    chlamydia, HPV, and herpes

Chlamydia

A

Symptoms:

  • Penises = 50% asymptomatic, thin, clear discharge, mild discomfort on urination
  • Diagnosis = urine sample
  • Vaginas = 75% asymptomatic, abnormal vaginal discharge, itching, burning, pain with urination

  • Consequences if left untreated: Pelvic inflammatory Disease(for women), Epididymitis (for men) - not as severe

both can result in infertility

-is increasing

Q

Syphilis

A
  • 4 stages:

Primary stage
* chancre(it goes away by itself)

Secondary stage
* body rash: dosent hurt (goes away)

Latent syphilis
* it can last years

  • no symptom
  • the bacteria is going through tissues of the body brain,spinel cord,bones
  • not able to pass on anybody anymore (except pregnant women can pass on to the fetus)
  • half of the people would stay in this stage their whole lifes the other half would go to the next stage

Late syphilis(serious affects)
* major effects in the cardio vascular system: heart and major blood vessels are attacked by the bacteria

  • brain and spinal cord can be attacked which can produce cognitive issues
  • 40 years after the initial infaction occurs

Congenital Syphilis:
* present from birth
* can cause miscarrage
* severe illness after birth
* can cause complication that show up 10 to 20 years later

Q

Syphilis

A

Diagnosis:
* Difficult to diagnose(the chanquer is not always apperant and the rash can appear to be something else)

  • Genital or pelvic exam, full body exam, blood tests

Treatment:
* Penicillin shot

Q

HPV: Human papillomavirus

virus

A
  • More than 40 different types that cause genital warts & cancer
  • Types 6 and 11 cause genital warts are associated with cancer
  • Non-reportable, so no national Canadian data:

physicians dont need to send a report to bc center desease control so is difficult to know the actual rates are

Q

HPV

A

Symptoms:
* 90% asymptomatic

Diagnosis:
* Inspection of the warts

Treatment:
* Creams, freezing

even if u dont have warts you still can carry and spread HPV

it can become undetective after 2 years

even if u are treated from one u can still have from other streams

Q

Psychological Impact of Herpes

A

Range of responses:

  • STI-related stigma - awarness that people that contract sti are judged negatively
  • STI-related shame- negatively judgeging themselves from having stis
  • Better outcomes for those who have fewer outbreaks
  • Foster & Byers (2016)
    -people with more self-estigma and self-blame is associated with poorer outcomes

-most people are able to ajdjust pretty well after getting a diagnose , with a healthy sexual life

Q

HIV & AIDS

virus

A

Origin: virus crossed from primets to humans most likely when people butchered primats for meat, they might have cutted themselves and in the process the virus got in the bloodstream

  • 1981 – first identified in USA
  • 1982 – first case in Canada
  • 1984 – HIV was identified
  • Currently – a global pandemic
    -most people dont know they are infected

-72% accurse in africa

  • Only 46% have access to treatmen
  • there are 2 streams of HIV (HIV 1 more in north america, HIV2 in africa)
  • demages the imune system
16
Q

Transmission:

A
  • Exchange of bodily fluids (semen, vaginal secretions, blood, breast milk)

In Canada new cases in the following groups:

  • Men who have sex with men (54%)
  • Heterosexuals who have sex with infected person (19%)
  • Heterosexuals who came from AIDs epidemic country (14%)
  • People who inject drugs (13%)

Highest risk behaviours:
* Anal intercourse
* Vaginal intercourse

because they are most likely to cause tearing and allow the virus to infect the blood stream of the other person

17
Q

4 stages of HIV infection:

A
  1. Primary/acute infection – 2-4 weeks after exposure; nonspecific symptoms (like a flue) or no symptoms
  2. Chronic asymptomatic infection – virus replication; nonspecific symptoms(fever,swolen nose) or no symptoms
  3. Chronic symptomatic HIV infection – virus has reduced T4 cells, body is not able to fight off infections; non-specific symptoms(fever,yeast infection,weight loss)
  4. AIDS-defining conditions – life threatening opportunistic infections take over
    (pneumonia, Kaposi’s sarcoma - skin cancer)
18
Q

Diagnose and treatment

A

Diagnosis – blood test:
* ELISA: tests antibodies (some false positive)

  • Western blot (rare false positives)
  • Rapid 60 second test
  • Home test kit(not as reliable)

Treatment

  • No cure
  • HAART: antiviral drugs -supress the virus and if u take it right can live for 20 years but causes a lot of side effects
  • Adherance
19
Q

Psychological Impact of HIV/AIDS

A
  • Socially stigmatized disease
  • Depression
  • Impact on sexual life(afraid to pass to others)
20
Q

HIV & AIDS

A
  • Challenges in developing vaccine(HIV has many forms)
  • Preexposure prophylaxis (PrEP): antiviral for protection, stops the viral from spreding through the bodies (what caio takes)
  • Genetic resistance: some gene mutation. jus 1% have this and 10% of europeans maybe because they survevide the berbalutic plague
21
Q

Trichomoniasis

parasites

A
  • “Trich”
  • can survive in surfaces like toilet seats(not very common to be transefered this way)
  • Caused by Trichomonas vaginalis
  • Symptoms:
  • Vaginas = vaginal discharge
  • Penises =** irritation of the urethra, discharge**

often not sintemetic

  • Diagnosis:
  • Urine sample or sample of vaginal fluid
  • Treatment:
  • Metronidazole or tinidazole
22
Q

Pubic Lice: crabs

parasite

A

can be spreed during sex, badsheets and hard surfaces

Symptoms:
* Intense itching

Diagnosis:
* Find lice & eggs

  • Treatment:
    * Nix, Rid(things that kills lice)
23
Q

Reportable STIs

A

when u go to the physician they will let the public health know so they can track how is spreding in the population. the doctor needs to let the partners know they might have the deasses

  • Syphilis
  • Gonorrhea
  • Chlamydia
  • HIV

why these ones?
* is not curable
* might cause infertility
* it might cause pelvic infection

who dont need to

  • herpeas
  • HPV
24
Q

Prevention

A
  • Latex condoms(not perfect blisters from HPV can be in other parts of the body)
  • Dental dams (might touch other areas not protected by the dam)
  • Washing genitals before sexual activity (helps kill bacteria but does not do much for sti)
  • Urinating before and after (is good to kill bacterias but not necessarly stis)

best to: get regurlaly tested and approch using condom and how to respond if they want to do it without it.
