Open disease hub (map + signals)What hantavirus is
Hantaviruses are a family of viruses spread mainly by infected rodents. In North America, some hantaviruses can cause hantavirus pulmonary syndrome (HPS), a severe respiratory illness that public health agencies investigate when cases are identified.
How it is thought to spread in affected settings
People may be exposed when virus-containing particles from rodent urine, droppings, or saliva are stirred into the air and breathed in, especially in closed spaces with rodent activity. This is why agencies emphasize rodent-proofing and safe cleanup—not because casual person-to-person spread is the main concern for these viruses in typical community settings.
Why local and regional signals can matter
When a jurisdiction posts an advisory, investigation update, or environmental risk notice, timing and geography in public reporting can lag behind what is happening on the ground. Tools that aggregate official and emerging notices can help residents see the same publisher-linked updates health departments intend to share—without replacing those departments.
How to use this information responsibly
Follow CDC and your state or local health department for prevention steps, especially if you live or work where rodents are common. This page does not claim that there is a current outbreak in any specific place unless a dated, source-linked OutbreakThreat signal is shown separately in the product.
