| A 73-year-old man presented to his local hospital with a 3-month history of inappetence and body weight loss. |
| The main clinical signs were depression, inappetence, huddling together, ataxia and recumbency. |
| Other observed clinical signs included bilateral serous ocular discharge, coughing with an increased respiratory rate, lethargy and inappetence. |
| In broilers, the signs of HPAI are frequently less obvious than for other poultry and usually include severe depression, inappetence, and a very marked increase in mortality may be the first abnormality observed. |
| However, alternatively the disease may appear suddenly in a flock and many birds may die either without premonitory signs or with minimal signs of depression, inappetence, ruffled feathers and fever. |
| In geese infected with the HPAI virus the signs of depression, inappetence and diarrhoea are similar to those in layers, though frequently with swollen sinuses. |
