The Ministry of Health has completed the second week of its 2025 Rheumatic Heart Disease (RHD) screening in Vava’u, extending services to outer island schools.
The MAFU SAI program, aimed at early detection of RHD, conducted echocardiography screenings for primary students on the islands of Hunga, Ovaka, Matamaka, Noapapu, Taunga, Ofu, and Oloua. These efforts ensure that children in remote areas receive essential heart health assessments.

Following the Vava’u screenings, the program is set to continue in Tongatapu next week, with further details to be announced by the Ministry.
The Ministry of Health expressed gratitude to the Ministry of Education and Training, as well as parents, for facilitating access to schools across Vava’u. They also acknowledged the Australian Government, through the Department of Foreign Affairs and Trade (DFAT) and the Tonga Health Systems Support Program (THSSP), for their ongoing funding of the MAFU SAI initiative.
Established in 2008, the MAFU SAI program—meaning “Good Heart”—addresses the high prevalence of RHD among Tongan children. Annual screenings target Year 6 students, the age group most affected by the disease. Children diagnosed with RHD are registered and receive monthly penicillin prophylaxis at local health centres.
RHD remains a significant health concern in Tonga, contributing to the nation’s high rates of non-communicable diseases. The World Bank has approved a US$30 million grant to bolster Tonga’s healthcare system, particularly in combating such diseases and enhancing services in regions like Vava’u.
The MAFU SAI program exemplifies Tonga’s commitment to proactive healthcare, ensuring that even its most remote communities are not left behind.
