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.
In addition to lung involvement, BAYV infection can affect the heart, kidneys, and liver, leading to complications such as acute kidney injury and systemic inflammatory response syndrome (SIRS). [11] This is due to the Hantavirus' ability to infect a range of endothelial cells.
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 ...
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.
Unlike a sudden cardiac event—say, a heart attack—valvular disease develops slowly, over five to 10 years. Many patients don’t experience symptoms until later in the course of disease, if at ...
Sin Nombre virus (SNV) is the most common cause of hantavirus pulmonary syndrome (HPS) in North America. Sin Nombre virus is transmitted mainly by the eastern deer mouse (Peromyscus maniculatus). In its natural reservoir, SNV causes an asymptomatic, persistent infection and is spread through excretions, fighting, and grooming. Humans can become ...
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.

Andes virus (ANDV) is the most common cause of hantavirus pulmonary syndrome (HPS) in South America. Andes virus is transmitted mainly by the long-tailed pygmy rice rat (Oligoryzomys longicaudatus). In its natural reservoir, ANDV causes an asymptomatic, persistent infection and is spread through excretions, fighting, and grooming. Humans can ...
