Sexually Transmitted Infection Question Day

Your STI questions answered this STIQ Day

Today (14 January) is Sexually Transmitted Infection Questions (STIQ) Day: a day designed to raise awareness about sexually transmitted infections (STIs), what they are, and how you can practise safe sex.

As a leading provider of sexually transmitted infection (STI) testing – also known as sexually transmitted disease (STD) testing – we know first-hand the importance of safe sex, and the health problems that can arise when an infection is left undiagnosed or untreated.

In this blog, we explain what STIs are, and answer some of the most common questions we are asked about STIs.

What are STIs?

STIs or STDs are infections that are passed on to other people during sexual activity.

Many STIs are spread via bodily fluids such as semen or vaginal fluids. However, they can also be passed on during skin-to-skin contact.

You can catch STIs from vaginal, anal and oral sex, sexual touching (e.g. touching genitals), and by sharing sex toys.

Some STIs, such as HIV, syphilis, and hepatitis, can also be spread via blood.

What is the difference between an STI and an STD?

STI (Sexually Transmitted Infection) and STD (Sexually Transmitted Disease) are umbrella terms that are used to refer to infections that are commonly spread via sexual activity.

These terms can be (and often are) used interchangeably to describe infections caused by bacteria, viruses or parasites that are spread via bodily fluids (e.g. semen, vaginal fluids, blood) or during skin-to-skin contact with an infected person.

The term ‘STD’, however, has become less popular over time, possibly due to the negative connotations that are sometimes associated with the word ‘disease’.

How often should I get tested for STIs/STDs?

If you are sexually active, taking an STI test is the most reliable way of making sure you’re staying safe, and reducing the risk of passing an STI onto someone else.

For people who are sexually activity, a comprehensive sexual health check is recommended once a year and should include a multi-panel test such as our 7-panel STI test, and at least one blood test such as our Herpes & Syphilis test, HIV test, HIV & Syphilis or Syphilis, Hepatitis C & HIV test.

If you are in a high-risk category and/or engage in frequent sexual activity with multiple partners, you may want to consider having a comprehensive sexual health check every 3-6 months.

What are some common STI symptoms?

Some of the most common symptoms that have been linked to several STIs/STDs include:

  • A burning sensation when urinating
  • Unusual and/or strong-smelling discharge from the penis or vagina
  • Burning and itching around the genitals
  • Pain during sex
  • Unusual bleeding from the vagina

I have no symptoms – could I still be infected?

Yes. In fact, when it comes to STIs, it’s very important to remember that you can still be infected even if you are not currently experiencing any symptoms. This is known as being asymptomatic.

When a person is asymptomatic, it greatly increases the risk of infections being passed on to other people during sexual activity, as they may not know they have an infection unless they take an STI test.

This makes regular STI testing extremely important, especially for people who are high risk or engage in frequent sexual activity with multiple partners.
