It is well known that poultry is highly susceptible to diseases. If an infection arises, it never is limited to one single bird, but will hit the entire flock. A dreaded example is highly contagious avian flu, officially named avian influenza, which strikes the poultry business across the globe time and time again.
An outbreak of avian flu or any other contagious disease can happen quite easily. Some of these have a period to survive of just hours to days, other may last much longer, up to even months.
An infectious and specifically zoonotic disease is not just harming poultry. It may also seriously impact human health. After all, poultry and poultry products end up in the food chain and thus may seriously impact the health status of food products from this origin.
