- Elephant Endotheliotropic Herpesvirus (EEHV) is a double-stranded DNA virus that is classified in the family Herpesviridae, subfamily Betaherpesvirinae, genus Proboscivirus, and species Elephantid betaherpesvirus.
EEHV causes acute, fatal haemorrhagic disease in wild and captive juvenile Asian and African elephants. If severe, EEHV can result in death within 24 hours of infection. Asian elephants are an endangered species, therefore EEHV poses a severe threat to conservation efforts. EEHV consists of eight genotypes that include EEHV1 through EEHV6, each varying in their lethality. EEHV strains exhibit some level of elephant species tropism:EEHV1, Asian species
EEHV1A, Asian species
EEHV1B, Asian species
EEHV2, African species
EEHV3, Asian and African species
EEHV4, Asian species
EEHV5, Asian species
EEHV6, African species
