50 swans killed by mystery virus in Cork

A mystery virus has killed around 50 swans in The Lough area of Cork city over the past few days.

Cork City Council has yet to say how long it has been aware of the problem, but it has been removing the dead swans for the past few days.

The virus is understood to have been introduced by migratory ducks that have settled in the area.

Officials say the illness only affects fowl species and poses no threat to humans.
