Download Day 9 Bacterial and Viral STDs - Answer Sheet

Sexually Transmitted Diseases – Day 9
Objective:
Students will be able to identify the cause, symptoms, mode of transmission, treatments/cures, and
prevention for the top ten sexually transmitted diseases.
Question: Which do you think is worse, a sexually transmitted disease caused by a
bacterium, a parasite, or a virus? Explain your choice.
REFLECT upon your hypothesis from the previous lesson. Do you still feel your hypothesis is the best prediction for
the question posed? If yes, then what new information from the previous lesson lends support for your hypothesis?
Explain below. If not, then re-write your hypothesis below and discuss what new evidence prompted you to change your
hypothesis.
Student answers will vary – just be sure that students support their hypothesis with information
gained from the previous day’s lesson regarding the sexually transmitted diseases covered.
Be sure to point out that it is perfectly acceptable to modify (rewrite) their hypothesis based
upon new evidence / information.
Inform Yourself! Using the resources provided by your teacher, complete the following data table.

Put Your Knowledge to the TEST: Choose 2 out of the 3 patients from the table below and based upon the symptoms
presented, diagnose what STD s/he has, provide evidence for your conclusion (diagnosis), and list the possible
treatment(s).
Patient
#1
Symptoms
Presented
Male patient has a
skin rash on chest and
hands and feet;
patient has a fever
and complains of
headaches and
fatigue; upon
questioning, patient
admitted to having a
chancre sore on
genitalia that lasted
for weeks a while
back
Diagnosis
SYPHILIS
Evidence for
Diagnosis
Primary Stage:
chancre sore on
genitalia
Secondary Stage:
skin rash on chest and
hands and feet; fever;
headaches; fatigue
Treatment
CONSULTATIONS
(Need FOUR signatures per
patient)
BLUE INK = AGREE
RED INK = DISAGREE
Single, perhaps
multiple
intramuscular
injections of
penicillin (or
other antibiotic)
#2
#3
Female patient has
had abdominal pain
and nausea for about
4 days; she is running
a slight fever and
admits that she has
noticed a vaginal
discharge and sexual
intercourse has been
painful; she is
reluctant to give a
urine sample because
she says it hurts when
she urinates
abdominal pain;
nausea; fever;
CHLAMYDIA abnormal vaginal
discharge; painful
sexual intercourse
Female patient has
had flu-like
symptoms for about a
week; lymph nodes
are swollen and upon
a physical inspection
several blister-like
sores on her genitalia;
patient admits that
this is not the first
time she has had
those sores appear
HERPES
(GENITAL
HERPES)
[HSV-2]
flu-like symptoms;
swollen lymph nodes;
repetitive blister-like
sores on genitalia
Antibiotics
[possible single
dose of
azithromycin or
a weekly dose of
doxyxycline
(two time daily)]
NO CURE
Antiviral
medications can
shorten and
prevent the
outbreaks (of
sores); daily
suppressive
therapy can help
prevent
transmission to
other partners
Check Your OWN Understanding: You now need to CONSULT with other professionals. For each patient you chose,
find 4 other physicians that also diagnosed that particular patient and get their signature in BLUE INK if they agree with
your diagnosis and RED INK if they disagree with your diagnosis.
Putting It ALL Together: Pick one patient from above and explain how they got the disease and how they might
prevent contracting STDs in the future.
