What does a herpes rash look like and how is it diagnosed?

A herpes rash is caused by the herpes simplex virus (HSV-1 or HSV-2) and typically presents as painful blisters on the skin or mucous membranes. In this episode, we explain symptoms, transmission, and how herpes is assessed in Europe.

In this episode, we cover:

• What herpes simplex virus (HSV) is

• Differences between HSV-1 and HSV-2

• Early symptoms: tingling, burning, itching before rash appears

• Typical appearance: small fluid-filled blisters that ulcerate

• Common locations: lips (oral herpes) and genital area

• How herpes is transmitted (skin-to-skin contact)

• When antiviral treatment (aciclovir, valaciclovir) may be prescribed

• Recurrent outbreaks and triggers

• Red flag symptoms: severe pain, eye involvement, fever

Doctors assess lesion appearance, timing of symptoms, sexual history (if relevant), immune status, and recurrence pattern before recommending testing or treatment. Swab PCR testing may confirm diagnosis. Severe symptoms, widespread rash, or suspected eye involvement require urgent in-person evaluation.

This episode reflects how viral skin infections are reviewed within structured medical assessment in European telemedicine at Mobi Doctor.
