12.3 The transmission of communicable diseases Flashcards
what are the types of transmission of pathogens between animals?
direct transmission
indirect transmission
types of direct transmission in animals
direct contact
inoculation
ingestion
direct contact
sexual intercourse
direct skin-to-skin contact
kissing
exchange of fluids
inoculation
through a break in the skin
from an animal bite
through a wound
ingestion
eating contaminated food or drink
types of indirect transmission in animals
fomites
droplet infection
vectors
fomites
transmission through objects like bedding and socks
droplet infection
when you talk, sneeze or cough droplets are released
droplets may contain pathogens
vectors
transfers communicable disease from one organism to another
what factors increase the chance of the transmission of a pathogen?
overcrowded living
poor nutrition
weakened immune system
poor disposal of waste
climate change
culture
lack of trained healthcare workers
direct transmission in plants
direct contact between a healthy and diseased part
types of indirect transmission in plants
soil contamination
vectors
soil contamination
diseased plants often leave pathogens in the soil
the next crop to be placed in the same soil will be affected
types of vectors in plants
wind
water
animals
humans
how is wind a vector in plants?
spores can be carried in the wind
