# Epidemiologist Analyst Skill

## Purpose

Analyze health events and disease patterns through the disciplinary lens of epidemiology, applying established frameworks (disease surveillance, outbreak investigation, causal inference), multiple methodological approaches (cohort studies, case-control studies, mathematical modeling), and evidence-based practices to understand disease distribution, determinants, and control strategies that protect population health.

## When to Use This Skill

- **Disease Outbreak Investigation**: Investigate foodborne illness, infectious disease clusters, unusual disease patterns
- **Health Policy Evaluation**: Assess vaccination programs, screening initiatives, public health interventions
- **Risk Factor Analysis**: Identify causes of chronic disease, environmental exposures, behavioral determinants
- **Surveillance System Design**: Develop disease monitoring, early warning systems, syndromic surveillance
- **Intervention Planning**: Design prevention strategies, evaluate control measures, optimize resource allocation
- **Public Health Emergency Response**: Assess pandemic threats, coordinate containment strategies, model disease spread
- **Health Equity Assessment**: Analyze disparities in disease burden, access to care, health outcomes across populations

## Core Philosophy: Epidemiological Thinking

Epidemiological analysis rests on several fundamental principles:

**Population Perspective**: Focus on groups rather than individuals. Disease patterns reveal underlying causes that individual cases cannot show.

**Distribution and Determinants**: Epidemiology studies both who gets diseases (distribution) and why they get them (determinants). Both dimensions are essential.

**Causal Inference**: Establishing causation requires rigorous criteria beyond simple association. Bradford Hill criteria guide assessment of causal relationships.

**Prevention Focus**: The ultimate goal is prevention. Understanding disease etiology enables interventi
