It is estimated to affect at least 1 in 500,000 individuals per year, [1] and some studies suggest an incidence rate of 5.9 cases per 100,000 live births. [2] About 90% of cases of herpes encephalitis are caused by herpes simplex virus-1 (HSV-1), the same virus that causes cold sores.

Equine multinodular pulmonary fibrosis is a chronic lung disease of horses. There is evidence that the disease is caused by infection with a gammaherpesvirus , equine herpesvirus 5 . The disease affects usually adult horses reducing the ability to exercise as a result of the formation of nodular lesions in the lungs.
Clinical signs include cute small lesions, no bigger than 2 mm in diameter around the vulva in mares, and on the sheath in stallions. The small bumps blister and then rupture, leaving raw, ulcerated, painful sores.
