Primary infection is characterized by swelling of the conjunctiva and eyelids (Blepharoconjunctivitis) and small white itchy lesions on the corneal surface. The severity of the lesions varies, ranging from minor epithelial damage (superficial punctate keratitis) to more severe consequences such as the formation of dendritic ulcers. Humans are commonly infected with HSV. It is estimated that one-third of the world's population is infected regularly.
