estimated people living with HIV in Myanmar (PLHIV): 240,000–280,000

• Children living with HIV (≤15 years): 11,000

• New HIV infections per year: 11,000

• Annual AIDS-related deaths:

Estimated 7,000–8,000 (modelled estimates)

• ART coverage:

208,480 individuals — approximately 74 per cent of PLHIV

Nature of the epidemic in Myanmar

Myanmar’s epidemic remains concentrated, with higher infection rates seen among:

• people who inject drugs

• men who have sex with men

• sex workers and their clients

• transgender people

These populations require intensified prevention services, stigma-free healthcare, and consistent treatment access.

Service delivery challenges

Ongoing social, economic and geographic barriers, including population mobility, funding gaps and limited access in conflict-affected regions, can hinder testing, care and outreach coverage. Nonetheless, national and partner organizations continue working to sustain essential HIV services.

3. Understanding HIV and AIDS

HIV: The virus that attacks the immune system

Human immunodeficiency virus (HIV) weakens the body’s natural defences by attacking CD4

Cells – white blood cells are essential for fighting infections.

AIDS: The most advanced stage

Untreated HIV can eventually develop into acquired immunodeficiency syndrome (AIDS), a life-threatening condition marked by severe infections and certain cancers.

Advanced HIV Disease (AHD)

WHO defines AHD as:

• CD4 count <200 cells/mm³, or

• Presence of WHO Stage 3 or 4 clinical events

All children under five living with HIV are classified as having AHD due to their vulnerable immune systems.

4. How HIV Is—and Is NOT—Transmitted

HIV is transmitted through:

• blood

• semen

• vaginal fluids

• rectal fluids

• breast milk

Transmission occurs through:

• unprotected sex

• sharing injection equipment

• mother-to-child transmission during pregnancy, delivery or breastfeeding

• transfusion of contaminated blood

• medical procedures using unsterile equipment

HIV is NOT transmitted by:

• kissing or hugging

• shaking hands

• sharing food, cups, clothes or toilets

• mosquitoes or insects

• casual social contact

Dispelling myths helps reduce stigma and improves testing uptake.

5. Symptoms Across HIV Stages

Early infection (first weeks):

• fever

• headache

• sore throat

• rash

Some experience no symptoms, which makes testing essential.

Chronic infection:

• weight loss

• swollen lymph nodes

• fever

• diarrhoea

• persistent cough

Advanced infection / AIDS:

• tuberculosis (TB)

• cryptococcal meningitis

• severe bacterial infections

• cancers (lymphomas, Kaposi’s sarcoma)

HIV can worsen hepatitis B, hepatitis C and mpox outcomes.

6. HIV Prevention: Tools That Work

HIV is preventable. Proven strategies include:

• consistent condom use

• regular HIV and STI testing

• voluntary medical male circumcision

• harm-reduction services (needle–syringe programmes, opioid substitution therapy)

Pre-Exposure Prophylaxis (PrEP)

WHO-recommended PrEP options include:

• oral tenofovir (TDF)-based PrEP

• dipivefrine vaginal ring

• long-acting injectable cabotegravir

• long-acting injectable lenacapavir (recently FDA-approved)

Post-Exposure Prophylaxis (PEP)

PEP must begin within 72 hours after potential exposure.

Preventing mother-to-child transmission

With ART, the risk can drop to below one per cent.

7. HIV Diagnosis: Rapid, Accurate and Accessible

• Rapid diagnostic tests give same-day results

• HIV self-testing expands privacy and accessibility

• Confirmatory testing ensures accuracy

• Babies under 18 months require virological testing, not antibody tests

Correct diagnosis enables early treatment, which improves long-term health outcomes.

8. Treatment: HIV as a Manageable Chronic Illness

No cure – but highly effective treatment

Antiretroviral therapy (ART):

• suppresses the virus

• strengthens the immune system

• prevents HIV transmission to partners

• transforms HIV into a manageable chronic condition

ART must be taken daily for life, but new long-acting injectables may change future treatment patterns.

Pregnant women

Early ART protects both mother and child and prevents transmission.

Addressing Advanced HIV Disease

WHO supports countries to deliver essential AHD care, including rapid diagnosis, opportunistic infection screening and new therapeutic options.

9. The Road to 2030: WHO’s Strategic Response

WHO’s Global Health Sector Strategies (GHSS) 2022–2030 outline how countries can end AIDS, viral hepatitis and sexually transmitted infections by 2030. Key priorities include:

• universal health coverage

• equity-centred approaches

• reaching the most vulnerable populations

• strengthening community-led responses

• integrating HIV services into primary healthcare

10. Why World AIDS Day 2025 Matters for Myanmar and the World

The world has the tools to defeat HIV — but gaps in access, awareness and equity persist. For Myanmar:

• 240,000–280,000 people live with HIV

• ~208,480 people receive ART, a major public health achievement

• community support and awareness remain essential

Globally, ending AIDS by 2030 is still possible — but only with sustained commitment.

Empathy, accurate information and inclusive public health strategies can eliminate stigma, support those living with HIV, and protect future generations.
