When you have herpes simplex, it is recommended that you do not have children for the time being during an outbreak and wait for it to heal before getting pregnant. Pregnant women who have herpes simplex virus infection, whether it is a first outbreak or a recurrence, may have more serious consequences. It can lead to abnormal development of the child in the womb, death, miscarriage, premature labor and severe infections after birth. Therefore, it is advisable not to have children during an outbreak, and to wait until it is cured before getting pregnant. Also, since the herpes virus can be transmitted sexually, men with the disease also need to be treated first, otherwise it can be passed on to women.
