Principles of Prevention and Control Flashcards
What is disease PREVENTION
proactive approach to maintain the health of animals PRIOR to exposure
what is disease CONTROL
the action taken to prevent new cases of disease and limit impact after disease is detected
What factors contribute to health and disease? (4 main things)
nutrition
immunity
environment
genetics
what do genetics determine from a health aspect
determine baseline resource needs and how they are allocated
What do nutrition and environmental aspects determine?
how many resources the body has
what does immunity determine
supports response to pathogen exposures and determines susceptibility or resistance to disease
what is epigenetics?
the study of how the environment can cause changes in how genes are expressed
how is herd immunity accomplished? (3)
- natural exposure
- controlled exposure
- vaccination
What is transmission rate?
TR= contact rate (host enviro interaction) X infectivity (probability of infection given contact)
Determines HOW many cases you will see
how does long term stress affect disease
induces continued corticosteroid response and disrupts homeostasis and energy balance, which decreases pathogen resistance
define biosecurity
a set of management and physical measures designed to reduce the risk of introduction, establishment, and spread of animal disease to, from, and within a population
When you know disease is detected, what factors are importing in determining context (4)
- primary underlying cause
- population
- resources
- policies
what is the goal of primary strategies?
to prevent NEW cases and interrupt transmission BEFORE infection occurs
what is the goal of a secondary infectious disease control strategy?
to detect new cases as EARLY as possible and reduce risk of further transmission
what is the goal of a tertiary infectious disease control strategy?
medical treatment to prevent the worst outcomes of a disease in an individual or population. DISEASE MITIGATION
