Chikungunya virus remains a persistent public health challenge in many tropical and subtropical regions, causing recurrent outbreaks and significant morbidity. This chapter explores sustainable approaches to building resilient healthcare systems that improve access, equity, and quality of diagnosis and care for chikungunya patients. Emphasizing the need for localized healthcare delivery models, it highlights community-based treatment centers, decentralized care systems, and the integration of digital health technologies to extend services to underserved populations. Preventative measures, including environmental management and public awareness campaigns, are presented as critical components for reducing vector populations and interrupting transmission cycles. The chapter also discusses the importance of embedding resilience within healthcare systems to adapt to fluctuating outbreak dynamics and resource constraints. Major strategies include strengthening healthcare infrastructure, workforce capacity building, supply chain optimization, and flexible service delivery. Sustainability is further supported by diversified financing models, multisectoral partnerships, and incorporation of chikungunya care into primary health frameworks to ensure long-term program viability. Challenges such as inequitable access, social determinants, and gaps in diagnostic and treatment capacity are examined, alongside opportunities offered by innovations in vector control, therapeutics, and community engagement. Policy recommendations underscore the need for cohesive governance, sustained funding, and inclusive stakeholder collaboration. Ultimately, this chapter advocates for a multifaceted, culturally sensitive approach that balances immediate clinical needs with broader social and environmental determinants. By fostering resilient and sustainable systems, it aims to improve health outcomes and reduce the chikungunya burden, offering a replicable model for managing emerging vector-borne diseases in resource-limited settings.
