Data Sources and Update Policy
This tracker is an educational state-level visualization. Visitors should verify current public-health information with official CDC and local health department resources.
Primary reference links
The site links to CDC hantavirus and rodent-control resources as official references. State-level summaries are provided for educational map exploration and should be checked against current official sources before making health decisions.
Update cadence
The dataset is reviewed periodically and the current site update marker is shown on each page. This is not a live emergency-alert feed and should not be treated as real-time medical surveillance.
Known limitations
The tracker is state-level, not county-level or address-level. It may not include every historical or newly reported case, and it does not diagnose disease or confirm active local outbreaks.
Frequently Asked Questions
Is the tracker real-time?
No. It is an interactive educational tracker with a displayed update date, not a real-time public-health alert system.
Where should visitors verify urgent information?
Use CDC resources, state health departments, local public-health agencies, or a licensed clinician for current guidance.
