Characterizing the Exposure Event
Placeholder: classify contact type and partner status first.
- Sexual: Contact type (placeholder category)
- Unknown/+: Partner status (placeholder factor)
- None/broke: Condom use (placeholder factor)
- Mucosal: Fluid exposure (placeholder factor)
Why exposure type matters
Placeholder: exposure type sets the baseline risk tier.
Hours-Since-Exposure Countdown
Placeholder: the PEP window closes hard at 72 hours.
- 72h: Window length (placeholder threshold)
- <2h: Ideal start (placeholder guidance)
- Time-dependent: Efficacy decay (placeholder note)
- PEP closed: Past 72h (placeholder outcome)
Why the clock matters
Placeholder: earlier PEP start improves protective effect.
PEP Pathway Routing
Placeholder: acute exposures within window route to PEP.
- Same day: Regimen start (placeholder timing)
- 28 days: Course length (placeholder duration)
- 6-12 wks: Follow-up test (placeholder schedule)
- Regimen sim: See also (placeholder cross-link)
What happens after routing
Placeholder: routed cases proceed to regimen selection tool.
Ongoing Risk Profile Assessment
Placeholder: score recurring behavioral and partner risk factors.
- 0-10: Risk score range (placeholder scale)
- 0-3: Low tier (placeholder cutoff)
- 4-6: Moderate tier (placeholder cutoff)
- 7-10: High tier (placeholder cutoff)
Why ongoing profile matters
Placeholder: repeated risk favors prevention, not one-off PEP.
PrEP Pathway Routing
Placeholder: sustained risk routes toward daily or on-demand PrEP.
- Risk ≥4: Eligibility signal (placeholder threshold)
- Risk ≥7: Strong signal (placeholder threshold)
- Labs + counsel: Start visit (placeholder step)
- Eligibility sim: See also (placeholder cross-link)
What happens after routing
Placeholder: routed cases proceed to eligibility screening tool.
Placeholder: this tool only triages — it does not prescribe regimens.
