Hantavirus-positive rodents increased in the year after ENSO events, with higher infection rates in areas with dense vegetation. Human Cases of Hantavirus increase the year after an ENSO event, coinciding with elevated rodent populations. [6] Studies link ENSO events with a rise in human hantavirus cases, especially in the year following the ...
Arizona public health officials are warning that hantavirus, a virus spread by rodents to humans, is causing an increase in a potentially fatal lung syndrome. Arizona officials warning about ...
Hantavirus pulmonary syndrome (HPS), also called hantavirus cardiopulmonary syndrome (HCPS), is a severe respiratory disease caused by hantaviruses. The main features of illness are microvascular leakage and acute respiratory distress syndrome. Symptoms occur anywhere from 1 to 8 weeks after exposure to the virus and come in three distinct phases.
This outbreak was determined to be caused by a hantavirus, now named Sin Nombre virus, and represented the first confirmed instance of hantaviruses in the Americas as well as the discovery of a new type of disease caused by hantaviruses. The new disease was named "hantavirus pulmonary syndrome (HPS)".
The Hantavirus Study Group found eighteen people who had either serologic or PCR evidence of infection, most of them young adults. Physical examination of these people showed fever, rapid and shallow breathing , an abnormally fast heart rate (tachycardia), and low blood pressure (hypotension). Severe pulmonary edema was near-ubiquitous.
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.
Hantaan virus (HTNV) is the main cause of hemorrhagic fever with renal syndrome (HFRS) in East Asia. Hantaan virus is transmitted by the striped field mouse (Apodemus agrarius) In its natural reservoir, HTNV causes a persistent, asymptomatic infection and is spread through excretions, fighting, and grooming.
In rodents, hantavirus produces a chronic infection with no adverse sequelae. In humans, hantavirus produces two major clinical syndromes: hemorrhagic fever or pulmonary syndrome. European, Asian, and African rodent-borne hantaviruses cause hemorrhagic fever. The pulmonary syndrome is caused mainly by Sin Nombre virus and Andes virus in the ...
