Flashcards in Preventative Care Strategies 2 Deck (41):
the reservoir of an infectious agent is the habitat in which the agent normally lives, grows and multiples
removing infected individuals
infection may be removed from a herd by testing and slaughtering those found to be infected
usually restricted to a local situation in which all potentially infected animals or people are treated without first testing them to identify infected individuals
what is the risk of mass therapy?
development of resistant strains and adverse side effects of therapy
a method of reservoir neutralization designed to break the chain of transmission between the portal of exit of the infected (shedder) host and the susceptible host by reducing survival of the agent in vector or vehicles (food, water, soil, vegetation)
use of natural enemies to manage mosquito populations, such as predatory fish that feed on mosquito larvae
insecticides that specifically targets the larval stage of mosquitoes
insecticides against adult mosquitoes
applies to animals/persons who are known to be ill with contagious disease
applies to those who have been exposed to a contagious disease
protection of portals of entry
personal protection: protective clothing, repellents, nets on doors and windows, mosquito nets
use of antimicrobial drugs
what is the "where" of immunization?
primarily populations in endemic areas
what is the "when" of immunization?
if the disease has a distinct "season", such as seen with Vector-borne agents, immunization just before the season will provide the maximum efficiency; outbreak of an nonendemic disease occurs
what is the "who" of immunization?
population at risk
what is the "why" of immunization?
for a program of vaccination to be justifiable, the loss caused by the disease must be greater than the cost of immunization
form of immunity that occurs when the vaccination of a significant/large portion of a population (or herd) provides a measure of protection for the small number of individuals who have not developed immunity
OIE steps for establishing a disease control program
establishing rationale, strategic goal and objectives, program planning, implementation, monitoring, evaluation and review
World Animal Health Information Database

have unique resources to handle highly infectious agents and the ability to identify specific agent strains
can perform tests to detect and confirm the presence of a threat agent. These labs ensure a timely local response in the event of a threat incident
represent the thousands of hospital-based labs that are on the front lines. They have direct contact with patients
differentiating infected from vaccinated animals
facilitates the identification of affected animals, herds, or flocks
premises where a presumptive positive case or confirmed positive case exists based on laboratory results, compatible clinical signs, case definition, and international standards
premises with susceptible animals that may have been exposed to the FAD agent, either directly or indirectly, including but not limited to exposure to animals, animal products, fomites, or people from infected premises
zone that immediately surrounds an infected premises
zone that immediately surrounds an infected zone
consists of an infected zone and a buffer zone
zone outside and along the border of a control area
area not included in any control area
emergency vaccination zone classified as either a containment vaccination zone (typically inside a control area) or a protection vaccination zone (typically outside a control area) this may be a secondary zone designation
transmission of infectious diseases from animals to humans
what is included in the one health triad?
healthy people, healthy environment, healthy animals
the global early warning system for major animal diseases including zoonoses
