Methods include barrier methods, contraceptive pill and intrauterine devices. Only the barrier method can prevent STIs Sex Protection: Safe sex is having sexual contact while protecting yourself and your sexual partner against sexually transmissible infections (STIs) and unplanned pregnancy. Vaginal swab: First-line investigation for suspicion of STI. You can perform high vaginal swab, low vaginal swab or swab from the cervix itself. Nucleic acid amplification test: Nucleic acid amplification is a valuable molecular tool not only in basic research but also in application oriented fields, such as clinical medicine development, infectious diseases diagnosis, gene cloning and industrial quality control. Polymerase chain reaction (PCR) was the first nucleic acid amplification method developed and until now has been the method of choice. PCR: Polymerase chain reaction (PCR) was the first nucleic acid amplification method developed. Pap smear: Quick and simple test used to check for changes to the cells of the cervix that may lead to cervical cancer. |
Introduction Sexually transmitted infections (STI) are a significant public health worldwide. STI can result in chronic disease, pregnancy complications, infertility, and even death. Globally, congenital syphilis is still a leading cause of stillbirth and neonatal death. Antibiotic-resistant Neisseria gonorrhoeae continues to be a significant public health concern. Chlamydia trachomatis infection is the most frequently reported sexually transmitted infectious disease in the United States and continues to be an important risk factor for pelvic inflammatory disease (PID), ectopic pregnancies, urethritis, cervicitis, chronic pelvic pain, and infertility. Treatment of STDs should also include treatment of patients' partners. Overall, patients, especially the younger population, should be screened regularly and counselled to ensure early diagnosis and treatment. Contraception does not prevent STI, protection such as condoms do.
