Everything you need to know about deadly H5 bird flu

Bird flu, specifically the H5 strain, is a highly infectious virus that can affect birds, other animals, and occasionally humans. The H5 strain has never been detected in Australia before. Globally, H5 has caused severe disease and high mortality in poultry, wild birds, and affected mammals. It spreads rapidly through wild birds and via bodily fluids, droppings, and feathers. Contaminated clothing, shoes, or items such as egg cartons can also facilitate spread. Other strains such as H7 have caused serious poultry outbreaks in Australia previously but were eradicated. The Department of Agriculture, Fisheries and Forestry has urged anyone spotting sick or dead birds or other animals to record the location and report it to a 24-hour emergency hotline. Common signs in mammals include weakness, trouble breathing, tremors, seizures, or walking in circles. Wild birds may have trouble walking or breathing, while domesticated poultry may become lethargic and reluctant to eat or drink. People infected with bird flu may present fever, cough, runny nose, conjunctivitis, and fatigue, though there is no evidence of person-to-person spread for H5. Other global outbreaks have involved mammals such as dolphins, seals, and polar bears. Different avian influenza strains require surveillance and rapid reporting to prevent spread. Authorities advise reporting sick or dead birds and staying informed through reliable sources. For those in agriculture or wild-bird habitats, heightened hygiene and biosecurity are key. Readers are urged to stay updated via local outlets for the latest information.
