Sexually Transmitted Infections

Talking about STIs and safe sex will provide you with the information you need to know to protect yourself and protect your partner

What is a Sexually Transmitted Infection?

An STI is an infection passed from person to person through intimate sexual contact - STIs are sometimes called Sexually Transmitted Diseases (STDs), however most are not a disease

How Do You Get Infected?

STIs are mainly spread through sex, whether it be vaginal, anal, oral or mutual masturbation. As well, some STIs can be transmitted through direct contact without having sexual intercourse, such as the sharing of sex toys.

Anyone who is, or has been, sexually active can have an STI. Many STIs do not have symptoms and can often go undetected without regular testing which means they can be unintentionally passed from partner to partner.

When Should I Get Tested?

Get tested regularly while sexually active, as well as if any of these risks apply to you. STIs need medical treatment because some STIs result in serious complications such as infertility, cancer or birth defects. Most STIs can easily be treated without complications.

  • You have unprotected vaginal, anal or oral sex
  • A condom breaks
  • Your partner has or had an STI
  • You or your partner injects street drugs
  • You have a new sex partner
  • You have had more than one partner in the past six months
  • Your partner has or had sex with another person
  • You have sex under the influence of drugs and/or alcohol
  • You are unable to communicate with your partner about your sexual history and ways to reduce risks
  • You are contacted by Public Health to say that you may have been in sexual contact with someone who has a reportable STI

Depending on the infection, your test results may not show any sign of the infection if your body has not had time to recognize it or make antibodies against it. For the majority of STIs, if testing is done less than 72 hours from exposure, the test results may not be accurate. Others, such as HIV, can take up to 12 weeks to detect

Types of STIs - Spreading the Word

Chlamydia- The "Silent" Infection

Did you Know... 50% of infected males and 70% of infected females do not have symptoms or are unaware of their condition?

How Is It Spread? Unprotected oral, vaginal, or anal sex with infected partner; infected mother to infant during birth

°  Male: penile discharge, testicular pain/swelling, penile itching

Screening: Easy and painless urine test (results in 7-14 days)


  • Antibiotics – 1 gram (single dose) of azithromycin
  • sex partner needs treatment

Treatment? No Cure- antiretroviral meds used to lower amount of virus in blood, reducing damage caused by virus and reducing risk of transmission allowing HIV to be managed like a chronic illness

Other Considerations: Spread by shared needles and sex. Even if you don’t have symptoms you can spread HIV to your sexual partners.

Myth-Busters: Armed with the Facts

MYTH: Condoms protect against all STIs.

FACT: Condoms do protect against STIs, but there are some infections, like genital herpes and warts, that can be transmitted by direct contact. If the condom does not cover the lesion it is not protecting you from the infection.


MYTH: I do not have any symptoms of an STI. Therefore, I do not have an infection.

FACT: A lot of STIs have no symptoms. Do not put yourself and your partner at risk. Get tested if you engage in risky behaviour.


MYTH: Washing genitals, urinating or douching after sex prevents STIs.

FACT: None of these methods are effective in preventing STIs


MYTH: You can only get an STI from vaginal or anal sex.

FACT:  You do not need to have sexual intercourse in order to get an STI. Some STIs are passed through oral sex or from other sexual activity.
