Explanation

Epidemiology is the study of epidemic diseases and how they spread in populations. It tracks patterns, causes, and effects of health and disease conditions. The prefix 'epi-' (upon/among) and 'demos' (people) combine to describe this population-level disease study. Dermis and epidermis refer to skin layers, not diseases of them.
