The eastern deer mouse, the natural reservoir of Sin Nombre virus. Sin Nombre virus is carried chiefly by the Eastern deer mouse (Peromyscus maniculatus). Many other rodents, such as desert woodrats (Neotoma lepida), are considered to be dead-end hosts for SNV. The distribution of SNV closely matches that of its host's distribution.
In two cases in Pennsylvania, the patients were living in rural areas and had recent exposure to rodent excreta prior to the onset of symptoms. Both patients developed rapid onset of respiratory distress and pulmonary edema , believed to be the result of cytokine storm , and both expired within 5 days of onset of symptoms.
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.
Symptoms of hantavirus. Particles containing hantavirus get into the air when urine, saliva or poop from deer mice are stirred up, leading to hantavirus pulmonary syndrome (HPS).
The species of deer mouse that carries the Sin Nombre virus, in particular, is more likely to enter human dwellings than other deer mice species. [10] It is believed that other cases of hantavirus had been occurring regularly but which had simply been diagnosed as ARDS, which is often used as a way to classify unexplainable respiratory failure.
Between 1975 and 2023, cases of hantavirus pulmonary syndrome peaked throughout New Mexico in April, May, June and July. As hantavirus 'season' looms, state health officials urge residents to take ...
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.

Feb. 20—A San Juan County man was hospitalized with a case of hantavirus pulmonary syndrome — the first case of the respiratory disease reported this year, according to the state Department of ...
