The Delta variant is putting young, healthy people at risk of fatal cardiac complications. Professor Jason Kovacic, from the Victor Chang Cardiac Research Institute, explained that the Delta variant appears to be causing more serious infections and complications in young people. Myocarditis (inflammation of the heart), and blood clots are some of the most concerning side effects seen with Delta. Prof Kovacic predicts, “It may be inevitable that more young people die as this outbreak is set to get worse, but hopefully it’s a very, very, very low number.”
