Emerging infectious diseases present a significant challenge to healthcare systems with their need for a rapid response and reallocation of resources. This paper explores the implementation of the Practical Approach to Care Kit (PACK) programme in Florianópolis, Brazil as a strategic tool for reinforcing primary healthcare (PHC) responses to emergent communicable diseases. With its focus on enhancing PHC delivery in resource-limited settings, PACK provides a flexible, evidence-based framework that integrates into local health systems. The paper describes experiences adapting PACK to provide rapid responses to outbreaks of Zika, leishmaniasis, COVID-19, Mpox and dengue in primary care between 2014 and 2023. Key features of PACK, including its flexibility to incorporate new clinical content, responsive implementation strategy and health system strengthening approach, are highlighted. The paper emphasises how PACK supported responses to specific disease outbreaks and helped maintain mainstream PHC delivery, preventing the system from becoming condition-centric during crises. We describe the limitations of the PACK approach in an outbreak scenario, the challenges experienced and efforts to tackle these. The lessons learnt from Florianópolis underscore the adaptability and relevance of comprehensive primary care approaches like PACK in supporting PHC professionals and local health systems to navigate emerging health challenges.
