b.stev Epidemiology animal disease

TRANSMISSION of DISEASE DIRECT CONTACT – touch : wounds mucous membranes skin with blood/ bite / rub nose to nose contact Pathogenic MICROBES infect a population of animals in a number of different ways OUTBREAK : analysis of the transmittance LISTED :

DIRECT CONTACT – touch :

wounds

mucous membranes

skin with blood/ bite / rub

nose to nose contact

AEROSOL – droplets passed (cough/ sneeze/ urine) ORAL – object contamined (H 2 O/ feed/ licking/ chew) REPRODUCTIVE – mating & foetus TRAFFIC – vehicle/ trailer carries infection VECTOR BORNE – insect passes disease ZOONOTIC – carried: animal to human ENVIRONMENT – habitat is considered FORMITE – an object passes from animal-animal (Iowa State University, 2008)

AEROSOL – droplets passed (cough/ sneeze/ urine)

ORAL – object contamined (H 2 O/ feed/ licking/ chew)

REPRODUCTIVE – mating & foetus

TRAFFIC – vehicle/ trailer carries infection

VECTOR BORNE – insect passes disease

ZOONOTIC – carried: animal to human

ENVIRONMENT – habitat is considered

FORMITE – an object passes from animal-animal

TRANSMISSION over large areas in a very short TIME can occur: MODERN TRANSPORT DEPENDENT of DISEASE PROPERTIES: TIME may lapse: 6/ 8 weeks OR much more before indication of the disease becomes obvious & diagnosis confirmed

OUTBREAK : a disease occurs more than expected in a time frame to a specific area EPIDEMIC : disease appears substantially more times than expected in a time frame at different locations – strains may vary. PANDEMIC : an outbreak is diagnosed over countries OR continent/s – strains may vary WHAT is AN (Wikipedia, 2008)

SURVELLIANCE: records must be kept immunisation plans inoculation of animal/s quarantines performed migration of animal/s occurrence of disease - source of infection - treatment method

SURVELLIANCE:

records must be kept

immunisation plans

inoculation of animal/s

quarantines performed

migration of animal/s

occurrence of disease

- source of infection

- treatment method

areas of the DNA contain ,codes, that would differ if it is not a certain strain HOW IT IS DONE: Different STRAINS of a disease can be identified by the use of their DNA This is called: TYPING METHOD (Wikipedia, 2008) process: HOW > disease has spread & it’s origin can be better determined

INTERVENTION inform citizens & parties that require notification: prevention measures that can be taken signs to observe in the animal/s disregard all intended stock movement if possible : inoculation and quarantine inspection & advice – VETINARIRIAN

inform citizens & parties that require notification:

prevention measures that can be taken

signs to observe in the animal/s

disregard all intended stock movement

if possible : inoculation and quarantine

inspection & advice – VETINARIRIAN

NOTES on DISEASE: RISK to ALL health - till diagnosis LOSS in production NOT always preventable cause of EMOTIONAL stress COST in time/ money/ action TIME required to replenish CAREFUL observation at all times contact the VET ; if in doubt

RISK to ALL health - till diagnosis

LOSS in production

NOT always preventable

cause of EMOTIONAL stress

COST in time/ money/ action

TIME required to replenish

CAREFUL observation at all times

contact the VET ; if in doubt
