Editorial policy

OutbreakThreat publishes outbreak signals and health briefs that aggregate public information from official agencies and reputable sources. This editorial policy explains how we select, verify, and present that information. Our goal is to help readers find verifiable outbreak notices quickly - not to replace professional medical judgment or official public-health guidance.

Source selection

We prioritize sources in this order:

1. Official government and international health agencies (WHO, CDC, FDA, ECDC, PAHO)
2. State and local public health departments with public notice portals
3. University epidemiology programs and peer-reviewed surveillance reports
4. Reputable secondary synthesis from established health media, when primary sources are cited

We do not publish signals from anonymous social media posts, unsourced blogs, or outlets with a history of health misinformation. Low-confidence or single-source items may appear as Watch-tier signals, which are hidden from default browsing and never used for subscriber email alerts.

How we write summaries

• Every published brief must cite at least one verifiable source URL that readers can open to confirm the underlying claim.
• We use plain English and avoid sensational language. Terms like "outbreak," "alert," and "signal" reflect what agencies have already published - not our own risk assessment.
• Geographic claims are attributed to the publisher's wording. If an agency names a county, we use that county; we do not infer broader or narrower geography.
• Medical claims (symptoms, prevention, treatment) are paraphrased from agency guidance with a source link. We do not offer original clinical advice.

Credibility tiers

• Official - sourced from a government agency or established international health body. These signals appear in default browsing and may trigger email alerts.
• Emerging - supported by reputable secondary reporting or corroborated by multiple sources, but official confirmation may still be pending.
• Watch - weakly verified or single-source. Hidden from default browsing and excluded from email alerts unless an administrator explicitly enables them.

Updates and corrections

When an agency updates or retracts a notice, we update our summary accordingly and note the revision date. If we discover an error in our own summary - geographic attribution, disease identification, or source link - we correct it promptly and note the change at the top of the affected brief.

Independence and advertising

OutbreakThreat is editorially independent. Advertising revenue does not influence which signals are published, which diseases are tracked, or how summaries are written. Ad placements are visually labeled and separated from editorial content.
