# Understanding STD/STI Initials

I'd be happy to clarify! Here are common initials you might encounter:

**HSV-1 & HSV-2** = Herpes Simplex Virus types 1 and 2. Both can cause oral or genital herpes, though HSV-1 more commonly causes cold sores and HSV-2 more commonly causes genital herpes.

**STD** = Sexually Transmitted Disease (older term)

**STI** = Sexually Transmitted Infection (current preferred term—more accurate since infection doesn't always mean disease/symptoms)

**IgG & IgM** = Antibody types detected in blood tests. IgG suggests past or current infection; IgM suggests recent infection (though IgM results can be less reliable).

**PCR** = A sensitive test that detects viral DNA, often used during active outbreaks.

**Serology** = Blood test looking for antibodies to HSV.

If you're navigating herpes information or considering testing, that's completely understandable—many people have questions about what these terms mean. A healthcare provider can explain which tests might be relevant for your situation and what results actually indicate. Feel free to ask them to walk you through any results or terminology that feels unclear.
