Clinical Signs: 
conjunctivitis, nasal discharge, coughing, sneezing
Clinical description: 
The IB virus is shed in the nasal excretions and feces of infected birds. In production facilities such as this one, the virus typically spreads quickly from bird to bird, via direct contact with contaminated feed, water, equipment, and infected birds. In some birds, internal organs become persistently infected, resulting in intermittent shedding of the virus. These persistent carriers increase the possibility of flock-to-flock spread of the virus via unknowingly contaminated personnel.
