Queensland has now confirmed two cases of Zika virus, as officials in some infected countries are advising women to delay becoming pregnant and Australian authorities urge pregnant women to defer travel to affected areas.

A child who recently returned to Brisbane from Samoa with family after a holiday is the second confirmed case of the virus in 24 hours.

Queensland Chief Health Officer Dr Jeanette Young said the child had presented to a Brisbane hospital and the result had come through on Saturday morning.

A woman is recovering from Zika on the Gold Coast after returning from El Salvador in Central America where the mosquito-borne virus is spreading quickly.
