One of the most common lip lesions pediatricians and pedodontists may encounter is recurrent herpes labialis. Herpes Virus Type 1 is from the herpes virus family. Contact with infectious secretions of the mucosa of the mouth, skin, and eyes can lead to primary infection. Primary HSV-1 infections are subclinical and generally occur in children, teenagers, and young adults. Reactivation of the virus can cause an asymptomatic release of the virus into saliva and oral secretions, which is itself an important risk factor for the transmission of the disease. Herpetic whitlow, recurrent herpes labialis, and herpes keratitis are usually caused by reactivation of this virus. Recurrent herpes labialis infection is a potential professional risk for oral health care workers. The purpose of this letter was to inform health professionals about the clinical symptoms, complications, and treatment of the herpes virus.
