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.

STD Risk Calculator

STD Risk Calculator lets you determine the risk of STDs based on a single sexual encounter or based on your lifestyle risk factors

By using this app you agree to our Terms and Conditions

It can happen to anyone. If you’re sexually active, it’s important that you know the real state of your health. Some activities may put you at higher risk of getting HIV or another STD, including:

  • Having multiple sexual partners
  • Using condoms incorrectly
  • Not using condoms at all
  • Abusing alcohol or drugs

Activities that may lower your risk of contracting an STD include:

  • Correct use of a condom
  • Being in a monogamous relationship with an STD-free partner

Left untreated, STDs can lead to serious long-term health complications, including infertility and pelvic inflammatory disease (PID). Many people with STDs will show little or no symptoms, so guessing your STD status by how you feel is not an accurate indicator of your true sexual health. The best way to know whether you have HIV or another STD is to get tested. If you’re sexually active, it’s best to take an STD, or STI, test regularly. This way, you can help keep yourself and any partners safe and informed.

What Is STD Risk Calculator?

STD Risk Calculator lets you determine the risk of STDs based on a single sexual encounter or based on your lifestyle risk factors.

In other words, STD Risk Calculator can help you better understand your risk of developing common STDs like gonorrhea, chlamydia, syphilis, human papillomavirus (HPV), genital herpes, hepatitis B, and human immunodeficiency virus (HIV).

STD testing doesn’t have to be scary!

Discreet, same-day STD testing is available. Since having HIV or another STD puts you at greater risk of developing another infection, an STD panel can help you get a more comprehensive picture of your health.

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
