The duration of herpes outbreaks can vary. Typically, the first outbreak may last longer (2-4 weeks) compared to subsequent outbreaks which usually resolve within a week or so. Outbreaks are often triggered by factors like stress, illness, fatigue, or sun exposure. Proper treatment and management with antiviral medications prescribed by healthcare providers can help reduce the duration and severity of outbreaks. If you have concerns about your specific situation, it's best to consult a healthcare professional for personalized advice and care tailored to your needs.
