Oral herpes is also known commonly as cold sores and fever blisters but is different entity from oral canker sores although canker sores may sometimes be associated with HSV infection. Canker sores occur solely inside the mouth. Oral herpes occurs inside and around the mouth. Most of the time HSV-1 causes mouth symptoms and in a minority of cases it may also be responsible for genital symptoms. The opposite is true for HSV-2 – it causes genital symptoms in the majority of cases while only a few cases of HSV-2 infection will result in mouth symptoms. HSV-1 infection may be seen in all ages, including children, but when genital herpes is seen in children, sexual abuse needs to be a consideration.

Basically, even if a herpetic flare is untreated, the entire course of the flare from prodromal symptoms to complete resolution will take about ten days to three weeks. The body is capable of handling such an infection to minimise the effect of it as such.When we prescribe medications for a herpes flare, it’s usually antiviral tablets or creams. Sometimes a steroid course is necessary. These are all in the hopes of expediting the healing process, not as a cure for the virus. Like earlier mentioned, you can be symptom-free, but still, be having the virus in your body waiting for your antibodies to be distracted leaving it free to flare up again.

A doctor will base a presumptive diagnosis on information provided by the patient and on the physical examination. The characteristic appearance of the herpes sores leaves little doubt about the diagnosis, so the typical appearance of the sores is key to the diagnosis. This appearance helps distinguish oral herpes from oral thrush, shingles, gonorrhea, and syphilis. In addition, chapped or sunburned lips can resemble oral herpes, but the tissue stain (Tzanck smear, see below) shows no virus-induced cell changes. Further testing is usually not necessary but is sometimes done.
