HSV1 vs 2

HSV1 vs 2

What do you know about herpes infections? Is it all about having cold sores on the mouth? Or is it more than that? HSV1 and HSV2 are the two main types of the herpes simplex virus. These types may be closely related, but they still have significant differences, especially in the location of infection and severity of the condition.

Consider the essential details about HSV1 vs 2. Learn the most common distinctions of these infections. The information below explains the vital facts of each type, with preventive measures that you can follow.


What is the difference between HSV1 and HSV2

Understanding the standard terms used in herpes 1 vs herpes 2 will help you identify which of each type occurs when the virus enters your body. HSV1 is commonly called oral herpes, while HSV2 is genital herpes. These terms also explain and suffice the question: what is the difference between HSV1 and HSV2?


The most common difference between HSV1 and HSV2 is the form of transmission. HSV1 spreads via oral-to-oral contact with someone infected with herpes. The transmission rate is high if symptoms are present, such as cold sores or fever blisters on the mouth. However, you must also note that even asymptomatic individuals still spread the infection.


HSV1 usually develops on the lips, which can be annoying and itchy. Although not typical, HSV1 can also cause genital herpes. Such a case results from fellatio, also known as oral sex.


Meanwhile, HSV2 is a sexually transmitted infection. The disease spreads through sexual contact, especially in unprotected sexual intercourse. Its symptoms include the appearance of blisters on the genital area, pain and inflammation on the skin surrounding the genitals, and a tingling sensation in the affected area. Like HSV1, people with HSV2 can also be asymptomatic. It means that transmission is still possible regardless of the absence of symptoms.


Compared to HSV1, HSV2 is less common. Although the percentage of people having genital herpes is lower than oral herpes, it is still widespread. Like oral herpes, it is also a lifelong infection that has no known cure. Thankfully, antiviral drugs are available to treat these infections.


HSV 1 IgG type specific AB

The widely-used test form to diagnose oral herpes is HSV1 IgG type-specific for AB (antibody). IgG stands for Immunoglobulin G, also known as the Western Blot HSV-1 test. IgG is an antibody produced by the body as a defense mechanism when the herpes simplex virus infects a person.


Before this test, the healthcare professional will see if symptoms of herpes are visible. Since not all individuals show signs, this is where the HSV1 IgG test becomes essential. It is recommended to wait for 12-16 weeks after the initial exposure to the virus when deciding to take this test. That way, you will receive an accurate test result.


HSV 1 positive meaning

Below is the range of HSV1 test results:


  • Negative – 0.90 IV or less
  • Equivocal – 0.91 – 1.09 IV
  • Positive – 1.10 IV or more


What is an HSV1 positive meaning? An HSV1 test involves a number value that measures your status regarding herpes infection. If you get a 1.10 IV or more than that, you are positive. It means that the test has detected a significant level of IgG antibodies in your blood. That explains a current or previous HSV1 infection.

If you suspect being exposed to herpes, go to the nearest clinic or hub to get yourself tested. If you show symptoms, the diagnosis can be easy; however, participate in the HSV1 IgG test if you are asymptomatic.
