Emergin disease and bioterror Flashcards
3 types of emerging disease
- newly emerging- not previously recognized in humans
- re-emerging - previosly recognized but in new places or greater #s
- deliberatly emerging - bioterrorsim
7 factors involved in emergence of disease
- microbial adaptations and change
- international travel and commerce
- intent to harm
- climate and weather
- economic dev. and land use
- breakdown of public health
- human susceptibility
factors involved in HIV (4)
- microbial adaptations and change
- international travel and commerce
- economic dev. and land use
- human susceptibility
def. seasonal flu
mild to moderate resp illness that may be associated with death
def. pndemic flu
- mild to moderate resp illness that may be associated with death
- higher attack rates
- fatality rate may be lower or higher
3 types of seasonal flu
ABC
1 type of avian/swine flu
A
what causes pandemic flu
Novel human influenza viruses formed from
adaptation of avian/swine/other animal influenza
viruses or recombination between
avian/swine/other animal influenza viruses and
human influenza viruses
what allows flu to recombine so easily
7 separate RNA segments that can be swapped
what was H1N1
quad combination of 2 swine, 1 avian, 1 human flus
what are H1N1 attack and death rates
attack - 14.5%
death - 0.5%
3 factors involved in pandemic flu
- Microbial adaptation and change
- Travel and commerce
- Human susceptibility to infection
what is SARS
febrile illness with 10% fatality rate
where did SARS come from
close proximity with civet cats in asia and then hong kong hotel
3 factors involved in SARS spread
- Microbial adaptation and change
- Travel and commerce
- Human susceptibility to infection
