hello, i can understand your concern. Glandular fever(Epstein Bar virus) and Herpes simplex are two entirely different diseases caused by different viruses. Even though they belong to herpes family, they are different Glandular fever is common in teenagers and spreads by kissing, coughing. This is self limiting and reduces by rest and supportive care. On the other hand, herpes simplex is a sexually transmitted infection and can spread from one person to another only through sexual contact(vaginal and oral sex can spread) If you had oral lesions and that point of time there is a chance of the virus spreading to genitals. If you still have lesions oral or genital kindly consult a doctor for a course of antiviral medication acyclovir. Herpes cannot be cured, hence you may have occasional out breaks where you need to take course of the medication again. Always use a condom to prevent spreading the virus to your partner. Hope i have answered our query. Thanks for choosing HCM
