A 25-year-old female presents with painful blisters around her mouth that appeared a few days ago. She also has a low-grade fever and malaise. What is the likely diagnosis, and how should it be managed?
This patient's symptoms suggest an outbreak of oral herpes, also known as herpes labialis or cold sores, typically caused by Herpes Simplex Virus type 1 (HSV-1). Management includes supportive care such as pain relief, as well as antiviral therapy with medications like acyclovir, which can shorten the duration of the outbreak if started early.
