A diagnosis of Herpes Simplex Virus (HSV) typically begins with a physical examination and a review of the patient's symptoms. A swab test from the affected area, such as a blister, can be used to confirm the presence of the virus. Blood tests may also detect antibodies to the virus, which can indicate a past or current infection. It's important to note that there is no herpes cure currently available, but antiviral medications can help manage symptoms and reduce the risk of outbreaks. Additionally, avoiding triggers, such as stress and sun exposure, can help prevent future outbreaks.
