Herpes simplex virus (HSV) can cause two types of herpes infections: HSV-1 and HSV-2. The main difference between the two is their usual site of infection.

HSV-1 commonly causes oral herpes, characterized by cold sores around the mouth. However, it can also infect the genital area through oral-genital contact.

On the other hand, HSV-2 typically leads to genital herpes when transmitted sexually but can occasionally affect the mouth as well.

Both viruses are contagious and lifelong once contracted, with periodic flare-ups that may vary in frequency and severity for each individual.
If you have any concerns about your health or potential exposure to either form of herpes virus - particularly if experiencing symptoms or seeking further information—please consult a healthcare professional for guidance specific to your situation.
