Field diagnosis

FIELD DIAGNOSIS
  • Based on clinical symptoms and lesions, vaccination history, prevalence of the infection in the area and age of the birds affected by the infection.
  • A flock will show very high morbidity with severe depression in most birds lasting for 5–7 days.
  • Mortality rises sharply for 2 days then declines rapidly over the next 2–3 days.
  • Usually between 5% and 10% of birds die, but mortality can reach 30–40%.
