group 1 Flashcards
Series of events that occur because of the interaction between an infectious agent I host and their environment
Chain of infection
This includes bacteria viruses fungi and parasites
Infectious agents or pathogens
This is the ability to produce disease
pathogenicity
this is the ability to spread
Transmissibility
This is an object or service that is capable of transmitting diseases and infectious agents referred to as passive vectors
fomite
It does not show signs or symptoms of infection or illness does disease can you spread unknowingly
A symptomatic or passive carriers
This transmit infectious agents before they experience symptoms of infection themselves
incubatory carriers
These are who have experience illness and are still able to transmit it to others
Convalescent carriers
These are capable of transmitting infection to others for months or years after they first become infected
Chronic carriers
They are less likely to spread disease as they are aware of the risk they post to other people
Symptomatic carriers
This is where the infectious agent leaves gross and proliferates
Reservoir
This transmission from animal to person
Zoonosis
It refers to the path through which an infectious agent leaves I host
Portal of exit
It refers to how an infectious agent can be transferred from one person, object, or animal to another
Mode of transmission
Factors that lower the risk of infection
The skin, mucosal membranes, gastric acidity, cough reflexes, non-specific immune responses
