Q

Counsel the patient on their chlamydia diagnosis

A
  1. Transmission, treatment, possible complications, measures to reduce risk of further STIs
  2. Refer to resources E.g. BASHH
  3. Advise to inform the current partner to also be treated for chlamydia - ‘partner pack’
  4. Sexual intercourse (including oral sex) should be avoided until the partner has completed treatment (or waited 7 days after treatment with azithromycin)
  5. If they are unwilling to comply, then use condoms
  6. All sexual contacts in the last 60 days should be tested
  7. We will give you antibiotics, you need to take them 3x a day for a week

There is a chance that it could heal by itself without treatment
However, there is also a chance that it goes on to cause very serious complications
(Female)
Infection of the pelvis → tubal infertility, ectopic pregnancy, chronic pelvic pain
Issues with pregnancy in the future → pre-term delivery risk
(male)
Infection of the tubes in the scrotum
Bowel issues
Arthritis secondary to infection
