We often encounter such patients in the clinic. In fact, they cannot be called real patients, but they visit the clinic again and again after high-risk behaviors, suspecting whether they are infected with STDs and HIV, etc. What are the tests that need to be done after high-risk behavior? Within one week to two weeks after high risk, if there are symptoms such as redness, swelling, pain, pus flowing from the urethra/vaginal opening (female) in the genital area, it may be a bacterial infection, chlamydial infection or herpes virus infection, or it may be glansitis (male) or vulvovaginitis (female), if it is the former you need to do a bacterial, chlamydial, herpes virus test (possibly blood test); if it is the latter you need to check if There is a fungal infection that requires simple treatment just to get better. If you have symptoms such as ulcers, lumps, or red lesions on the hands and feet within two weeks to one month, you should suspect the possibility of syphilis, and you need a syphilis test; within one to three months, if you have symptoms, painless lesions, or if you have doubts in your mind, you are advised to go to the hospital regularly for syphilis, HIV, and genital herpes blood tests. From two weeks to ten months after high risk, HPV infected patients will develop proliferative lesions and warts on their genital area or body. Most patients will develop warts about three months after infection. The main reason for this is to check the pathogens of the affected area, and the main reason for the examination of warts is to check the local warts. To summarize, after high risk disease exclusion check time sequence: bacteria – Chlamydia trachomatis – herpes virus – syphilis C HIV virus – HPV infection – condyloma acuminata HIV infection and AIDS can be early detection, if the check HIV antibody positive will be transferred to Youan, Ditan Hospital for further confirmation and regular treatment.
