HIV risk in the previous 3 months and the future 3 months

The clinician should prescribe PrEP if the patient describes a history of any of the following
HIV acquisition risks in the previous 3 months and if the patient foresees that
there are likely to be similar acquisition risks in the next 3 months:

• At least one episode of condomless anal or vaginal intercourse (insertive or receptive) with a
  regular HIV-positive partner who is either not on treatment, or who is on treatment but has a
  detectable HIV viral load
• At least one episode of receptive anal or vaginal condomless intercourse with any casual
  HIV-positive partner or a man who has sex with men of unknown status
• Episodes of planned condomless insertive or receptive vaginal sex in an effort to conceive with
  an HIV-positive partner, regardless of the HIV-positive partner’s viral load

HIV risk in the future 3 months

The clinician should prescribe PrEP if the patient foresees that they will have HIV acquisition
risk in the upcoming 3 months, despite not having had HIV acquisition risk in the
previous 3 months:

• Future episodes of planned condomless insertive or receptive vaginal sex in an effort to
  conceive with an HIV-positive partner, regardless of the HIV-positive partner’s viral load
• When a person plans to travel to countries with high HIV prevalence during which time they
  anticipate having condomless sex with casual partners who are HIV positive or of unknown HIV
  serostatus
• When a person plans to return home to an overseas country which has a high HIV prevalence during
  which time they anticipate that they will be having condomless sex with casual partners
• When a person reports that they have recently left a monogamous relationship and will be having
  condomless sex with a casual HIV-positive partner, or a male or female partner of unknown HIV
  serostatus from a country with high HIV prevalence, or a male partner who is thought to have sex
  with men
• When a person presents with concerns of deteriorating mental health and a history of having had
  increased their HIV acquisition risk behaviour in this setting
• When a person presents with a history of intermittent binge drinking of alcohol or recreational
  drug use and a history of having had increased their HIV acquisition risk behaviour in this
  setting.

• When an HIV serodiscordant couple experience undue suffering and anxiety about inter-couple HIV
  transmission despite the positive partner being virologically suppressed on treatment.
