First things first: What exactly is a cold sore? “Cold sores are small oral ulcers that are caused by the herpes simplex virus,” says Shilpi Agarwal, a board-certified family medicine and integrative and holistic medicine physician in Washington, D.C. The virus is mainly transmitted by close contact with skin or saliva, she says.
“The HSV-1 strain and HSV-2 are extremely similar. Originally it was differentiated because HSV-1 infects the mucous membranes near the mouth, lips, nose, and face and HSV 2 near the genitalia,” says Agarwal. “However, we have now been seeing that this is not always the case — sometimes HSV-1 is isolated in the genitalia.
The herpes virus lies dormant in the body and becomes activated by triggers such as stress, sun exposure, and physical trauma to the area. Also, shedding can happen even when symptoms aren’t present, so the potential is always there for the virus to be passed to a partner.
But spreading of the virus is less likely if there’s no outbreak. “Even after fully healed, you are still at risk of spreading HSV-1 since the virus remains dormant in the nerve roots and may be shed without any symptoms,” says Batra. However, the risk is much lower when no outbreaks are present, she adds.
