An STI is a sexually transmitted infection mostly spread by sexual intercourse.

Slide 14 - Tekstslide

Write down two questions you have now about STI's. We will come back to these questions at the end of the class.

Slide 15 - Open vraag

How do you get an STI?

Slide 16 - Tekstslide

You can get an STI (or STD) from other people
  • Since these diseases commonly spread via sex, we call them  'sexually transmitted infections'
  • Most often, STIs come from bacteria, parasites or viruses.
  • Having unprotected (unsafe) sex is one way to get it, there are a few others

Slide 17 - Tekstslide

STD = sexually transmitted disease 

The term STI is preferred by scientists, but the term STD  is also used.  

Slide 18 - Tekstslide

Do you think you are able to prevent getting a STI? Explain your answer

Slide 19 - Open vraag

Except for not having sex, using a condom is the only way to really protect yourself from getting an STI

Slide 20 - Tekstslide

If you do decide to have sex how can you protect yourself?

Slide 21 - Tekstslide

0

Slide 22 - Video

Options you have in preventing STIs
- Limiting the number of sexual partners you have
- Getting tested frequently
- Talking to your partner about each others sexual history
- Avoiding drugs and or alcohol
- Educating yourself in what STIs there are and how you could get them

Slide 23 - Tekstslide

Options you have in preventing STIs
Latex barriers
    - Condoms
    - Internal/Female condoms
    - Dental Dam (oral sex)

Slide 24 - Tekstslide

How to get rid of STI's

Slide 25 - Tekstslide

STIs can be bacteria, parasites and viruses
- Antibiotics (against bacteria, sometimes parasites)
Often in a single dose, can cure many sexually transmitted bacterial and parasitic infections

- Antiviral drugs (against viruses)
If you have herpes or HIV, you'll be prescribed an antiviral drug.

Slide 26 - Tekstslide

However, there is one problem!
  • You can not get rid of every STI. Some STIs you can treat and they won't bother you, but they will remain in the body and come back as a disease when your immune system is not working properly (for instance when you get a cold). 
  • The two most well-known permanent STIs are HIV and Herpes.
  • Herpes can present on different parts of the body, the most common one being on the lips (koortslip). You can get this lip-version from drinking out of someones glass!
  • HIV is much more difficult to get! A simple condom can prevent that.

Slide 40 - Tekstslide

HIV and AIDS

Slide 41 - Tekstslide

HIV
  • HIV is the most well known STI because it can cause lots of problems
  • HIV affects the immune system, which makes it easier to get other problems (lung infections etc)
  • Eventually, the immune system would not work anymore. If we get to that point, we call the disease AIDS 
  • People with AIDS do not have long to live, people with HIV can live for a very long time (if treated correctly)
AIDS = Acquired ImmunoDeficiency Syndrome

Slide 42 - Tekstslide

AIDS
  • AIDS is caused by HIV, so you can call HIV the AIDS-virus
  • Someone could be infected with HIV, but not feel sick. That's what you call seropositive.
  • Most people infected with HIV also get AIDS. This can take years.
  • The 'Red Ribbon' is the international symbol for people with HIV/AIDS.

Slide 43 - Tekstslide

Slide 44 - Video

Slide 46 - Quizvraag

Slide 47 - Open vraag

What do you do if you think you have an STI?

  • An STI never goes away on its own! 
  • Even without symptoms you can be sick
  • Go to your doctor, GGD or Centrum Seksuele Gezondheid, They can treat you anonymously!
  • Take an STI-test
  • A STI-test doesn't hurt (often it's a urine test or smear test).
Smear test = uitstrijkje
