This makes the Maldives the first country in the world to achieve 'triple elimination', a WHO statement said.
"The Maldives has shown that with strong political will and sustained investment in maternal and child health, elimination of mother-to-child transmission of these deadly diseases, and the suffering they bring, is possible," said WHO Director-General Dr Tedros Adhanom Ghebreyesus.
"This historic milestone provides hope and inspiration for countries everywhere working towards the same goal," he added.
Mother-to-child transmission leads to infections that affect millions worldwide.
In the WHO South-East Asia Region alone, provisional estimates indicate that in 2024, more than 23,000 pregnant women had syphilis and over 8000 infants were born with congenital syphilis.
About 25,000 HIV-positive pregnant women required treatment to prevent transmission to their babies, while hepatitis B continues to affect more than 42 million people in the region, the WHO statement said.
"The Maldives' achievement is a testament to its unwavering commitment towards universal health coverage, to provide quality and equitable care across its dispersed islands to all, including migrants," said Dr Catharina Boehme, Officer-in-Charge, WHO South-East Asia Regional Office.
"This landmark feat is an important step towards 'Healthy Beginnings, Hopeful Futures,' for improving maternal and newborn health by ending preventable deaths and prioritising long-term well-being.
"I congratulate Maldives and look forward to the country pioneering progress in many other areas, while sustaining these gains," Boehme added.
WHO said that over the years, the Maldives has built an integrated and comprehensive approach to maternal and child health. More than 95 per cent of pregnant women receive antenatal care, with nearly universal testing for HIV, syphilis and hepatitis B, the statement underlined.
