HSV-1 and HSV-2 are both types of herpes viruses that can cause genital infections.

The main difference between HSV-1 (herpes simplex virus type 1) and HSV-2 (herpes simplex virus type 2) is their usual site of infection:

HSV-1 typically causes oral herpes, which includes cold sores around the mouth or on the face.
HSV-2 usually results in genital herpes, causing sores in the genital area.
However, it's important to note that either strain can infect orally or genitally through different modes of transmission.

It’s crucial to consult a healthcare professional for proper diagnosis and treatment if you suspect you have been exposed to either form of the virus. Feel free to reach out with any more questions!
