How is Herpes simplex I passed on?

Herpes simplex I is very contagious and is transmitted through the direct contact between the contagious area and broken skin via salvia.

If you or your partner has herpes I in the form of sores or cuts around the mouth, genitals or anus, there is an increased risk of passing it onto your partner through oral sex. This is because the herpes I virus travels in salvia and can infect your partners through breakages in your skin.

What are the complications of Herpes simplex I

Herpes usually does not lead to complications. Although, outbreaks are common and can be painful, they are more-so in individuals with a weak immune system. It can also infect the eyes, which left untreated can lead to loss of vision. Herpes simplex I can cause a higher risk of miscarriage, as well as premature labour. It is also possible for herpes I to be passed onto a baby during delivery. Herpes simplex I in babies can be very serious.

What is the difference between Herpes simplex I and Herpes simplex II?

Herpes Type I usually causes small, painful blisters on the lips, mouth, gums or skin around the mouth, commonly known as cold sores. Herpes simplex II causes painful blisters on the genitals and surrounding areas. Although both highly contagious, type I and II are different strains of the virus within the same family.
