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.
Officials with the New Mexico Department of Health announced in a Feb. 20 news release that a San Juan County man had contracted the state’s first case of hantavirus pulmonary syndrome this year.
The analysis of the first 100 U.S. cases identified showed that the disease was distributed in 21 states and had gone unrecognized since at least 1959. [4] HPS outbreaks were seen between 1950-1953 during the Korean War, as more than 3,000 United Nations soldiers fell ill with Korean hemorrhagic fever , a hantavirus that sees hundreds of cases ...
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]
