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. The outbreak marked the discovery of hantaviruses in the Western Hemisphere that could cause disease and revealed the existence of a novel type of disease caused ...
From 1962 to 2022 there have been 157 recorded cases of the infection in United States, only 4 of those 157 individuals survived the disease. A combination of drugs have shown effectiveness in survivors. [11] Glanders, septicemic: Bacterial Untreated 95% The rate drops significantly to >50% with treatment. [12]
HPS has a much higher case fatality rate than HFRS, at 30–60%. For both HFRS and HPS, illness is the result of increased vascular permeability, decreased platelet count, and overreaction of the immune system. Individual hantavirus particles (virions) are usually spherical and vary at 70–350 nanometers in diameter.
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.
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 ...
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 ...
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).
