Treating your own infection solves half the problem. If a partner remains untreated, two things follow: they may develop complications, and you are likely to be reinfected.
The reinfection point is the one people underestimate. A cycle of treatment, reinfection and re-treatment is common, and it means repeated antibiotic exposure — which matters especially for gonorrhoea, where resistance is rising and ceftriaxone-resistant cases are being detected in England.
You Do Not Have to Do It Yourself
Sexual health services do partner notification routinely, and can contact partners without naming you. The message says that someone they have been in contact with has tested positive for a specific infection, and that they should get tested.
Options generally include:
- Provider referral — the clinic contacts partners, anonymously
- Patient referral — you tell them, with the clinic's support and often with a slip or code to take to a service
- Conditional referral — you agree to tell them within a set period, and the clinic does it if you have not
There is no obligation to have the conversation personally if you do not want to.
How Far Back to Go
This depends on the infection and how long it may have been present. Look-back periods differ — a recent gonorrhoea infection has a shorter window than syphilis, which can be carried without symptoms for a long time.
The clinic will advise on the appropriate period. Be honest with them about numbers and timing; they are not scoring you, they are scoping who needs a test.
If You Are the One Contacted
Get tested, and follow the advice about whether to be treated before results come back. For some infections, treatment of contacts is offered without waiting, because the risk is high enough and the cost of delay is a spreading infection.
Being contacted is not an accusation and does not tell you who or when. It tells you that a test is worth having.
The Awkward Conversation
If you do tell someone yourself, a few things help:
- Keep it factual: what the infection is, that it is treatable, and that they should get tested
- Do it in a way that lets them react privately — a message is entirely acceptable
- Point them at where to get tested
- Expect that it may be uncomfortable, and remember the alternative is worse for them
Abstain During Treatment
Follow the advice you are given about when it is safe to have sex again — commonly until treatment is complete and partners have been treated too. Resuming too early is one of the more common causes of the reinfection cycle.
Test of Cure
For some infections, notably gonorrhoea and mycoplasma genitalium, a follow-up test after treatment is standard. Attend it. Feeling better is not the same as being clear, and with resistant organisms circulating, that follow-up test is how a treatment failure gets caught before it spreads.
The Public Health Argument, Briefly
None of this is moralising. Partner notification is simply the most effective single intervention for interrupting transmission, and it is the reason sexual health services put resources into it. Doing it costs you a conversation, or not even that if the clinic does it for you.
