Explain the direct and indirect cost with this statement below:
"The direct costs focus on the consumption of resources in the treatment of illness and injury and, generally, refer to those items for which some form of payment has been made, including medical care expenses such as hospitalization, outpatient and physician visits, long-term care, drugs, medical care, formal caregiving, equipment, etc. The indirect costs focus on those resources which are foregone due to the illness or injury and thus cannot be used for other purposes but involve no direct payment to service providers. These include labour supply effects such as the value of lost production due to absenteeism or presenteeism (working but not at full productivity) resulting from disability or premature mortality, or any type of caregiving without a formal payment. Together these costs give us information on the magnitude of the resource use related to the illness or injury. While this information is an important consideration for planning purposes, it does not present the entire burden associated with illness."
