Viral shedding is a real phenomenon in herpes where the virus can be present on the skin's surface even without visible symptoms. It can still be contagious during these times, so it's important to understand that transmission risk exists beyond outbreaks. Your doctors are right about waiting for at least a week after an outbreak before engaging in sexual activity to reduce this risk, but caution and preventive measures should always be taken as there is still some potential for viral shedding between outbreaks. If you have further concerns or questions regarding your specific situation, it would be best to consult with your healthcare provider for personalized advice and guidance tailored to your needs.
