ABSTRACT
BACKGROUND:
In 2024, Brazil experienced its largest dengue epidemic, with over 6.5 million cases, the highest global burden. Despite this, Brazil has become a leader in innovative and sustainable dengue control strategies. Leveraging its Universal Health System (SUS), the country implemented interventions that combined biological innovation, vaccination programs, and digital surveillance technologies. This study aims to analyze Brazil's integrated approach to identify replicable strategies for dengue control in universal health coverage settings.
METHODS:
The study examines Brazil's multi-faceted dengue control approach, implemented through public health infrastructure during 2024-2025. Three innovations were assessed: (1) the world's largest Wolbachia biofactory, producing 5 billion mosquitoes annually to protect 14 million people; (2) the incorporation of the dengue vaccine into SUS for high-burden municipalities; and (3) digital surveillance systems that integrate real-time data for epidemic prediction. Data sources included reports from the Brazilian Ministry of Health, PAHO surveillance data, and Fiocruz technical reports.
RESULTS:
The integrated approach demonstrated substantial impact. The Wolbachia program, which expanded from pilot cities to nationwide deployment, reduced dengue transmission by up to 77% in intervention areas. The vaccine rollout in 2024-2025 prioritized 521 high-burden municipalities, initially targeting 3.2 million adolescents. Digital surveillance facilitated early outbreak detection, reducing response time by 60%. Although Brazil reported the highest absolute case numbers in the Americas, a 70% reduction in cases was achieved in 2025 compared to 2024, alongside declining mortality rates. The universal health system ensured equitable access to these innovations across socioeconomic groups, illustrating that sustainable, technology-driven interventions can be implemented at scale within public health frameworks.
CONCLUSIONS:
Brazil's experience indicates that combining strategies within universal health coverage can transform dengue control. This model provides valuable lessons for global health equity, demonstrating that sustainable, nature-based solutions can be scaled through public health systems to effectively protect vulnerable populations.
