There are a further five or six species/types and varieties of elephant gammaherpesvirus (EGHVs) found in eye and genital secretions of many healthy Asian and African zoo elephants - e.g. EGHV1, EGHV2, EGHV3A, EGHV3B, EGHV4 and EGHV5 (also called Elephantid herpesviruses EIHV3, EIHV4, EIHV5, EIHV6, ElHV9 and ElHV10 - which are gamma herpesviruses. But these are neither closely related to the EEHVs, nor the known cause of any disease symptoms.[3][15]
