Queensland woman diagnosed with Zika following trip to Tonga

Residents of Bowen in north Queensland, Australia have been urged to kill mosquitoes in and around their homes following a confirmed imported case of Zika virus.

The Mackay Hospital and Health Service (MHHS) said a woman tested positive to the virus on Friday after returning from Tonga earlier this month.

ABC reports she has since been admitted to Townsville Hospital and is said to be doing well.

The Public Health Unit is working with Whitsunday Regional Council to coordinate further home visits, helping to remove breeding sites and spraying inside.

Zika is a mosquito-borne illness closely related to dengue.

The illness is usually milder, but complications may include birth defects in pregnant women.

There have been about a dozen cases in Queensland so far this year.

North Queensland Public Health physician Dr Steven Donohue said residents in the area have been asked to spray their homes.

"On Saturday, and again today and tomorrow, mosquito control teams helped by Queensland Health and Whitsunday Council have been going house to house in parts of Bowen," Dr Donohue said.

"But I think really what everybody in Bowen needs to do now is spray their house and kill mosquitoes."

MHHS said it was best to spray in and around the property in dark hiding places with an ordinary surface or cockroach insect spray, and to tip out or remove anything holding water in the yard.

MHHS said the risk of transmission was low as the infected resident was only home for a few days while unwell.

Zika cannot be transmitted from person to person.
