MANILA, Philippines — The Philippines has recorded the highest estimated rate of new HIV infections among adolescents in Southeast Asia, marking a dramatic reversal from 25 years ago when the country was among the region’s least affected, newly released UNICEF data shows.
The estimated HIV incidence among Filipinos aged 15 to 19 reached 0.49 new infections per 1,000 uninfected adolescents in 2025, according to UNICEF’s latest epidemiological data for children and adolescents. That is equivalent to approximately 49 new infections per 100,000 uninfected adolescents in a year.
The figures highlight a troubling long-term trend: the Philippines’ estimated adolescent HIV incidence was below 0.01 per 1,000 in 2000, before rising to 0.10 in 2011, 0.25 in 2019 and 0.49 in 2025.
The data was analyzed by University of the Philippines Diliman associate professor and data scientist Dr. Rogelio Alicor Panao, who said the country’s trajectory stands in sharp contrast to several of its Southeast Asian neighbors.
“Twenty-five years ago, the Philippines was among the Southeast Asian countries least affected by HIV among adolescents. Today, it has the region’s highest estimated incidence,” Panao said.
A Reversal Few Expected
The contrast becomes even more striking when compared with countries that once faced substantially higher estimated adolescent HIV incidence.
Thailand’s estimated rate declined from 1.80 per 1,000 in 2000 to 0.29 in 2025, while Myanmar’s fell from 1.26 to 0.43. Cambodia also reduced its estimated rate from 0.68 to 0.16, according to the UNICEF-based analysis.
The comparison offers both a warning and a message of hope: rising HIV infections among young people are not inevitable, and prevention strategies can change the course of an epidemic when they effectively reach those most at risk.
The Wider HIV Crisis Is Already Raising Alarm
The adolescent figures come as the Philippines continues to grapple with one of the fastest-growing HIV epidemics in the Asia-Pacific region.
In June 2025, the Department of Health, supported by UNAIDS and the World Health Organization, called for urgent and coordinated action as new HIV diagnoses surged. UNAIDS and WHO reported that new HIV cases in the Philippines rose from about 4,400 in 2010 to 29,600 in 2024, while an estimated 252,800 Filipinos were living with HIV in 2025.
Young Filipinos are at the center of the concern. In the first quarter of 2025, around one-third of newly diagnosed HIV cases involved people aged 15 to 24, according to the joint UNAIDS-WHO assessment.
More recent surveillance data also underscores that young people remain heavily affected. Of the 4,277 newly reported HIV cases during the fourth quarter of 2025, people aged 15 to 24 accounted for 32 percent, according to Department of Health data reported by GMA News.
Prevention Is Available—But Access Remains Critical
Health experts stress that HIV is preventable and treatable. Effective prevention tools include condoms, HIV testing, pre-exposure prophylaxis (PrEP), post-exposure treatment when appropriate, and HIV self-testing, alongside accurate, age-appropriate education and accessible health services.
The Philippines has already taken important policy steps. Under the Philippine HIV and AIDS Policy Act, the age of consent for voluntary HIV testing was lowered to 15, while PrEP has been included in the Philippine National Formulary.
But policy alone does not guarantee access.
Panao said prevention efforts must reach young people where they are—both physically and online—and called for stronger access to confidential testing, condoms, PrEP and HIV self-testing, as well as comprehensive sexuality education.
The challenge is particularly urgent because global evidence shows that adolescents can face significant barriers to testing and prevention. UNICEF notes that HIV prevention must be tailored to young people’s realities, with services that are accessible, trusted and responsive to the communities they serve.
The Warning—and the Opportunity
The Philippines’ rise from one of the lowest estimated adolescent HIV incidence rates in Southeast Asia to the highest is a stark warning that the country’s HIV response must move faster, particularly for younger populations.
But the experience of neighboring countries also offers a critical lesson.
High HIV incidence can be brought down. Thailand, Cambodia and other countries have demonstrated that sustained prevention, testing, treatment and community-based responses can change the trajectory of an epidemic.
For the Philippines, the question is no longer whether the warning signs are visible.
The data is already here. The real challenge is whether prevention and health services can reach young Filipinos before the next generation of statistics becomes even harder to reverse.
