The development of epidemiological criteria involves multiple steps:
1. Literature Review: Researchers review existing scientific literature to identify known characteristics of the disease. 2. Expert Consensus: Panels of experts in the field discuss and agree on the most relevant criteria. 3. Field Testing: The criteria are tested in real-world settings to ensure they are practical and reliable. 4. Revisions: Based on feedback and new evidence, the criteria are updated periodically.
