Ottawa
Comprises legal or fiscal controls, other regulation policies and voluntary codes of practice aimed at the enhancement of positive health and prevention of ill health
Health protection
Form of a logic model where assessment, intervention planning and evaluation are put into one framework
Precede proceed model
Phases of communicable disease
Pre pathogenic
Pathogenic
Elements of a communicable disease
Agent
Host
Environment
Ability of the agent to invade and multiply
Infectivity
Capacity of an agent to induce disease which is clinically apparent in an infected host
Pathogenicity
Ability of an agent to produce serious illness
Virulence
Ability of an agent to stimulate the host to produce defense mechanisms
Immunogenicity
Ability to combine specifically with the products or effectors of the immune response
Antigenicity
Type of carrier
Varicella, measles and hepatitis virus
Incubatory carrier
Type of carrier
Diphtheria
Hepa B
Convalescent carrier
Type of carrier
Salmonella
Hepa B
Chronic
Can be used to measure the rate of an epidemic
Period between the receipt of infection by the host and the maximal communicability of that host
Generation Time
Types of host
Parasite reaches maturity and if possible reproduces sexually
Definitive
Types of host
Can harbor a pathogen indefinitely without ill effects
Reservoir
Types of host
Harbors the parasite only for a short transition period during which some of the developmental stage is completed
Intermediate
Types of host
Host similar to intermediate but is not needed for developmental cycle to progress
Paratenic
Types of host
Level of pathogen can become high enough that a vector such as a mosquito that feeds on it will probably become infectious
Amplifying
Resistance of a group to invasion and spread of an infectious agent based on the immunity of a high proportion of individuals
Herd immunity
Refers to a time during which an infectious agent can be transmitted from a person to another
Period of communicability
Separates and restricts movement of people who were exposed to a contagious disease to see if they become sick
Quarantine
Exposure of a susceptible population to common source of pathogen
Common source outbreak
