Rising HIV Infections Among Young Adults in Thailand and Global Trends

Thailand is experiencing a concerning rise in HIV infections, particularly among young adults, prompting renewed prevention efforts. While significant progress has been made in combating HIV/AIDS since the peak of the epidemic in the late 20th century, recent data indicates a demand for increased awareness and preventative measures, especially regarding safe sexual practices. This trend mirrors a global pattern, with similar increases observed in other countries like France.

HIV Statistics in Thailand (2025)

In 2025, Thailand recorded 13,357 new HIV diagnoses, bringing the total number of people living with HIV to 547,556 [AHF Thailand]. A significant proportion of these new cases – 35% – were individuals aged 15 to 24. The vast majority, 96.4%, of new infections were linked to unprotected sex [AHF Thailand], highlighting the critical need for comprehensive sex education and access to preventative resources.

AHF Thailand’s Prevention Campaign

The AIDS Healthcare Foundation (AHF) Thailand has launched a prevention campaign, dubbed ‘Employ It,’ in response to the government data revealing that young people account for more than a third of new HIV infections [AHF Thailand]. This campaign aims to promote condom use and safer sexual practices among this vulnerable population.

Regional Focus: Chiang Mai

Chiang Mai province provides a localized example of the challenges Thailand faces. In 2024, 731 new HIV cases were recorded in Chiang Mai, bringing the total number of people living with HIV in the province to 22,387 [AHF Thailand]. Fortunately, 21,576 individuals in Chiang Mai have access to antiretroviral therapy (ART) through the public health system [AHF Thailand].

Global Trends: France

The increase in HIV infections among young adults is not unique to Thailand. France has also observed a similar trend. Between 2014 and 2023, diagnoses of HIV seropositivity increased by 41% in the 15-24 age group, while cases decreased by 15% among adults [AHF Thailand]. Despite this, HIV screenings are increasing, with 8.5 million tests conducted in 2024, a 13% rise from the previous year, largely due to the availability of free, prescription-free tests. However, concerns remain regarding late diagnoses, with 43% of infections reported at a late stage, including 27% at an advanced stage [AHF Thailand].

HIV Testing Accessibility in Thailand

Thailand offers accessible HIV testing, with citizens able to receive a free test twice a year through national health coverage [AHF Thailand].

The Role of the Thai National AIDS Foundation (TNAF)

Established in 1999, the Thai National AIDS Foundation (TNAF) plays a crucial role in raising funds and resources to support HIV/AIDS prevention and care programs throughout Thailand [ThaiAIDS]. TNAF collaborates with governmental and non-governmental organizations, as well as private businesses, to support individuals affected by HIV/AIDS and reduce the further spread of the disease [ThaiAIDS]. The foundation focuses on vulnerable populations, including children, women, the elderly and hill-tribe communities [ThaiAIDS].
