Abstract. Q fever is a worldwide zoonosis historically associated with exposure to infected livestock. This study summarizes cases of Q fever, a notifiable disease in the United States, reported to the Centers for Disease Control and Prevention through two national surveillance systems with onset during 2000-2012. The overall incidence rate during this time was 0.38 cases per million persons per year. The reported case fatality rate was 2.0%, and the reported hospitalization rate was 62%. Most cases (61%) did not report exposure to cattle, goats, or sheep, suggesting that clinicians should consider Q fever even in the absence of livestock exposure. The prevalence of drinking raw milk among reported cases of Q fever (8.4%) was more than twice the national prevalence for the practice. Passive surveillance systems for Q fever are likely impacted by underreporting and underdiagnosis because of the nonspecific presentation of Q fever.

“…Domestic ruminants (cattle, sheep, and goats) are described as the primary reservoir species for exposure of humans [1,[17][18][19]. In dairy cattle C. burnetii infections may be underrecognized [19,20] and there is incomplete understanding of infection dynamics and disease manifestations. In the United States there are currently no approved C. burnetii are inconsistent [8,15,24].…”

-The objective of this research was to explore the potential association between Coxiella burnetii shedding in milk and chronic subclinical mastitis in dairy cattle. In two separate studies, we identified an association between PCR-based detection of C. burnetii in milk and chronic subclinical mastitis in lactating dairy cows. These studies were conducted in a commercial dairy herd where there was ongoing intensive monitoring of subclinical mastitis by aerobic bacteriology, but no prior knowledge or management of C. burnetii infections. In a case-control study, quarter level C. burnetii status determined by real-time quantitative PCR (RT-qPCR) was strongly associated with chronic subclinical mastitis as measured by milk somatic cell counts. In a subsequent cross sectional study, 147 (45%) of 325 lactating cows were positive for C. burnetii by RT-qPCR of composite milk samples. In a generalized linear model, accounting for the effect of covariates including aerobic intramammary infection status, C. burnetii PCR status was a significant predictor of linear somatic cell count score. In agreement with a small number of previous reports, this research provides evidence that there may be mammary gland specific manifestations of C. burnetii infections in dairy cattle.

“…Because Q fever is not a notifiable disease in Canada, the actual number of Q fever cases diagnosed annually is unknown. In the United States of America, Q fever became nationally reportable in 1999 with 255 Q fever cases reported from 2000-2004. It is presumed that many more cases of Q fever occur annually but likely go unreported because of the nonspecific nature of the clinical symptoms and lack of definitive early diagnostic tests (McQuiston et al 2006).…”
