Southern Queensland general practitioners' knowledge and attitudes towards Q fever and behaviours in the management of the disease.

BACKGROUND AND OBJECTIVES: Q fever (QF) is a zoonotic disease caused by Coxiella burnetii, often associated with abattoir workers and farmers. Recent analysis suggests that QF might occur more frequently in urban areas. This study ascertains the knowledge of, and attitudes towards, QF and behaviours in the management of QF among general practitioners (GPs) across rural and urban areas. METHOD: This cross-sectional survey study targeted GPs working in regional Queensland. GPs were asked to complete a 59-item questionnaire. Logistic regression was used to compare respondent demographics with attitude ratings and knowledge scores. RESULTS: Diagnosing a patient with QF was significantly related to practitioner age, years in practice and practising in a rural area. DISCUSSION: This study shows gaps in GP QF knowledge, particularly around QF management. With increased urbanisation of rural areas potentially leading to increases in acute QF cases, GPs need to improve their knowledge of this disease.

Seroprevalence of Q fever among metropolitan and non-metropolitan blood donors in New South Wales and Queensland, 2014-2015.

OBJECTIVES: To estimate the prevalence of exposure to the causative agent of Q fever (Coxiella burnetii) and of current infections among blood donors in Australia. DESIGN, SETTING: Cross-sectional study in metropolitan Sydney and Brisbane, and in non-metropolitan regions with high Q fever notification rates (Hunter New England in New South Wales; Toowoomba in Queensland). PARTICIPANTS: Blood donors attending Red Cross collection centres during October 2014 - June 2015 who provided sera and completed a questionnaire on Q fever vaccination status, diagnosis and knowledge, and exposure history. MAIN OUTCOME MEASURES: Age- and sex-standardised seroprevalence of phase II IgG antibodies to C. burnetii (indicating past exposure) and independent risk factors for seropositivity; presence of C. burnetii DNA (indicating current infection and risk of transmission by blood transfusion). RESULTS: 2740 donors (94.5% response rate) completed the questionnaire and supplied sera for analysis. Crude antibody seroprevalence was 3.6%. Standardised seroprevalence was higher in non-metropolitan than metropolitan regions (NSW, 3.7% v 2.8%; Queensland, 4.9% v 1.6%; statistically significant only in Queensland). Independent predictors of antibody seropositivity were regular contact with sheep, cattle, or goats (adjusted odds ratio [aOR], 5.3; 95% CI, 2.1-14), abattoir work (aOR, 2.2; 95% CI, 1.2-3.9), and assisting at an animal birth (aOR, 2.1; 95% CI, 1.2-3.6). Having lived in a rural area but having only rare or no contact with sheep, cattle or goats was itself a significant risk factor (v never lived rurally: aOR, 2.5; 95% CI, 1.1-5.9). 40% of people in groups recommended for vaccination were aware of the vaccine; 10% of people in these groups had been vaccinated. C. burnetii DNA was not detected in 1681 non-metropolitan samples, suggesting that transmission by blood donation is unlikely. CONCLUSIONS: Given their exposure to multiple risk factors, vaccination against Q fever should be considered for all rural residents.

Q fever: A rural disease with potential urban consequences

BACKGROUND: Q fever often presents as an undifferentiated febrile illness. Cases occur throughout Australia, with higher rates occurring in northern New South Wales and southern Queensland. OBJECTIVE: This article aims to provide clinicians with an overview of Q fever, and covers epidemiology, clinical features, laboratory diagnosis, sequelae, management and prevention. DISCUSSION: In Australia, Q fever is the most commonly reported zoonotic disease. Presentation includes fever, rigors, chills, headache, extreme fatigue, drenching sweats, weight loss, arthralgia and myalgia, often in conjunction with abnormal liver function tests. These features make it indistinguishable from many other febrile illnesses. Exposure occurs through contact with livestock and other animals. Coxiella bacteria can survive in dust, where infection may result from inhalation. Laboratory diagnosis is made by serology or polymerase chain reaction. An effective vaccine is available for adults (aged >15 years), but can only be administered after a rigorous pre-vaccination assessment to exclude prior exposure to Coxiella burnetii, requiring a detailed medical history, skin test and serology.

Pigs, pooches and pasteurisation: The changing face of brucellosis in Australia

BACKGROUND: Brucellosis, also known as undulant, Mediterranean or Malta fever, is a systemic infection that causes fever, sweats, arthralgias and myalgias. A globally important disease, brucellosis is re-emerging in Australia in association with feral pig hunting activities. OBJECTIVE: This article aims to provide clinicians with an overview of brucellosis, covering epidemiology, clinical features, diagnosis, management and prevention. DISCUSSION: Brucellosis should be suspected in all patients with non-specific, flu-like illness who fall into one of the major risk groups (feral pig hunters, overseas travellers and migrants). Depression is common and often severe, relative to other symptoms. Early diagnosis and treatment are important for preventing complications, which include osteoarticular, genitourinary or, more rarely, neurological or cardiovascular diseases. Diagnosing acute infections is based on serology and blood cultures; imaging and biopsy may be required for diagnosis of focal infections. Dual therapy with doxycycline and gentamicin is the recommended treatment. Relapse occurs in up to 10% of patients. Prevention is achieved through the use of protective gear during hunting and avoidance of unpasteurised dairy products in countries where occur in animals.

Australian bat lyssavirus: implications for public health.

Australian bat lyssavirus (ABLV) infection in humans is rare but fatal, with no proven effective therapy. ABLV infection can be prevented by administration of a post-exposure prophylaxis regimen of human rabies immunoglobulin and rabies vaccine. All Australian bats (flying foxes and microbats) should be considered to be carrying ABLV unless proven otherwise. Any bat-related injury (bite, scratch or mucosal exposure to bat saliva or neural tissue) should be notified immediately to the relevant public health unit - no matter how small the injury or how long ago it occurred. Human-to-human transmission of ABLV has not been reported but is theoretically possible. Standard infection control precautions should be employed when managing patients with suspected or confirmed ABLV infection.
