MOMENTUM Country and Global Leadership collaborated with the Uganda Ministry of Health to develop a national “Investment Case for Integrated Community Case Management (iCCM) of Childhood Illnesses in Uganda.” The Investment Case provides the Government of Uganda and development partners with clear financing requirements and impact projection justifying continued investments to ensure institutionalization of sustainable, accessible, and equitable iCCM services at scale. Using the Community Health Planning and Costing Tool (CHPCT 2.0), this investment case costs the scale-up of iCCM over a five-year period and identifies a resource mobilization strategy to address a substantial total funding gap, estimated at US$0.8 per capita per year.
