Turks and Caicos Islands’ WHO certification offers three critical insights for public health systems worldwide. First, the achievement demonstrates that eliminating mother-to-child transmission of both HIV and hepatitis B is an attainable goal regardless of geographic or economic constraints. Second, the success was built on comprehensive antenatal screening and treatment programs, proving that early detection and intervention during pregnancy are key to preventing transmission. Third, the certification shows that small island developing states—often assumed to have limited resources—can meet and maintain global health standards when systematic approaches are implemented. Health systems seeking to achieve similar results should prioritize universal antenatal screening, accessible antiretroviral therapy, and sustained monitoring protocols. The Caribbean region’s three certified territories provide evidence that this pathway works, offering practical models for other nations committed to eliminating preventable mother-to-child transmission.
