Traditionally, HSV 1 (Herpes Simplex Virus Type 1) is commonly known as oral herpes while HSV 2 (Herpes Simplex Virus Type 2) causes genital herpes. However, due to changing sexual practices this is no longer true.
You can still get HSV 2 in the mouth via oral sex and similarly, you can get HSV 1 in the genitalia through oral sex.
Both HSV 1 and HSV 2 causes painful blisters and ulcers. Usually, there are more than 1 blister or ulcers. In some people, the symptoms can be very mild and they may not think they have been infected with herpes as they may have mistaken it for pimples, or the blisters or ulcers last for a just few days before disappearing.
However, that does not mean that the virus is no longer present.
Similar to the chickenpox virus, it can hide in your body for a period of time with no symptoms and can cause flare ups later on when your immune system is low. Rapid testing is therefore paramount for prompt treatment, should it be necessary.
