Interesting information on H5N1
(H5N1) can kill a wide range of birds and sicken or kill over 100 mammal species globally, including cats, dogs, cattle, goats, pigs, and seals. In Australia, high-risk native wildlife like black swans, Tasmanian devils, and sea lions are heavily monitored, though reptiles and frogs are not affected. [1, 2, 3, 4]
Birds (Primary Targets)
Waterbirds and Seabirds: Ducks, swans, geese, terns, gulls, and migratory shorebirds are natural carriers and highly vulnerable. Local transmission has caused mass deaths in Australian greater crested terns.
Scavengers and Raptors: Birds of prey (like eagles, hawks, and falcons) and gulls die after eating infected carcasses.
Land Poultry: Chickens, turkeys, and ducks on commercial or backyard farms face severe mortality if exposed. [1, 2, 3, 4, 5]
Domestic Pets and Livestock
Cats: Highly susceptible; infection usually comes from eating sick wild birds or raw meat, causing severe neurological signs, blindness, and high fatality rates. [1, 2, 3]
Dogs: Low susceptibility, but can be infected overseas through scavenging dead animals. [1, 2]
Cattle (Dairy): Proven internationally to catch the virus (exhibiting drops in milk production and respiratory signs), though not yet detected in Australian livestock. [1, 2]
Goats, Sheep, and Pigs: Affected sporadically overseas via contaminated environments or infected birds. []
Native Australian Wildlife
Marine Mammals: Australian sea lions, fur seals, and dolphins are at extreme risk based on catastrophic seal mortalities recorded globally and on sub-antarctic Australian territories.
Carnivorous Marsupials: Species like the endangered Tasmanian devil and quolls face high vulnerability threat rankings due to scavenging behavior.
Platypus: While aquatic mammals can be exposed, direct high vulnerability for monotremes like the platypus remains less common, though all unique native fauna lack historic immunity
Scavenging Infected Carcasses: Because Australia lacks vultures, native dingoes and invasive European red foxes act as the primary carcass "clean-up crew". [1, 2]
Impact: Globally, foxes have suffered frequent, severe neurological deaths from H5N1. In Australia, federal risk assessments project that dingoes could face moderate population declines as the virus spreads. [1, 2]
High Viral Loads: Eating wild birds that have died from the virus exposes these animals to incredibly high, lethal concentrations of H5N1. [1, 2]
Exempt: Reptiles, fish, and amphibians (frogs) are not known to be affected by the virus.
