Some conditions may also cause you to have blood or protein in your urine. If you have a urinary problem, see your healthcare provider. Urinalysis and other urine tests can help to diagnose the problem. Treatment depends on the cause.
Cold sores are usually caused by the herpes simplex virus (HSV) type 1, which is transmitted by such forms of contact as kissing an infected person or sharing eating utensils, towels, or razors. Genital herpes is usually caused by herpes simplex virus type 2.
The medical name for the specific virus that causes cold sores is herpes simplex. There are two types of herpes simplex infection: herpes simplex virus one (called HSV-1 for short) and herpes simplex virus two (called HSV-2 for short).
