In benign infections found in some wild and captive African elephants, these viruses can affect either the skin or the pulmonary system.[6] In the former case, it produces small pinkish nodules on the head and trunk in juveniles, which appear for a few weeks and then regress, suggesting an intermittently reactivated localized infection that mostly remains dormant.[2] In the second case, it has been found in small white pulmonary nodules on necropsy of many asymptomatic adults. These are both characteristic of EEHV2, EEHV3 and EEHV6.[2]
