A cluster of leptospirosis cases associated with crocodile workers in the Northern Territory, Australia, 2022.

Leptospirosis is a worldwide zoonotic waterborne disease endemic in tropical and subtropical climates. Outbreaks have been observed in the Northern Territory (NT) of Australia. We briefly described the epidemiology of leptospirosis in the NT between 2012 and 2022, and undertook an investigation of a cluster of three leptospirosis cases observed in crocodile workers between January and December 2022 in the Top End of the NT. A descriptive case series was conducted to investigate the cluster; all three cases were male and non-Aboriginal with a median age of 46.5 years; none took chemoprophylaxis; only one of the three cases reported wearing appropriate protective attire; all reported receiving limited to no education about personal protective measures from their associated workplaces. Higher than average rainfall in both February and December 2022 likely contributed to the increased risk of infection in those months. Changing climate patterns are likely to result in more frequent periods of heavy rain, and risk of contracting leptospirosis in the NT may increase, particularly for those who work in wet and muddy conditions. Promoting the use of protective workplace clothing and equipment, the use of waterproof dressings for skin abrasions, regular hand hygiene, and the consideration of chemoprophylaxis in certain circumstances may prevent future cases.

Aboriginal women's stories of sexually transmissible infection transmission and condom use in remote central Australia.

BACKGROUND: Sexually transmissible infection (STI) rates are persistently high in central Australia, creating conditions for a potential HIV pandemic in the area. There is a shortage of qualitative research examining the underlying factors affecting STI transmission in this region. The present study investigates Aboriginal women's current levels of knowledge regarding STI and their transmission, perception of risk for STI, patterns of condom use, access to condoms and experiences of condom negotiation with their partners. It also explores the sociocultural context of their sexual health. METHODS: The present study used qualitative methods with a semistructured questionnaire. Twenty-four women aged 18-35 years from one remote central-Australian Aboriginal community were recruited. RESULTS: The results revealed poor understandings of STI transmission, limited access to condoms and low levels of condom use despite a high perception of risk to STI. They also identified specific issues facing these women regarding the sociocultural context of their condom use, their access to condoms and the transmission of STI. The perceived effects of alcohol abuse, infidelity, sexual assault and shame on the acquisition of STI were significant issues for the women. CONCLUSION: This research has identified an urgent need for further qualitative research into the sociocultural factors that facilitate the spread of STI among Aboriginal people of remote central Australia. Implications include the need to increase their knowledge regarding STI and STI transmission, to increase women's access to condoms and to incorporate the teaching of skills to deal with sexual assault and violence into sexual-health education.
