Prognosis for HPS is often poor. The case fatality rate of HPS ranges from 30% to 60%. [2] [4] [21] [27] Death usually occurs 2–10 days after the onset of illness [10] and occurs suddenly during the cardiopulmonary phase of illness. [2] [3] Andes virus infection has a case fatality rate of about 40%, and Sin Nombre virus a case fatality rate ...
There have been seven confirmed cases and three deaths in the past six months, according to a recent health alert. Most cases of hantavirus are reported in the Western and Southwestern United States.
Transmission electron micrograph of the Sin Nombre virus, the virus responsible for the outbreak. The spherical particles are virus bodies (virions). The 1993 Four Corners hantavirus outbreak was a disease outbreak caused by a hantavirus that occurred in the Four Corners region of the US states in Arizona, Colorado, and New Mexico.

[4] [7] Person-to-person transmission reportedly occurs mainly within families or when engaging in close activities with an infected person during the prodromal disease phase. [7] A 2021 systematic review, however, found these claims not to be supported by sufficient evidence and cited flawed methodology in research on Andes virus outbreaks.
Hantavirus infections are associated with high fever, lung edema, and pulmonary failure. The mortality rate varies significantly depending on the form, being up to 50% in New World hantaviruses (the Americas), up to 15% in Old World hantaviruses (Asia and Europe), and as little as 0.1% in Puumala virus (mostly Scandinavia).

The case fatality rate from PUUV infection is low, at 0.08–0.4%, [11] and nearly everyone recovers fully without long term consequences. [17] Death usually only occurs among the elderly. [14] On rare occasions, individual cases and small clusters of hantavirus pulmonary syndrome have been observed in Europe [20] and in Turkey. [21]
