Epidemiology deals with the incidence, distribution, and possible control of diseases and other factors relating to health. Epidemiology is the study and analysis of the patterns, causes, and effects of health and disease conditions in defined populations. It is the cornerstone of public health, and shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare. Epidemiologists are concerned with study design, collection and statistical analysis of data, amend interpretation and dissemination of results. Evolutionary epidemiology spans a broader spectrum of host-parasite relationships. In tropical and sub-tropical regions, the disease usually occurs year-round, although seasonal peaks of increased activity may be observed.
