What are the STIs with no visible signs?
It is possible to be infected with almost any STI and have no visible symptoms. Some STIs don’t show symptoms until serious, irreversible, permanent damage has already been done, and others have symptoms that are so mild that they are mistaken for other things (like a rash or bladder infection) or not noticed at all. If you are sexually active, you should not wait for symptoms to show before going to get tested.
