Researchers at the Florey Institute of Neuroscience and Mental Health in Melbourne infected male mice with the virus and mated them with healthy females.
The research published in Nature Communications found all offspring from infected fathers exhibited these behavioural changes.
Co-senior author Carolina Gubert explained this may contribute to increased anxiety via epigenetic inheritance and altered brain development.
Researchers discovered the virus altered RNA molecules in the fathers’ sperm, affecting genes important for brain development.
