Gonorrhea is caused by Neisseria gonorrhoeae, a Gram-negative diplococcus bacterium that thrives in warm, moist mucosal areas of the human body. Transmission occurs primarily through unprotected vaginal, anal, or oral sexual contact with an infected partner. The bacteria target columnar and transitional epithelium, making the endocervix, urethra, rectum, and conjunctiva common entry points. In the Nigerian context, high prevalence rates among sexually active young adults necessitate routine screening during antenatal booking visits. Vertical transmission from an infected mother to her newborn during vaginal delivery is another critical route of infection, often leading to severe eye inflammation in the neonate.
Once the bacteria invade the mucosal tissue, they trigger a strong inflammatory response characterized by polymorphonuclear leukocyte infiltration and purulent exudate. Many women experience mild or non-specific symptoms, which contributes to delayed treatment and increased complication rates.
Accurate diagnosis relies on identifying the organism through laboratory testing. Endocervical swab microscopy using Gram staining provides a rapid initial assessment, readily revealing intracellular Gram-negative diplococci within neutrophils. However, culture on Thayer-Martin medium remains a gold standard, especially for testing antibiotic sensitivities. In many resource-constrained primary health clinics across Nigeria, syndromic management guidelines are used alongside rapid diagnostic tests when laboratory backup is limited. Antenatal screening protocols mandate offering STI testing at the first booking visit and repeating it in the third trimester for high-risk clients to prevent late-term ascending infections.
Pharmacological management requires dual therapy to cover potential coinfections like Chlamydia and to slow down antimicrobial resistance. Current World Health Organization and national treatment guidelines recommend a single intramuscular dose of ceftriaxone combined with oral azithromycin. Midwives must ensure that all drug allergies are checked before administration. Treating only the index patient is insufficient; concurrent treatment of sexual partners is mandatory to break the cycle of reinfection. Test-of-cure is typically reserved for pregnant women or cases where symptoms persist after the completion of treatment.
Untreated gonorrhea in pregnancy poses severe threats to both mother and baby. In the upper reproductive tract, the infection can cause Pelvic Inflammatory Disease (PID), chronic pelvic pain, and tubal factor infertility. Pregnant women face heightened risks of spontaneous abortion, preterm premature rupture of membranes (PPROM), chorioamnionitis, and postpartum endometritis.
For the newborn, exposure during birth commonly leads to ophthalmia neonatorum (neonatal conjunctivitis), a severe purulent eye infection that can cause corneal ulceration and permanent blindness if prophylaxis is neglected. Routine instillation of tetracycline eye ointment immediately after birth is a vital preventive safeguard.
Midwives occupy a frontline position in controlling the spread of sexually transmitted infections through health education and confidential counseling. Antenatal health talks must emphasize safe sexual practices, correct and consistent condom use, and the importance of early reporting of symptoms. Partner notification and contact tracing are sensitive yet essential responsibilities. Midwives should provide partner notification slips or invite partners directly to the clinic in a non-judgmental, confidential environment. Overcoming social stigma and fear of disclosure requires tact, empathy, and strict patient confidentiality.
