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 ...
Differential diagnosis often requires detailed patient history, including recent exposure to rodent habitats, which the patient may not be aware of. Point-of-care and other quick molecular diagnostic tests for hantavirus are under development, which could improve rapid diagnosis in rural areas, typically where most hantavirus cases are found.
Pig-to-human transmission may also be possible, as one swine breeder was infected with hantavirus with no contact with rodents or mites. Hantaan virus and Puumala virus have been detected in cattle, deer, and rabbits, and antibodies to Seoul virus have been detected in cats and dogs, but the role of these hosts for hantaviruses is unknown.
