2. ◦Infectious Laryngotracheitis (ILT):
A highly infectious disease of birds
of all ages caused by avian
herpesvirus I and characterized by
a very rapid spread of respiratory
distress. The mortality rate may
be as high as 70%

3. Vaccinal:
Associated with or having to
do with vaccine or vaccination

4. Avian Influenza:
A highly contagious disease
that affects the respiratory
tract, digestive tract, and
nervous system of many
species of birds. The mortality
rate can reach 90-100 percent
within 48 hours.

5. There are striking similarities between
ILT and Avian Influenza
Relatively short (3-10 days) incubation
Readily transferred on fomites
High mortality to susceptible birds
Disposition of dead birds
