Is this a live hantavirus case tracker?
No. Hantavirus Maps is a source-linked educational map and reviewed snapshot. It does not show live infections, patient locations, or exact exposure locations.
FAQ
Hantavirus Map FAQ
Plain-language answers for reading the map, source markers, official alerts, reservoir ecology, and the limits of this educational snapshot.
What do the numbers and markers mean?
Markers summarize reviewed source records. They may represent a state-level case summary, an official public health alert, or reservoir ecology. They are not confirmed local case counts at a household, cabin, workplace, or county.
Does CDC publish public county-level hantavirus case locations?
CDC publishes public U.S. hantavirus geography by state and says county-level data cannot be provided publicly. This site follows that limitation and does not infer county risk.
Does a reservoir region mean people are getting sick there?
No. Reservoir distribution is ecological evidence. It does not prove that specific animals are infected, that human cases are occurring, or that a specific site is unsafe.
What sources does the map use?
The MVP prioritizes official and source-linked public health information such as CDC, WHO, PAHO/WHO, ECDC, and state health department sources. The source registry explains how records are selected and limited.
Why include official alerts if they are not complete surveillance?
Official alerts can explain notable public health events and agency responses, but they are not complete case databases. The site labels alerts separately from historical case summaries and reservoir ecology.
Can I use this map to decide whether a place is safe?
No. The map cannot determine exact risk for a home, campsite, cabin, workplace, county, or trip. Local public health authorities, clinicians, occupational safety teams, and pest-control professionals are the right sources for site-specific decisions.
What should I do if I feel sick after rodent exposure?
Contact a healthcare provider or public health authority and describe the exposure. Trouble breathing or rapidly worsening illness needs urgent medical attention.
