front 1 continuation of last lecture (split into 2 lessons, but same powerpoint) | back 1 no data |
front 2 good news about HIV? what can be prevented? | back 2 transmission of HIV can be prevented |
front 3 initial phase of HIV infection: points of entry | back 3 female genital tract, male genital tract, intestinal tract, placenta, blood stream vagina, ectocervix, endocervix, inner foreskin, penile urethra, other, rectum, upper GI tract, chorionic villi medium of transmission: semen, cervicovaginal and rectal secretions and desquamations, maternal blood, genital secretions (intrapartum), breast milk, blood products, sharps |
front 4 HIV transmission | back 4 viral burden (or load) determine the chance of transmission
viral burden/load of HIV donor determiens chance of transmission (higher levels of virions donated = greater chance transmission will occur) |
front 5 is HIV transmission preventable? | back 5 yes start:
result
AZT reduced viral load = reduced viral load of transmission fluids (like those the baby is exposed to duing birth) = lowered chance of transmission ALL HAS TO DO WITH VIRAL LOAD!!!!!!!!!!! |
front 6 2 benefits of keeping HIV levels "suppressed) | back 6
|
front 7 at this point, only knew how to keep babies from getting it (see notecard #5) | back 7 no data |
front 8 PrEP | back 8 Pre-Exposure Prophylaxis (PrEP)
individual can start taking HIV drugs if not positive, do this so that if exposed to HIV, drug act agains few virions and attack virus when first enter body = does not go into acute phase (irreversible) all about stopping it before going into acute phase |
front 9 PEP | back 9 Post exposure prophylaxis (PEP)
|
front 10 therapeutic goal - eliminate HIV PRIOR to acute phase | back 10 "exposure to HIV" vs "HIV positive"
DISTINCTION: exposure vs perminanent infection
|
front 11 drugs so good, people good if they jsut remember to take them + be consistent | back 11 no data |
front 12 what HIV/AIDS research is being done now? | back 12 CDC main page
see links |
front 13 HIV testing | back 13 now have tests for drug resistance of HIV tells if person is infected w/ drug resistant strains and which drugs its resistant to as to avoid giving person those drugs |
