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 ...
Orthohantavirus is a genus of viruses that includes all hantaviruses (family Hantaviridae) that cause disease in humans. Orthohantaviruses, hereafter referred to as hantaviruses, are naturally found primarily in rodents. In general, each hantavirus is carried by one rodent species and each rodent that carries a hantavirus carries one hantavirus ...
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 ...
While several species are responsible for Hantavirus hemorrhagic fever syndrome (HFS) and Hantavirus pulmonary syndrome (HPS), each species of hantavirus is unique to a single reservoir. This makes host evolution and geography important factors in understanding transmission and prevention of spread of disease to humans. [6]
“Weather can influence hantavirus occurrence in complicated ways — for example, heavy spring rains might increase food resources for deer mice resulting in an increase in the rodent population ...
Morgan said if a “hantavirus season” exists in New Mexico, it likely would be considered spring and summer — a time when the number of rodents increases and residents are more likely to find ...

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.
