Some viral diseases are host specific; others affect multiples species and age groups. • Failure to quarantine is the most common risk factor associated with viral disease outbreaks. • The presence of stressors such as poor water quality, poor husbandry practices, and overcrowding can increase susceptibility to disease. • Shared equipment between tanks and/or ponds can act as fomites and transmit disease between populations. • Negligent biosecurity practices in retail, wholesale, and aquacultural settings can increase the likelihood of viral outbreaks and mortalities on a large scale. Nonspecific. Viral diseases affect fish in cool water and warm water environments. • Most incubation periods and disease outbreaks of viral diseases are water temperature dependent. • Viral diseases can present acutely, peracutely, or as chronic conditions.
