Cold sores, also known as fever blisters, are a common viral infection primarily caused by the herpes simplex virus type 1 (HSV-1). In some cases, herpes simplex virus type 2 (HSV-2)\u2014usually associated with genital herpes\u2014can also lead to cold sores, especially through oral-genital contact.<\/p>\n
What Causes Cold Sores?
\nCold sores are highly contagious and spread easily from person to person, most often through contact with infected saliva or skin. Common ways the virus is transmitted include:<\/p>\n
Direct contact: Kissing or sharing drinks, food, or utensils with an infected person.<\/p>\n
Indirect contact: Using items contaminated with the virus, like towels, lip balm, or cutlery.<\/p>\n
Self-infection (Autoinoculation): Touching a cold sore and then touching other parts of the body, such as the eyes or genitals, can spread the virus.<\/p>\n
Recognizing the Symptoms
\nCold sores tend to follow a series of stages:<\/p>\n
Tingling or itching: A burning or itching sensation is often the first sign, occurring 1\u20132 days before the sore appears.
\nFormation of blisters: Small, fluid-filled blisters develop, usually near the lips but sometimes on the nose or gums.
\nBlister rupture: The blisters break open, forming painful, red sores. This is the most contagious stage.
\nScabbing: The sores dry out and develop a crust, which eventually falls off during healing.<\/p>\n","protected":false},"excerpt":{"rendered":"
