ABSTRACT:
Introduction. The full-scale armed aggression of the Russian Federation against Ukraine since February 2022 has generated systemic challenges for public health. According to the World Health Organization (WHO), more than 1000 attacks on healthcare facilities have been documented, resulting in significant disruptions to medical and preventive services. Over 11 million people have experienced internal displacement, exacerbating inequalities in access to healthcare. Estimates from the Ministry of Health of Ukraine (MoH) indicate a marked increase in excess mortality in 2022. Non-communicable diseases, particularly cardiovascular conditions, remain the leading causes of death, largely due to interruptions in treatment and prevention services. At the same time, international organizations report deterioration in mental health indicators and increased risks of infectious disease outbreaks. Methods. A conceptual analysis was conducted based on operational data from the All-Ukrainian Association of Public Health Specialists (UAPHS) covering 2023–2026, reports from the MoH, WHO, UNICEF, and publicly available materials and partner assessments. The role of NGOs in workforce development, advocacy, scientific communication, policy engagement, and international collaboration was assessed. Results. UAPHS serves as a national professional platform that brings together public health specialists and strengthens system capacity during wartime. Key areas of activity include continuous professional development, advocacy for immunization, prevention of non-communicable diseases, and mental health support, multisectoral engagement, and international partnerships (EUPHA, APHA). Implemented initiatives include the professional journal Public Health Accents, the online educational platform Academy for Professional Skills Development, participation in European Public Health Week, and academic partnerships for curriculum development. The use of digital solutions ensured continuity of professional training despite infrastructure disruptions. Conclusions. The experience of UAPHS demonstrates the critical role of NGOs in strengthening public health system resilience during war through workforce development, advocacy, and international solidarity. The lessons learned are relevant for global public health practice in crisis and conflict settings.
