during the last 2 decades & threaten to increase in the future
reemerging diseases - ANSWER diseases previously controlled by antibiotics but
developed resistance and are appearing in epidemic form
unplanned & underplanned urbanization
overcrowding/rapid growth
poor sanitation
inadequate public health infrastructure
antibiotic resistance
increased exposure
rapid international travel
immunosupressed - ANSWER factors responsible to emerging and reemerging
diseases
animals --> humans
increased transmission s/t to increased close contact of animal and human
deforestation, climate change, large scale farming, food processing, change in societal
norms, decreased vaccinations, increased travel and trade - ANSWER zoonotic
