Although the true extent of economic damage is difficult to measure, the World Bank Group has estimated the GDP losses for the three countries to be approximately $2.2 billion ($240 million for Liberia, $535 for Guinea, and $1.4 billion for Sierra Leone).[4445] The amounts given above are related to specific interventions, but the total economic Ebola impact (not simply money spent, but all opportunities lost) will likely range from $3.8 billion to $32.6 billion, including factors such as investor aversion and interruptions to mining operations.[4647]
