It is destroyed by common disinfectants, dry environment, and sunlight. What is the drug of Coryza? While the greatest economic loss related to Infectious Coryza results in poor egg production (marked reduction 10-40%) in layer and poor growth performance in growing chickens it can cause mortality especially in stressed or already weakened birds. If the disease is not endemic in a given area for infectious coryza, depopulation may be used to decrease the likelihood of passing the disease to future flocks. For instance, in cases where a person experiences sinusitis or rhinitis, a person may take antibiotics, antihistamine if there are allergies and even nasal irrigation.
