STI Exposure Calculator

Mathematical Formula

2n – 1 = x

  • 2: Represents you (1) and your partner (+1 = 2)
  • n: Represents you and your current partner’s number of sexual partners (this is a compounding number – assuming that each person you have had sex with has had the exact same number of partners as you)
  • 1: Represents your current partner (this remains the same)
  • x: The number of people you have been exposed to

Here you can create the content that will be used within the module.

Example

  • Let’s say you have had 4 partners. Assuming your current partner has also had 4 partners, you would calculate 2 to the 4th power (2x2x2x2=16), and subtract 1. You have been exposed to 15 different people and any infection they may have had. This calculation is realistic, but not exact.
