HSV-1 [Herpes Simplex Virus-1] is the primary cause of herpes labialis, also known as, cold sores or fever blisters. They are usually located on or around the lips. The infection is often obtained during childhood via non-sexual contact through sharing utensils, cups, and towels or receiving a kiss from a family member who has the virus. HSV-2 is a less common cause of fever blisters.

HSV-2 has been the most common cause of genital herpes, however, HSV-1 has become an equally common cause. Visually, there is no way to distinguish between HSV-1 and HSV-2. Outbreaks can cause painful blisters on the thighs, buttocks, and/or genitals.




Although there is no cure for herpes, you can receive treatment for your outbreaks.

You can be treated at the time of outbreak only or take daily medication to decrease the frequency of outbreaks.  Oral medications have been found to be more effective than topical medication. Using both topical and oral medication will not make the outbreak resolve faster. Some oral medications have a shorter treatment and do not need to be taken as often. You will be given the option to choose your treatment.

We do not diagnose herpes via our telemedicine service.
