Cold sores are also called fever blisters or oral herpes. They appear around the lips after being exposed to a virus, the herpes simplex virus 1 (HSV-1). There are several stages of development: from an itchy and red bump to a blister with a crust on the ulcer.

Most cold sores disappear after 10 days, but once you had the virus, it does not go away. It stays dormant in your body until something triggers it again. Cold sores are very contagious and also very common. In this post, you’ll learn about the causes of cold sores and how to treat them naturally.

What is herpes?

Herpes is characterized by HSV1 and HSV2 commonly termed as (Herpes simplex virus 1 & 2). Herpes is a viral skin infection but it is classified on the basis of the site of infection. These types include Oral, Genital, cerebral, meningitis, neonatal or simply Herpes.

ORAL HERPES

Fever blister or cold sores is the most common name for this type of herpes. Small blisters are developed around the face or mouth. These blisters around lips are strongly indicative of oral herpes.

GENITAL HERPES

It is simply referred as herpes. The main affected area of herpes is genital area. Painful blisters can develop here because of this herpes.

OTHER FORMS OF HERPES

The other types of herpes are mainly known by the name of encephalitis, herpes Whitlow, Neonatal Herpes and Bell’s palsy. These are very rare types of infections but if they are then they are very virulent in nature.

What could be the causes of cold sores?

Herpes transmits through direct contact. 

Herpes is very infectious and once it enters the body it remains there. It stays in the nervous system though may be dormant. But chances are high that it might relapse.

The strain of herpes simplex virus usually responsible for cold sores is known as herpes simplex virus type 1 (HSV-1). In rare cases, cold sores can also be caused by the herpes simplex virus type 2 (HSV-2). This can be the result of having oral sex with someone who has genital herpes.

Cold sores can be triggered by cold weather, stress, wind, sun, food allergies (especially nuts), or menstruation. Low thyroid function could have a link as well.

The incubation period for Herpes is between 2 to 20 days. In this time the Herpes develop from scabs to blisters and then later disappears. In acute cases the infection can spread to eye.

There is no evident cure for Herpes, though after being resident in the body the virus becomes asymptomatic.
