Summary
Ms. Heart received a 7-day course of doxycycline and abstained from sex for the full week. Anonymous contact tracing found that Ms. Hearts’ casual partner was also positive for chlamydia despite him showing no symptoms. The partner also had several other recent sexual contacts which were all successfully tracked and treated - good thing sexual health clinics work better than the government’s track and trace covid app.
Ms. Heart tested negative for blood-borne viruses and is now happy to continue using condoms as well as her COCP thanks to further counseling on the risks of STIs.
The absence of abdominal pain, cervical excitation, and systemic symptoms is important here as it helps distinguish between pelvic inflammatory disease and simple lower vaginal infection.
