Question:
AIDS
Answer:
VIRUS
Causative agent: HIV
Symptoms: pneumonia, Kaposi's sarcoma, weight loss, swollen lymph nodes,
loss of immune function
Prevention: safe sex practices, avoid sharing needles
Treatment: NRTIs, NNRTIs, PIs
,Question:
HIV progression of the levels of virus versus Helper T cells in the blood
Answer:
1. initial infection- high levels of the virus
2. virus numbers drop dramatically, antibodies appear, helper T cells decrease
3. long period of asymptomatic infection, number of T cells steadily
decreasing, eventually low enough to be considered AIDS
4. when AIDS occurs, antibodies are high but number of viruses increases
,Question:
HIV
Answer:
A virus that attacks and destroys the human immune system.
-infects CD4 T helper cells, crippling both antibody and cell-mediated
immunity
Question:
yeast infection/vaginal candidiasis
Answer:
FUNGUS
Causative agent: Candida albicans
Symptoms: itching & irritation of the vaginal area, white curd like discharge,
redness & swelling, burning sensation
Prevention: avoid unnecessary antibiotic use, good genital hygiene, avoid
harsh/scented soaps
Treatment: topical antifungal medications (clotrimazole) or oral antifungal
medications (fluconazole)
, Question:
syphilis
Answer:
BACTERIA
Causative agent: Treponema pallidum
Symptoms:
-> primary- chancre (painless ulcer), swollen lymph nodes
-> secondary- flu like symptoms (fever), skin rash (palms and soles)
-> latent- no symptoms, but still infectious if within a year, antibodies present
->tertiary- gummas (soft tumor like growth), neurosyphilis causes headaches
& personality changes, cardiovascular syphilis causes aneurysms
Prevention: safe sex practices, regular screening if at risk, prompt treatment,
avoid sex if in infectious stage
