“…Many serological surveys of occupational groups overseas have indicated that farmers have shown a proportion already positive for Q fever, 27% in English farmers [34] and 24% in sheep farmers in Sweden [35]. This outbreak supports the findings from Queensland that farmers are an important, often overlooked and harder to reach, occupational group at high risk of acquiring Q fever infection in Australia [15].…”

“…The majority of Q fever cases have been linked to occupational exposure; however, there have also been a number of cases where a source could not be identified [13]. A number of serological and epidemiological surveys undertaken in Queensland and NSW have highlighted the high prevalence of exposure in people working with livestock and living in rural communities [14][15][16][17].…”

A windy day in a sheep saleyard: an outbreak of Q fever in rural South Australia

In December 2004, the Department of Human Services investigated an outbreak of Q fever in South Australia. A case-control study tested an association between attending a local saleyard and human illness. A case was defined as a person with clinical illness and evidence of seroconversion or high phase II IgM. Controls were selected from a database of community controls matched on sex, age group and postcode. Matched analysis of the first 15 cases with 45 controls indicated that contracting Q fever was associated with attending the saleyard on one particular day (adjusted odds ratio 15·3, 95% confidence interval 1·7-undefined, P = 0·014). Saleyard conditions were windy and conducive for airborne dispersal of contaminated particles. In total, 25 cases were detected. Of these, 22 cases had attended a local saleyard on the same day. This outbreak suggests cases were probably infected by a single exposure at a saleyard from infected sheep and dust. The investigation resulted in an increase in the local uptake of Q fever vaccination and extension of the Australian national vaccination programme.

“…Despite low seroprevalence detected in this study, contact with sheep should still be considered a risk factor for Q-fever in humans and precautions should be taken to reduce the risk of zoonotic C. burnetii transmission. Sheep have been associated with cases of Q-fever in humans in Australia and overseas [10,15,32,[44][45][46][47][48]. Coxiella burnetii shedding can occur from both symptomatic and asymptomatic sheep, and in the absence of detectable seroconversion [49,50].…”

Coxiella burnetii can cause reproductive disease in sheep and zoonotic Q-fever infections in humans. The role of infectious diseases including coxiellosis in causing poorer reproductive performance of primiparous ewes is not well studied. The aim of this study was to determine if natural exposure to C. burnetii is associated with poor reproductive performance of primiparous ewes and compare seroprevalence of primiparous and multiparous ewes. Coxiella burnetii seroprevalence was 0.08% (95% confidence interval 0.01, 0.36) in primiparous ewes and 0.36% (0.07, 1.14) in mature ewes. Coxiella burnetii was not detected in tissue samples from aborted or stillborn lambs using molecular diagnostic tests (qPCR). These findings suggest that C. burnetii infection was unlikely to be an important contributor to abortion and perinatal mortalities observed for primiparous ewes, and exposure to C. burnetii was not widespread in ewes on farms located over wide geographical region of southern Australia.
