Symptoms in Birds:
Avian influenza is an infectious disease of birds caused by type A strains of the influenza virus. The disease occurs worldwide. While all birds are
thought to be susceptible to infection with avian influenza viruses, many wild bird species carry these viruses with no apparent signs of harm.
Other bird species, including domestic poultry, develop disease when infected with avian influenza viruses. In poultry, the viruses cause two
distinctly different forms of disease – one common and mild, the other rare and highly lethal. In the mild form, signs of illness may be expressed
only as ruffled feathers, reduced egg production, or mild effects on the respiratory system. Outbreaks can be so mild they escape detection unless
regular testing for viruses is in place.
In contrast, the second and far less common highly pathogenic form is difficult to miss. First identified in Italy in 1878, highly pathogenic avian
influenza is characterized by sudden onset of severe disease, rapid contagion, and a mortality rate that can approach 100% within 48 hours. In this
form of the disease, the virus not only affects the respiratory tract, as in the mild form, but also invades multiple organs and tissues. The
resulting massive internal haemorrhaging has earned it the lay name of “chicken Ebola”.

So in other words HSN1 has the same effect and symptoms in poultry as worms and Coccidiosis which has always existed? No new real effects shown in
birds as cocci can drop birds dead within 24-48 hours.
Effects in humans:
* Fever
* Sore throat
* Muscle aches
* Headache
* Lethargy
* Conjunctivitis (eye infections)
* Breathing problems
* Chest pains
The same symptoms people get from the "common flu" every year?
