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 ...
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.
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 ...
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 Andes virus, a hantavirus found in South America, has even been found to spread through person-to-person transmission, raising concern about hantavirus evolution in the U.S. A hantavirus infection does not always mean HPS will arise, but the majority of hantaviruses in North, Central, and South America cause HPS.

Transmission to humans occurs mainly through the inhalation of aerosols that contain mouse salivas, urine, or feces. [5] [6] Transmission can also occur through consumption of contaminated food, bites, and scratches. [4] Human-to-human transmission of Andes virus was first claimed to be a part of a 1996 outbreak in southern Argentina.
There is currently a hantavirus vaccine that protects humans against hantavirus infections. The first vaccine was developed in 1990, and was initially used to fight the Hantaan River virus, which causes one of the most severe forms of Hantavirus Hemorrhagic fever with renal syndrome (HFRS). [ 12 ]
However, these places don't just include human beings but also other creatures and critters that were impacted by the historic storms. Hurricanes have a long history of impacting animals.
