The duration of viremia patients with epidemic hemorrhagic fever. 1989

Z Q Yao, and W S Yang, and W B Zhang, and X F Bai

The duration of viremia in patients with epidemic hemorrhagic fever (EHF) was studied using immunofluorescence technique and cell culture assays. The duration of virus in plasma of EHF patients was about 1 week, which was concomitant with the febrile phase of the disease. Comparatively, the separation rate of viruses in peripheral blood mononuclear cells (PBMC) was greater (1.8 times) than in plasma, while the detected peak of EHF (in 4-7 days after onset of the disease) was found to be 2 or 3 days less than that of plasma, thus the detectable viremia was prolonged until the 8th to 11th day of the disease. High titre EHF antibody of IgG, TgM was unable to neutralize the virus in human blood. The results revealed that a blood-cell-associated prolonged viremia is one of the characteristics of EHF infection.

UI	MeSH Term	Description	Entries
D007963	Leukocytes, Mononuclear	Mature LYMPHOCYTES and MONOCYTES transported by the blood to the body's extravascular space. They are morphologically distinguishable from mature granulocytic leukocytes by their large, non-lobed nuclei and lack of coarse, heavily stained cytoplasmic granules.

D006476	Orthohantavirus	A genus of the family BUNYAVIRIDAE causing HANTAVIRUS INFECTIONS, first identified during the Korean war. Infection is found primarily in rodents and humans. Transmission does not appear to involve arthropods. HANTAAN VIRUS is the type species.

D006480	Hemorrhagic Fever with Renal Syndrome	An acute febrile disease occurring predominately in Asia. It is characterized by fever, prostration, vomiting, hemorrhagic phenonema, shock, and renal failure. It is caused by any one of several closely related species of the genus ORTHOHANTAVIRUS. The most severe form is caused by HANTAAN VIRUS whose natural host is the rodent Apodemus agrarius. Milder forms are caused by SEOUL VIRUS and transmitted by the rodents Rattus rattus and R. norvegicus, and the PUUMALA VIRUS with transmission by Clethrionomys galreolus.
