There is no debate that Caribbean countries have agreed to the critical importance of essential public health and essential public health functions and services. In fact, almost two decades ago, the Caribbean Commission on Health and Development (CCHD) stressed that: Any attempt to improve Caribbean health must begin with considering the resolving capacity of the health systems as a whole. All countries have health plans, but they are all bedeviled by the weaknesses in the information systems, the problems in managing the decentralization processes and the shortages of resources, physical, financial. and human. There is a critical need to examine the public health systems to correct the deficiencies in discharging the essential public health functions. Further, the Caribbean Cooperation in Health Phase III (CCH III) Regional Health Framework 2010 -2015 speaks to the need for Strengthened capacity of Member States to perform essential public health functions (EPHFs), that focus on three core areas: Assessment, Policy Development, and Assurance. This study examines the expenditure by Caribbean Community (CARICOM) countries on the delivery of EPHS, in the context of the global response to COVID-19. In particular, the study focuses on financing arrangements enacted to ensure the predictability of funding and the sustainability in the level and flow of funds over the medium and long terms to carry out essential public health functions in Barbados, Grenada, Jamaica and Trinidad and Tobago. The study also highlights the close, synergistic relationship between the Caribbean Public Health Agency (CARPHA) and its Member States.
