About STD Risk Calculator
How should this app be used?
This app should only be used as a tool for understanding that sexual activity carries risk for infection. There are many complex factors that an app such as this cannot account for so and so one must always practice safer sex (i.e. use condoms). The only way to guarantee that you will not get a sexually transmitted infection (STI) is to abstain from sexual activity completely.
What is the different between single encounter risk mode and lifestyle risk mode?
Single encounter risk mode tells you about two things: (1) risk factors associated with your sexual partner and (2) the risk associated with your specific sexual behaviours. This mode can be used to analyze a specifical sexual encounter.
The lifestyle risk mode assesses your general risk for sexually transmitted infections (STDs) as a result of your lifestyle by using screening questions about behavioral and demographical factors.
Does this cover all infections?
No. There are a number of sexually transmitted infections (STIs) that are not covered by STD risk calculator. These include but are not limited to: scabies, lymphogranuloma venereum (LGV), public lice (i.e. crabs), trichomoniasis, yeast infections, shigella, hepatitis viruses, molluscum contagiosum and others.
STD Risk Calculator covers chlamydia, gonorrhea, syphilis, HPV, genital herpes, HIV and pregnancy.
Please explain STD vs STI.
This app is called STD Risk Calculator because the term STD is most often used in common language. However, there is a technical difference between STDs and STIs. A sexually transmitted infection (STI) refers to an infection that you can acquire as a result of sexual activity. A sexually transmitted disease (STD) is a disease that occurs as a result of an STI. Not all STIs will lead to STDs.

Risk Analysis
Unprotected anal sex is an extremely high risk activity for contracting HIV
The risk of contracting HIV from receiving anal sex is likely increased if your partner ejaculates in your anus
Condoms are highly effective at preventing HIV transmission as a result of vaginal or anal sex
Your sexual partner is a sex worker and therefore more likely to have HIV
Your sexual partner uses injection drugs and is therefore more likely to have HIV
Your sexual partner is a male who has sex with men and is therefore much more likely to have HIV than the general population
It is possible to contract HIV from giving unprotected oral sex to a male although this mode of transmission is relatively uncommon
It is possible to contract HIV from giving unprotected oral sex to a male especially if your partner ejaculates in your mouth although this mode of transmission is relatively uncommon
Because you are infected with Genital Herpes, you can contract HIV more easily from vaginal or anal sex
Often people who have only recently become infected with HIV are not aware they are infected although they are still able to pass on the virus by sexual contact

Pregnancy
Your behavior is
{{getPregnancyRiskTag()}}
Risk Behaviors
Receptive vaginal sex (no condom)
Insertive vaginal sex (no condom)
Partner ejaculated in your vagina
Risk Analysis
Having your partner ejaculate inside your vagina is a very high risk activity for pregnancy unless you are on birth control
Receptive vaginal sex without a condom is a high risk activity for pregnancy unless you are on birth control
Receptive vaginal sex with a condom is a lower risk activity for pregnancy but still carries a substantial possibility of pregnancy unless you are on birth control
Emergency contraception can prevent pregnancy from occurring if taken within 48-72 hours after having sex (even if your partner ejaculated inside your vagina)
Oral contraceptives or other forms of birth control are highly effective against pregnancy but only if taken as directed by your doctor

Recommendation
