Influenza Virus - Influenza is one of the viruses that spread.

In highly pathogenic avian influenza , the disease appears suddenly in a flock and many birds die either without premonitory signs or with minimal signs of depression, inappetence, ruffled feathers and fever. Other birds show weakness and a staggering gait. Hens may at first lay soft-shelled eggs, but soon stop laying. Sick birds often sit or stand in a semi-comatose state with their heads touching the ground. Combs and wattles are cyanotic and oedematous, and may have petechial or ecchymotic haemorrhages at their tips. Profuse watery diarrhoea is frequently present and birds are excessively thirsty. Respiration may be laboured. Haemorrhages may occur on unfeathered areas of skin. The mortality rate varies from 50 to 100%.

Vaccination
Inactivated quality assured oil-emulsion vaccines have been demonstrated to be effective in reducing mortality, preventing disease, or both, in chickens and turkeys. These vaccines, however, may not prevent infection in some individual birds, and if infected could shed virulent virus. Nevertheless, the amount virus shed is considerable less than that of non-vaccinated and infected birds. It is imperative that the circulating antigenic avian influenza virus is known and the vaccine represent this antigenic strain, since there is no cross-protection among the 15 known HA subtypes. A recombinant fowl pox virus vaccine containing the gene that codes for the production of the H5 antigen has recently been licensed in some countries but is not widely used currently. Homologous inactivated vaccines (H5N1) and heterologous inactivated vaccines (H5Nx) are the most commonly used.
