The clinical courseamong these patients was similar to that described for patients with KoreanHemorrhagic Fever, Nephropathica Epidemica of Scandanavia and Hemor-rhagic Fever with Renal Syndrome of the U.S.S.R. The overall mortalitywas 11.2％. Sera obtaincd from some of these patients as well as frompatients admitted to the First Attached Hospital of Hubei Provincial Me-dical College were tested against an antigen associated with Korean He-morrhagic Fever and showed exceedingly high antibody titers. We concludethat EHF in Centfal China represents the same disease process as KoreanHemorrhagic Fever.展开更多

The incubation period usually lasts 5 to 7 d and approximately95% of the patients appear signs within 21 d after exposure. Typical features include fever,profound weakness, diarrhea, abdominal pain, cramping, nausea and vomiting for 3-5days and maybe persisting for up to a week. Laboratory complications including elevated aminotransferase levels, marked lymphocytopenia, and thrombocytopenia may have occurred.Hemorrhagic fever occurs in less than half of patients and it takes place most commonly in the gastrointestinal tract. The symptoms progress over the time and patients suffer from dehydration, stupor, confusion, hypotension, multi-organ failure, leading to fulminant shock and eventually death. The most general assays used for antibody detection are direct IgG and IgM ELISAs and IgM capture ELISA. An IgM or rising IgG titer(four-fold) contributes to strong presumptive diagnosis. Currently neither a licensed vaccine nor an approved treatment is available for human use. Passive transfer of serum collected from survivors of Junin virus or Lassa virus, equine IgG product from horses hypervaccinated with Ebola virus, a "cocktail"of humanized-mouse antibodies(ZMapp), recombinant inhibitor of factor VIIa/tissue factor,activated protein C, RNA-polymerase inhibitors and small interfering RNA nano particles are among the therapies in development. Preclinical evaluation is also underway for various vaccine candidates. One is a chimpanzee adenovirus vector vaccine; other vaccines involve replication-defective adenovirus serotype 5 and recombinant vesicular stomatitis virus.展开更多
