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.
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.
Unusual rains followed by drought led to a surge in the deer mouse population, which transmits hantavirus through excretions that humans can inhale, resulting in the often fatal hantavirus pulmonary syndrome (HPS). ENSO-driven rainfall increases food sources for rodents, indirectly raising the risk of human exposure to hantavirus. [8]
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) .
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 ...
The source of HPS was confirmed when the hantavirus associated with HPS was isolated from a deer mouse in the home of someone confirmed to have HPS. [4] Following virus isolation and PCR conducted on both the lung material from the mice and Vero E6 cell cultures were obtained, and the PCR sequences were found to be identical, confirming the ...
Editor’s note: As COVID-19 continues to spread worldwide, scientists are analyzing new ways to track it. One promising approach is training dogs to detect people who are infected by smelling ...
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.
