Sustainable practices have become critical in addressing the growing threat of emerging and re-emerging tropical diseases. This chapter focuses on how integrating sustainability into healthcare systems can strengthen disease control, improve resilience, and foster long-term solutions across diverse tropical regions. It examines the environmental, economic, and social factors (such as climate change, urbanization, and weak infrastructure) that exacerbate tropical disease outbreaks. Using detailed case studies on diseases like Zika virus, dengue fever, Ebola virus disease, and leishmaniasis, the text highlights successful sustainable interventions including eco-friendly vector control, community-based healthcare delivery, sustainable immunization programs, and low-cost diagnostic innovations. Cross-cutting discussions reveal how technology, social equity, and ecological protection intersect to shape enduring public health outcomes. Furthermore, the work explicitly links sustainable tropical disease management to key Sustainable Development Goals (SDGs), notably good health (SDG 3), clean water and sanitation (SDG 6), climate action (SDG 13), and life on land (SDG 15). It argues that resilience, environmental consciousness, and equity must be at the heart of disease management strategies to safeguard global health systems against future crises. The chapters demonstrate how integrated, sustainability-centered approaches enhance outbreak preparedness and long-term health security by using examples from Ebola virus disease, yellow fever, monkeypox, and Marburg virus. Ultimately, this work calls for a transformative shift—aligning emergency responses with sustainable system-building, leveraging technology, community ownership, and climate resilience to drive global health progress and sustainable development.
