What causes Cold Sore on Tongue?

Cold sores on the tongue, also known as oral herpes or fever blisters, are primarily caused by herpes simplex virus type 1 (HSV-1). Here are the key factors involved in the development of cold sores:

1. Herpes simplex virus type 1 (HSV-1) infection: HSV-1 is a highly contagious virus that is usually spread by direct contact with an infected person. It can be spread through activities such as kissing, sharing utensils or drinks, or oral sex. Once the virus enters the body, it remains dormant in nerve cells near the base of the skull until it becomes active again, causing cold sore outbreaks.
2. Weakened immune system: A weakened immune system can increase the likelihood of a fever blister outbreak. Factors that can weaken the immune system include stress, fatigue, illness, certain medications or other underlying health conditions.
3. Triggers: Various triggers can stimulate the reactivation of the herpes simplex virus and lead to cold sore outbreaks. Common triggers include
4. Illness or fever: A weakened immune system during times of illness or fever can trigger a cold sore outbreak.
5. Emotional stress: Stressful events or emotional distress can activate the virus and lead to cold sores.
6. Sun exposure: Overexposure to sunlight, especially on the lips or face, can trigger a cold sore outbreak.
7. Hormonal changes: Hormonal changes, such as those that occur during menstruation, may be associated with cold sore outbreaks in some people.
