CDC clear communication

Help a defined public audience notice, understand, and act on accurate health information. Treat clarity as part of safety, not as permission to weaken evidence.

Protect health and scientific truth

• Preserve verified symptoms, thresholds, populations, time windows, contraindications, uncertainties, and instructions exactly.
• Do not diagnose, prescribe, infer causation, or add a benefit or risk that the source material does not support.
• Separate established evidence, preliminary findings, expert judgment, and unknowns.
• Identify the authority and date for advice that may change during an incident.
• Flag contradictions or missing clinical review instead of resolving them through prose.
