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.
Hantavirus hemorrhagic fever with renal syndrome (HFRS) is a hemorrhagic fever caused by hantaviruses. Symptoms occur usually occur 12–16 days after exposure to the virus and come in five distinct phases: febrile, hypotensive, low urine production (oliguric), high urine production (diuretic), and recovery.
For HPS, initial symptoms are flu-like, with fever, headache, and muscle pain, followed by sudden respiratory failure. HPS has a much higher case fatality rate than HFRS, at 30–60%. For both HFRS and HPS, illness is the result of increased vascular permeability, decreased platelet count, and overreaction of the immune system.
Sin Nombre virus infection usually causes hantavirus pulmonary syndrome (HPS), also called hantavirus cardiopulmonary syndrome (HCPS). Symptoms occur within 1–8 weeks after exposure to the virus and come in three phases: prodromal, cardiopulmonary, and recovery.
Andes virus infection usually causes hantavirus pulmonary syndrome (HPS), also called hantavirus cardiopulmonary syndrome (HCPS). Symptoms occur within 1–8 weeks after exposure to the virus and come in three phases: prodromal, cardiopulmonary, and recovery.
Hantaan virus was the first hantavirus to be discovered, and the group is named after the virus. The vast majority of HFRS cases occur in China, where Hantaan virus is responsible for up to 70% of cases. Cases of HFRS caused by Hantaan virus also occur in South Korea, Russia, and Vietnam.
Initial Symptoms (Prodromal Phase) BAYV and other hantavirus infections begin in the first few days and have general symptoms, including fever, fatigue, headache, chills, and dizziness. [6] Gastrointestinal symptoms, such as nausea, vomiting, diarrhea, and abdominal pain, are also seen during the initial stages. The non-specific symptoms make ...
The epidemiology of hantavirus correlates with the trends of the English sweating sickness. Hantavirus infections generally do not strike infants, children, or the elderly, and mostly affect middle-aged adults. In contrast to most epidemics of the medieval ages, the English sweating sickness also predominantly affected the middle-aged.
