A pregnant woman in Australia has tested positive for the Zika virus after travelling overseas.

The Queensland state Department of Health said that the woman was diagnosed with the disease after returning from a trip abroad.

The department declined to provide additional details, such as which country the woman had visited, saying only it was not a locally acquired case of the virus.

Last week, another woman in Queensland was diagnosed with Zika after returning from a trip to El Salvador.

Experts in Australia have said the risk of Zika spreading across the nation is extremely low. The type of mosquito that carries the virus only lives in the far north-east corner of the country, which is sparsely populated.

And in China...

China also reported that its first case of the Zika virus has been found in a 34-year-old man who recently travelled to Venezuela.

The man, from the southern city of Ganzhou, was treated in Venezuela on January 28 before returning home on February 5 via Hong Kong and the southern Chinese city of Shenzhen, the National Health and Family Planning Commission said.

The commission said he was confirmed as having the virus yesterday and was being treated at the Ganxian People's Hospital. His temperature was now normal and a skin rash was receding, it added.

It said the chances of the virus spreading in China were "extremely low" due to cold winter temperatures and a lack of mosquito activity, the primary avenue by which Zika spreads.

The Zika virus is spreading rapidly through Latin America. Most people who contract it have either mild or no symptoms, but it is suspected of causing a birth defect that results in babies born with abnormally small heads.
