Global Blindness course: An introduction to epidemiology
Channel: ICEH at LSHTM
Date: 12/04/2016

The word ‘epidemiology’ is of Greek origin: ‘Epi’, meaning ‘upon’, ‘Demos’, meaning ‘population’, and ‘Logos’, meaning ‘study’. This translates to ‘a study of that which is visited upon a population’. We now define epidemiology as the study of:
- distribution of health outcomes or disease in a population
- determinants that influence the occurrence of disease
- application, which provides direction for public health action.
In this video step, we consider each of these components more thoroughly and discover some commonly used epidemiological terminology. While you’re watching, consider how epidemiological data supports, or could support, eye care work.
