Herpetic stomatitis is a viral infection affecting the mouth, which results in inflammation and formation of ulcers. These oral ulcers are different from canker sores in that they are caused by different viruses. Also, canker sores are not contagious, whereas herpetic stomatitis is.
Causes of Herpetic Stomatitis
Herpes simplex virus or HSV-1 is the cause behind herpetic stomatitis. This condition is commonly seen in young children and is usually the child's initial exposure to the herpes virus. Any break or injury in the skin allows this virus to enter the body. Skin or physical contact with an infected person transmits this infection. Any adult of the child's family could have a cold sore when the child develops herpetic stomatitis.

Investigations for Herpetic Stomatitis
- Examination of the mouth sores is usually sufficient for diagnosis.
- Further tests, such as a sample of the tissue and fluid from the ulcers, can be sent for testing and culture can be done to confirm the diagnosis.
- Tzanck smear is a staining test, which reveals the nonspecific changes in the cell nucleus occurring from HSV.
