Viral infections through sexual intercourse, most commonly genital herpes and condyloma acuminata, are diagnosed by combining the patient’s sexual history and clinical manifestations. If there is a blister-like new organism on the genitals or if there is exudation, blood tests should be taken in time to determine that it is genital herpes, which requires antiviral medication, oral ganciclovir tablets, local application of ganciclovir ointment and, if necessary, intravenous drip acyclovir injection powder for treatment. The main manifestation of the warts is the cauliflower-like growth on the external genitalia, which should be spotted with a laser, followed by antiviral and interferon treatment.
