Geography
Hantaviruses are found worldwide in rodent reservoirs, but the viruses, syndromes, and public health reporting systems differ by region.
In the Americas, New World hantaviruses can cause hantavirus pulmonary or cardiopulmonary syndrome.
In Europe and Asia, hantaviruses are commonly discussed in relation to hemorrhagic fever with renal syndrome.
Local public health agencies are the right source for local case reporting and exposure investigations.
CDC surveillance began after the 1993 Four Corners outbreak. Public U.S. case geography is state-level, and most reported cases have occurred west of the Mississippi River.
ECDC reports EU/EEA orthohantavirus surveillance, often involving Puumala virus and bank voles. PAHO/WHO and WHO provide regional and outbreak context for the Americas, including Andes virus in South America.
