HSV stands for Herpes Simplex Virus, which is the virus that causes herpes infections. There are two main types - HSV-1 typically causes oral herpes (cold sores), while HSV-2 usually causes genital herpes. You're correct that HSV is commonly associated with herpes. As an STD assistant, I can provide factual information about herpes and other STDs, but for any personal medical concerns, it's best to consult a healthcare professional.
