We assessed seroprevalence of phase II antibodies to <jats:italic>C. burnetii<\/jats:italic> by indirect immunofluorescence assay (IFA; screening at 1\/50 dilution) of residents of 24 local government areas (LGA) of the HNE region of NSW. A total of 2,438 randomly selected sera sent to the Hunter Area Pathology Service for routine diagnostic purposes (not Q fever testing) during the period of 2006\u20132009 were tested. The overall seroprevalence in sample group was 7%. The proportion of males (59%) was higher than females (41%). In age distribution, the largest proportion (37%) of seropositives was in the &gt; 60 years age group. Lower prevalence was observed in 0\u20139 years (1%) and 10\u201319 years (5%) age groups. The seroprevalence in different LGAs varied between 0.5% and 22%. It was highest in Guyra (22%), Gunnedah (21%), Tenterfield (18%), and Narrabri (16%), with Newcastle (0.5%), Port Stephens (2%), Lake Macquarie (3%), and Singleton (3%) being the lowest. In most of the LGAs, seroprevalence was between 6% and 12%. This report indicates a considerable exposure to <jats:italic>C. burnetii<\/jats:italic> of residents in rural areas of the HNE region and is consistent with the high notification rate for Q fever in this part of Australia.<\/jats:p>","DOI":"10.4269\/ajtmh.2011.10-0268","type":"journal-article","created":{"date-parts":[[2011,2,3]],"date-time":"2011-02-03T17:02:07Z","timestamp":1296752527000},"page":"318-320","source":"Crossref","is-referenced-by-count":21,"title":["Seroprevalence to Coxiella burnetii Among Residents of the Hunter New England Region of New South Wales, Australia"],"prefix":"10.4269","volume":"84","author":[{"given":"Aminul","family":"Islam","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Ferguson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rod","family":"Givney","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Graves","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2795","reference":[{"key":"R1","series-title":"Med J Aust","first-page":"281","article-title":"\u2018Q' fever, a new fever entity: clinical features, diagnosis and laboratory investigation","volume":"11","author":"Derrick","year":"1937"},{"key":"R2","series-title":"Vet Microbiol","first-page":"337","article-title":"A survey of Western Australian sheep, cattle and kangaroos to determine the prevalence of Coxiella burnetii","volume":"143","author":"Banazis","year":"2010"},{"key":"R3","series-title":"Aust J Exp Biol","first-page":"17","article-title":"Coxiella burnetii in kangaroos and kangaroo ticks in western Queensland","volume":"38","author":"Pope","year":"1960"},{"key":"R4","series-title":"Aust J Exp Biol Med Sci","first-page":"99","article-title":"Studies in the epidemiology of Q fever. 2.
