Economic costs in epidemiology refer to the financial burden incurred due to the presence of a disease or health condition. These costs can be categorized into direct, indirect, and intangible costs. Direct costs include medical expenses such as hospital stays, medications, and medical procedures. Indirect costs pertain to productivity losses, such as missed workdays or reduced work capacity. Intangible costs involve pain, suffering, and reduced quality of life, which are harder to quantify but equally significant.
