Avian influenza caused by influenza A virus, H5N1 subtype, has been popping up regularly in the news in the last few years because of fears that it might evolve into a form that would lead to a pandemic among humans. The DDC medicine schedule does not make fine distinctions based on the type of virus nor on the origin of the virus; rather, it treats all influenza in a particular animal the same.
Works about efforts to prevent the spread of avian influenza among domestic poultry (such as programs to vaccinate chickens, to prevent wild birds getting into poultry houses, culling infected flocks) and studies of the incidence of avian influenza among domestic birds, are classed in 636.50894518 Incidence of and public measures to prevent influenza in domestic poultry (built with 614.518 Incidence of and public measures to prevent influenza). Works about pathology, diagnosis, treatment of avian influenza in domestic poultry are classed in 636.50896203 Influenza in domestic poultry (built with 616.203 Influenza). These same numbers are used for comprehensive works on all kinds of domestic birds. Works about influenza in swine are classed in similar numbers, with the base number 636.4 Swine: 636.40894518 Incidence of and public measures to prevent influenza in domestic swine and 636.40896203 Influenza in domestic swine.
Works about public health measures to prevent the spread of influenza among humans, and studies of incidence of humans infected with influenza, are classed in 614.518 Incidence of and public measures to prevent influenza.
Works about pathology, diagnosis, treatment of influenza in humans are classed in 616.203 Influenza.
