More and more heterosexual men visiting Papua New Guinea and Southeast Asian countries are turning with HIV infection, Australian authorities have revealed.
The trend has been detected among miners and other workers based in Queensland, the Northern Territory and Western Australia, and has some experts concerned it could provide the virus with a route into the mainstream population.
As new national figures show numbers of new HIV infections overall continuing to increase nationally, doctors attending a Perth conference yesterday told reporters that six Queensland businessmen had been diagnosed with HIV in the past year after liaisons with women in Papua New Guinea.
Cairns Sexual Health service director Darren Russell said unlike in previous cases, all the men are believed to be heterosexual. The infected are in the 47-66 age group.
Dr Russell says three of the businessmen have female partners in Cairns but none of the women have contracted the disease.
"We're fairly confident that with these men there hasn't been any ongoing transmission of the HIV to other women in Cairns," he said.
"What we are concerned about though is that there might be other men out there who haven't been tested for HIV and aren't aware they have HIV."
"The other concern of course is our border region in the Torres Strait, which is very close to Papua New Guinea and so far there don't seem to be any transmissions across that border, but we're concerned that it's only a matter of time," he said.
