• The EEHV viruses have co-evolved with elephants for millions of years. EEHV1, EEHV4, and EEHV5 are found in Asian elephants, and EEHV2, EEHV3, EEHV6 and EEHV7 are found in African elephants.
  • EEHV infection in elephants is a natural part of elephant biology, and most elephants carry EEHV without becoming ill. This is similar to how many herpesviruses behave in other species, including people.
