Introduction to Epidemiology
Epidemiology is the study of how diseases affect the health and illness of populations. It involves the investigation of the distribution, patterns, and determinants of health and disease conditions in defined populations. This field is essential for public health as it guides policymaking and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare.Key Resources for Epidemiologists
Several resources are available to aid epidemiologists in their research and practice. These resources range from databases and software to professional organizations and journals.Databases and Data Repositories
Access to accurate and comprehensive data is crucial for epidemiological research. Some of the most widely used databases include: CDC - Offers a wealth of data on various diseases, conditions, and public health issues.
WHO - Provides global health statistics and information on a wide range of health topics.
NIH - Includes numerous datasets related to health and disease research.
SEER - A comprehensive source of cancer statistics in the United States.
