Although infection with Hendra virus is rare, the case fatality is high: 4/7 (57%).
To date no human-to-human outbreak has been documented.
High biosafety level viruses. Please, contact us via info@virusbankplatform.be to inform about toolbox access.
Genetically similar and low pathogenic Cedar virus currently used as a surrogate for the highly pathogenic Henipa viruses.
