World AIDS Day 2025

World AIDS Day is acknowledged every year on the first of December to raise awareness, show support for people living with HIV, and unite in the fight against HIV. World AIDS day originated at the 1988 World Summit of Ministers of Health on Programs for AIDS Prevention. Since then, every year United Nations agencies, governments, and communities join forces to campaign around specific themes related to AIDS. 

Viral load testing is used to diagnose acute HIV infection by measuring the amount of HIV in a patient’s blood sample. Viral load testing is also used to give health care providers treatment guidance and monitor patient response to antiretroviral therapy (ART). Results are reported as the number of copies of HIV RNA per milliliter of blood. Examples of different tests include quantitative branched DNA (bDNA), reverse transcriptase-polymerase chain reaction (RT-PCR), and qualitative transcription-mediated amplification.

This year's campaign urges world leaders, advocates, and health experts to continue to deliver on the shared commitment of ending new infections by 2030. However, structural inequalities are threatening this goal. Gaps in access to prevention, testing, treatment, and education continue to fall along lines of race, gender, income, and geography, leaving the most vulnerable communities at the greatest risk. To truly achieve an AIDS-free future, efforts must prioritize equity, strengthen health systems, and ensure that lifesaving resources reach every person, in every setting, without stigma or barriers.

CLSI provides international outreach services and hands-on support to laboratories throughout the world through our Global Health Partnerships program. Part of this support is providing quality management system training to laboratorians who perform viral load testing in resource-constrained countries throughout the world.
