| 英文描述 | Equine influenza is a highly contagious respiratory disease. Sudden onset, rapid spread, usually worse in young animals. Outbreaks often a few weeks after horses are assembled in one place. Because there are antigenically distinct viruses and antigenic drift, there can be repeated epizootics in a short period of time. Dx by isolation, rise in titer, or immunoassay. Purulent nasal discharge indicates possible bacterial involvement. Lymph nodes of head may be enlarged. A mild form of myositis and myoglobinuria has been described in rare cases. |
