The time for symptoms after infection is related to the specific type of disease and needs to be analyzed specifically. 1. Infection with gonococcus: the incubation period of gonorrhea is usually short, and it is possible to have symptoms in 3-5 days. 2. Infection with syphilis: the incubation period is usually 2-4 weeks before it causes painless, hardened ulcers, i.e. the symptoms of a stage 1 chancre. 3. Condyloma acuminatum: it usually takes about 3 months for warts to develop in the external genital organs. 4. AIDS: It takes 2-6 weeks for most patients to develop symptoms similar to an upper respiratory tract infection, such as generalized body aches and pains and fever. 5. Genital herpes: the incubation period is generally 2-14 days, so patients infected with genital herpes virus, it will take 2-14 days before clinical symptoms appear. When the above symptoms appear, or when you suspect that you are suffering from STDs, you should go to the hospital in a timely manner and take active treatment, so as to avoid delaying the condition.
