english: One example is avian influenza, where we can abolish it in farmed animals, in turkeys, in ducks, but it keeps coming back every year because it's brought to us by wild birds.
non_english: Jedan od primera je ptičji grip, koji možemo da uništimo kod domaćih životinja, kod ćurki, patki, ali on se stalno vraća svake godine jer nam ga donose divlje ptice.
