The University of Queensland has found that Australian travelers are spreading drug-resistant gonorrhea at an increasing rate, with half spending time in certain global hotspots. The study also found that backpackers are more likely to contract chlamydia, people visiting family or friends, and men who had sex with men contract gonorrhoea and HIV more often than the general public. The researchers have called for sexual health advice to be included in general medical advice given to Australian travelers. They also suggested that only 22.4 percent of Australian clinicians offered pre-travel sexual health advisories. The rise in infections transmitted through sexual contact has become a significant public health challenge, particularly with the rise in international travel.
