Why is this labeled emerging instead of official?

Emerging means the report comes from corroborated secondary sources or an early agency notice that may still be revised. Official means the notice comes directly from an established government health authority.

Should I change my behavior based on this page alone?

Use this page to find the original agency notice. Follow your doctor and local health department for personal health decisions.

What does "official" mean on OutbreakThreat?

Official alerts come directly from a government health agency like WHO, CDC, FDA, or a state health department. We link to the original notice so you can read the full text and context.

What is the difference between an outbreak alert and a confirmed outbreak?

An alert on OutbreakThreat is a dated notice from an agency or reputable source. It might be an investigation update, a health advisory, or a surveillance report. It is not the same as a final case count or an officially declared outbreak. Agencies refine their wording as investigations continue.

How often is outbreak data updated?

We check our source agencies multiple times per day. New notices typically appear on OutbreakThreat within hours. Our editorial summaries are reviewed during business hours (Central Time).

Can I get alerts for my home, school, or business?

Yes. Paid plans let you save locations with a radius and receive email when a new agency notice matches your area and disease preferences. The map and alert index are always free to browse.

What this means

This page summarizes a public health notice with a link to the original source. It is not a diagnosis and not guidance for your personal medical decisions. Use it to decide whether to read the source in full or check local guidance.

Why we're watching this

We include items when a credible agency or source posts a dated notice that fits our geography and disease categories. Tiers describe the directness of the source (official agency vs. emerging corroboration).

What would make this more serious

Watch for updated case counts, wider geography, stronger laboratory confirmation, or changes in official travel or clinical guidance - all of which should appear on the linked source first.

What this does NOT mean

This page is not proof of an outbreak at your address, not a travel ban, and not a substitute for your clinician or health department. A map pin can be country- or region-level when that is all the agency stated - we label broad geography when the notice leaves location ambiguous.

Prevention context (general)

Travel, occupational, and clinical prevention measures are published by official agencies; we aggregate links and summaries only.
