Why do you need to know about
STIs?
 The average age both male and female Canadians have
sex for the first time is 16.5.
 28% of teens aged 15-17 report having had sexual
intercourse at least once. By age 20-24, this increases
to 80%.
 In a 2005 report, 41% of males aged 15-17 and 39% of
those aged 18-19 reported having more than one sexual
partner in the previous year.
 For females in the study, 29% of 15-17 year olds and
31% of those aged 18-19 reported having more than
one sexual partner in the previous year.

What is an STI?
 Sexually transmitted infections are
infections usually transmitted through
sexual intercourse.
 STIs often do not have any symptoms; it
is possible to have an STI and not even
be aware of it.
General Warning Signs





different vaginal discharge
discharge from penis
burning during urination or sex
sores or growths on genitals or around anus
itch or odour
Any STI…
 can increase chances of getting another STI.
 can be passed from the mother to the baby during the
birthing process.
 may lead to infertility in women.
What causes STIs?
 bacteria
 viruses
curable with antibiotics
easily cured if caught
early; however, there
are often no symptoms

eating
utensils
holding

STIs are NOT transmitted via…
bedding
swimming
pools
telephones

bites
How are STIs transmitted?
sharing/using dirty
needles
sexual
intercourse
(anal, vaginal, oral)

Common STIs
 bacterial:
 chlamydia
 gonorrhea
 syphilis
 viral:
 HIV
 human papillomavirus/genital warts
 hepatitis
Chlamydia & Gonorrhea
 chlamydia: up to 90% of women and 70% of men with chlamydia
have no symptoms
 gonorrhea (‘The Clap’): 80% of women & 40% of men with
gonorrhea have no symptoms
 common symptoms:
- discharge from penis/vagina
- painful urination and bowel movements
- painful intercourse
- in women: bleeding between periods, bleeding after intercourse
 Symptoms usually appear a couple of days to a few weeks after
infection.

Updated October 2013
Chlamydia
 can easily be treated with a single dose of antibiotics
 a significant cause of blindness
 passed through vaginal/anal sex, but not usually through
oral sex
Gonorrhea
 can be treated with antibiotics
 arthritis
 pelvic inflammatory disease
Syphilis
 several stages of infection:
 primary
 3 weeks to 3 months after infection
 chancres on genital area—painless and VERY
contagious
 secondary
 2-3 months
 spotty skin rash
 fever, fatigue, hair loss
Syphilis
 chronic
 period of no symptoms
 may continue for years!
 may progress right on to tertiary
 tertiary
 serious organ damage occurs anytime after one year
 affects eyes, brain, muscles  can be fatal
Updated March 2008
Syphilis
 infection can be spread to fetus in pregnant women and
cause stillbirth or lifelong disabilities
 fetal abnormalities  prenatal care!
 treatment:
 infection <1 year long: a single shot of penicillin
 infection >1 year long: many doses of penicillin over three weeks
Human Papillomavirus
 HPV can lead to genital warts in the genital or anal areas
 #1 cause of cancer of the cervix
 symptoms:
- genital warts (cauliflower-like)
- often recurrent and resistant
- up to 90% of people have no symptoms (self-heal within 2
years)
 extremely common, with up to 80% sexually active people
being infected
 newborn babies rarely get the virus during the birthing process
Human Papillomavirus
 diagnosis of HPV done using the Pap smear
 once sexually active, females need yearly Pap smears
 symptoms (genital warts) can be treated, but there is no
cure
Human Papillomavirus
 protection: females are vaccinated between the ages of
9-26 (up to age 45 in women at high risk)
 Gardasil®:
 offers protection against cervical cancer and genital
warts
 given as 3 injections over 6 months
 covers 4 out of 6 HPV viruses that can cause cancer
(70% of cervical cancer and genital warts)
 Speak to a health care professional about whether
you should receive it.
Herpes
 symptoms can occur 2-10 days after exposure
 may show no symptoms
 can cause itching, blisters/sores, pain/discomfort of
genital area, difficulty or pain in urinating
 estimated 1/7 Canadians aged 14-59 have herpes
 estimated only 1/10 of those know they have it
Herpes
 symptoms can be treated, but herpes cannot be cured
 may be passed on to partners at any time
 viral shedding occurs even when blisters are absent
 pregnant women should be tested
 herpes can be passed on to unborn child, causing
disability or miscarriage
Herpes
 recurrent episodes are usually shorter and less severe
 people have on average about four outbreaks per year
 stress and anxiety are common triggers for outbreaks
HIV/AIDS
 True or False?
 Only MSMs, sex trade workers, and people in third
world countries can get HIV.
 There is a cure for HIV.
HIV/AIDS
 HIV = Human Immunodeficiency Virus; AIDS = Acquired
Immune Deficiency Syndrome
 HIV is a virus that attacks the immune system; an HIV
infection can progress to the AIDS syndrome
 HIV may have no symptoms, or mild symptoms; AIDS
patients can have life-threatening infections or cancer
HIV/AIDS
 an estimated 70 000 people have HIV in Canada; 2500 new
cases each year
 HIV infection increases chances of getting another STI, and
vice versa
 can be passed from a mother to baby through breast milk or at
birth
 There is no cure for HIV!
Hepatitis





hepatitis = inflammation of the liver
many types of hepatitis; most common are A, B, C
diagnosed via simple blood tests
vaccines available for Hepatitis A & B
each one is transmitted a bit differently:
 A - fecal/oral
 B - blood and body fluids
 C - blood products
 Hepatitis A & B symptoms: flu-like symptoms, darker
urine
 Hepatitis C symptoms: extreme fatigue
 may have no symptoms
Other ways to get HIV and
hepatitis
 IV drug use (20-40% of IV drug users are infected with
hepatitis C within the first year, and up to 90% after 5
years; can also get HIV from IV drug use)
 tattoos
 Prevention!
 Don’t share needles, syringes, and other drug
paraphernalia.
What should I do if I suspect I
have an STI?
stop having sex
get tested at a doctor’s
office or clinic
treat your partners as
well
Preventing STIs
abstinence: the only 100% way of preventing the
spread of STIs
mutual monogamy: limiting sex to one uninfected
partner who only has sex with you
It’s a good idea to ask your partner if she/he has an
STI and work out a risk reduction plan.
Preventing STIs
Do not use/share needles with anyone.
Use a condom during intercourse; this can drastically
decrease the chances of getting an STI. (N.B. Proper
use is EXTREMELY IMPORTANT!)
Other birth control methods: the pill, diaphragms,
spermicide—do those prevent STIs?
Test and treat for STIs as quickly as possible.
Condom Disclaimer
Condoms are not 100% effective against
infections that can be transferred from skin
to skin contact (i.e. herpes, HPV).
Condom Dos and Don’ts
 Do store in a cool dry place.
 Do not leave condoms in the sunlight, a wallet or glove
compartment.
 Do check the expiry date.
 Do use a water based lubricant (e.g. KY Jelly®).
 Do not use oil-based product (e.g. Vaseline®).
Condom Dos and Don’ts
 Do open a package carefully.
 Do not open with teeth or scissors.
 Do not use spermicide with condoms; it may cause
vaginal irritation or cause latex to break down.
 Do practice putting on and taking off the condom.
 Do read the instructions carefully.
