The herpes simplex disease is commonly associated with painful small rashes that itch and rupture clear fluid leaving a slow healing wound that finally ends with a black scar. Type-1 causes rashes and ulcers on the face, mouth and trunk. Type-2 causes skin rashes and ulcers over the genitals, thighs and buttocks and can be transmitted from mother to newborn. Type-1 can also cause damage to the tissues of the eyes. The mouth ulcers are what is sometimes called 'night fever' or 'cold sores'. Painful urination is also a common feature in the genital type. After the first infection the virus tends to inhabit the nerves and may appear inactive until the person's immune system is challenged by circumstances like pregnancy, poor nutrition, fever or menstrual cycle.
