Hantaviridae is a family of viruses in the order Bunyavirales . [1] It is named for the Hantan River area in South Korea where an early outbreak of one of its species was observed.

What Are Symptoms of Hantavirus? Since HPS affects a small population, the “incubation” period is unknown. In most recorded cases, symptoms develop 1 to 8 weeks after exposure. Early symptoms, such as fever, dry cough, body aches, headaches, diarrhea and abdominal pain, are similar to many other viral illnesses. This may prevent an HPS diagnosis before the illness progresses. If the initial symptoms are not connected to hantavirus exposure and are left untreated, late symptoms will onset rapidly. These symptoms include cough and shortness of breath, which are the result of leaky blood vessels and lead to collection of fluid in the lungs, bleeding and failure of the heart to pump. The combination of these changes can lead to shock, failure of several organs and even death. With this in mind, key symptoms and signs to watch for (with a history of rodent exposure) include: Fever greater than 101◦F, chills, body aches, headaches Nausea and vomiting and abdominal pain A dry coug...
The Hantaviruses are a group of rodent-borne viruses that cause illness in humans. The hantaviruses found in Europe and Asia cause a form of kidney disease called hemorrhagic fever with renal syndrome (HFRS). The hantaviruses in the Americas attack the lungs, causing hantavirus pulmonary syndrome (HPS). HPS was only identified as a disease occurring in the US in the 1990s. Key Facts: HPS is rare. According to the Centers for Disease Control and Prevention (CDC), 728 cases of the illness were identified in the United States between 1993 and 2017. Cases of HPS have been identified in 34 states, with 96% identified in states west of the Mississippi River. The hantavirus that is the predominant cause of HPS in the US is called the Sin Nombre virus. The deer mouse is the primary carrier of the virus, with other carriers including the white-tailed mouse, cotton rat and rice rat. The house mouse and Norway rat most frequently encountered in urban communities are not carriers. Sym...
