Which poultry disease is of particular concern for high mortality rates?

Avian Influenza is particularly concerning due to its potential for high mortality rates among poultry. This disease can lead to severe outbreaks and significantly impact flocks, causing widespread death in affected birds. The virus can mutate rapidly, and certain strains can be highly pathogenic, meaning they cause rapid and severe illness. In some cases, mortality can be as high as 90% within affected populations, making it a serious threat to the poultry industry. Furthermore, Avian Influenza can be transmissible to humans under certain circumstances, which adds to its overall public health significance.

While the other diseases listed can also affect poultry, they typically do not present the same level of mortality risk as Avian Influenza. For instance, Newcastle Disease can have severe impacts, but not all strains result in high mortality rates. Infectious Bronchitis primarily affects the respiratory system and typically does not lead to the same level of mortality, while Coryza is generally less severe. Therefore, Avian Influenza stands out due to the potential for rapid spread and high death rates in infected flocks.
