8C - Controlling Pathogen Spread Flashcards
serology
The study of blood serum, typically to determine the presence of antibodies and/or antigens.
serum
The fluid and solute component of blood that excludes blood cells, platelets, and clotting factors.
enzyme-linked immunosorbent assay (ELISA)
An experimental technique used to identify a pathogen by determining the presence of antigens or antibodies in a sample.
host
An organism that harbours a pathogen.
transmission
The passing of a pathogen from an infected host to another individual or group.
airborne transmission
The spread of pathogens through air via small particles (traditionally <5 nano metres)
droplet transmission
The spread of pathogens through air and contaminated surfaces via respiratory droplets
respiratory droplets
Droplets (traditionally >5 nano metres) produced by breathing, talking, vomiting, and coughing. They may contain saliva, mucus and other substances from the respiratory tract, including cells/ particles of pathogens.
direct physical contact transmission
The spread of pathogens through contact between a host and another individual.
vertical transmission
Spread of pathogens from mother-to-child during gestation, during childbirth or post-birth due to close physical contact and breastfeeding of a newborn.
iatrogenic
Describes a disease caused by medical intervention.
indirect physical contact transmission
The spread of pathogens via contaminated objects or vectors.
fomites
An inanimate object that, when contaminated with a pathogen, can transmit that pathogen to a new host.
vector
An organism that is not affected by a disease but spreads it between hosts.
faecal-oral transmission
The spread of pathogens via oral consumption of contaminated faeces.
