are herpes type 1 and 2 the same?

HSV-1 is mainly transmitted by oral-to-oral contact to cause oral herpes (which can include symptoms known as “cold sores”), but can also cause genital herpes. HSV-2 is a sexually transmitted infection that causes genital herpes. Both HSV-1 and HSV-2 infections are lifelong.

Herpes simplex virus (HSV) is a virus that usually causes skin infections. There are two types of HSV: HSV type 1 usually causes small blisters on the mouth, eye or lips (cold sores) and HSV type 2 usually affects the genital area. HSV infection in newborn babies can be very severe and can even cause death.

People who already have HSV-1 infection are not at risk of getting it again, but they are still at risk of acquiring herpes simplex virus type 2 (HSV-2) genital infection (see below).

Herpes simplex virus type 1 (HSV-1; human herpesvirus 1) and varicella-zoster virus (VZV; human herpesvirus 3) are human neurotropic alphaherpesviruses that cause lifelong infections in ganglia.

A positive test result for HSV-1 or HSV-2 indicates that you've contracted either virus at some point. The results also allow your doctor to differentiate between HSV-1 and HSV-2, which isn't always possible by visually examining the sores.

Most commonly, herpes type 1 causes sores around the mouth and lips (sometimes called fever blisters or cold sores). HSV-1 can cause genital herpes, but most cases of genital herpes are caused by herpes type 2. In HSV-2, the infected person may have sores around the genitals or rectum.

PCR finds the genetic material (DNA) of the HSV virus. This test can tell the difference between HSV-1 and HSV-2. Using the PCR test on skin sores isn't common. PCR is used mainly for testing spinal fluid in rare cases when herpes may have caused an infection in or around the brain. Antibody tests.

But sometimes it takes years for the first outbreak to happen. The first herpes outbreak lasts about 2 to 4 weeks. Even though the blisters go away, the virus stays in your body and can cause sores again.

No. Having cold sores now or as a child does not make you immune to genital herpes. Usually, cold sores on the mouth are caused by the HSV-1 virus and genital sores are caused by the HSV-2 virus. So someone who has HSV-1 can still get an infection with HSV-2.

What are HSV-1 and HSV-2? The herpes simplex virus (HSV) is a double-stranded DNA virus with an enveloped, icosahedral capsid. It is a common cause of infections of the skin and mucous membranes, manifesting itself as tiny, clear, fluid-filled blisters usually around the mouth or genitals.

HSV-1 is a subtype of the herpes virus that typically causes oral herpes. This is also known as cold sores. HSV-1 can also cause genital blisters that appear very similar to the genital blisters associated with HSV-2 virus.

No. Although cold sores and canker sores are often confused with each other, they are not the same. Cold sores, also called fever blisters or herpes simplex type 1, are groups of painful, fluid-filled blisters. Unlike canker sores, cold sores are caused by a virus and are extremely contagious.

Though similar in name, herpes zoster is not the same disease as herpes simplex (which is caused by the herpes simplex virus causing cold sores, fever blisters, or genital herpes).
438567
HSV1 and HSV2 are genetically similar, so the body of a person with the infection will produce antibodies to fight the virus and potentially reduce the risk of contracting the other form. Nonetheless, it is possible to have both types of HSV.
364865
HSV-1 is often called the cold sore virus and HSV-2 the genital herpes virus. However, either type can be in either location. You can have one type of herpes and still get the second type. For example, you can get HSV-1 on your mouth during childhood, and still get HSV-2 years later through sexual contact.
879261
Both HSV1 and HSV2 can occur in either the oral or genital regions, but having one form of the herpes simplex virus does not mean you will get the other.

Herpes outbreaks usually last for about one to two weeks, though the first outbreak after infection may last longer.
