Disease control strategies

Question 1

STRATEGIES FOR CONTROL OF

DISEASE (know 5)

Answer 1

 Doing nothing (e.g. relying on endemic stability)
 Quarantine (e.g. rabies quarantine for dogs)
 Slaughter (e.g. FMD, tuberculosis, brucellosis,
BSE, mastitis)
 Vaccination
 Therapeutic and prophylactic chemotherapy (e.g.
anthelmintics, prophylactic feed medication,
prophylactic use of antibiotics)
 Control movement of hosts (e.g. African horse
sickness, trypanosomiasis, fascioliasis,
babesiosis)
 Mixed, alternate and sequential grazing
 Control of biological vectors (e.g. tsetse, Limnea
truncatula. Condemnation of meat containing
cysticercus bovis cysts)
 Control of mechanical vectors (personal hygiene,
cleansing and disinfection of cattle lorries etc.,
foot baths and wheel washes)
 Fomite disinfection (food-borne infection, heat
treatment, prevention of iatrogenic transmission)
 Improvement in environment, husbandry and
feeding (e.g. control of mastitis, neonatal
mortality)
 Genetic improvement removal of a genetic
defect, genetic screening (e.g. scrapi, Mareks’
disease)
 Minimal disease methods (SPF animals)
