Graziers urged to vaccinate cattle as three-day sickness spreads
Veterinarians are urging graziers in north Queensland to vaccinate their cattle as an unseasonal outbreak of bovine ephemeral fever, also known as three-day sickness, spreads. The virus has caused unusual deaths in cattle over 24 to 48 hours, with significant losses reported in Hughenden and Charters Towers. The outbreak is believed to have been spread by mosquitoes, and while there is no risk to humans, the severity of symptoms has raised concerns about a potential change in the virus.
