BACKGROUND A storm-related disaster in New South Wales, Australia in June 2007 caused infrastructure damage, interrupted essential services, and presented major public health risks. We investigated household disaster preparedness and information sources used before and during the disaster. METHODS Rapid cluster survey of 320 randomly selected households(More)
Encephalitis is a clinical syndrome commonly caused by emerging pathogens, which are not under surveillance in Australia. We reviewed rates of hospitalization for patients with encephalitis in Australia's most populous state, New South Wales, from January 1990 through December 2007. Encephalitis was the primary discharge diagnosis for 5,926 hospital(More)
We compared the accuracy of online data obtained from the Flutracking surveillance system during pandemic (H1N1) 2009 in Australia with data from other influenza surveillance systems. Flutracking accurately identified peak influenza activity timing and community influenza-like illness activity and was significantly less biased by treatment-seeking behavior(More)
Health agencies are increasingly conducting systematic reviews of foodborne disease outbreak investigations to develop strategies to prevent future outbreaks. We surveyed state and territory health departments to summarise the epidemiology of foodborne disease outbreaks in Australia from 1995 to 2000. From 1995 through 2000, 293 outbreaks were identified,(More)
Campylobacter outbreaks are rarely detected despite Campylobacter being the most common food-borne illness notified to public health authorities. We report a prolonged outbreak of Campylobacter occurring over a three month period at a training facility. Seventy-eight cases were detected, 16 of which were confirmed Campylobacter infections. In seven affected(More)
In 2000, Australia improved national surveillance of gastro-intestinal and foodborne illness by adapting the Centers for Disease Control and Prevention's (CDC's) FoodNet model of active surveillance. The OzFoodNet surveillance network applied concentrated effort at the national and local levels to investigate and understand foodborne disease, to describe(More)
INTRODUCTION On May 26, 2009, the first confirmed case of Pandemic (H1N1) 2009 virus (pH1N1) infection in Hunter New England (HNE), New South Wales (NSW), Australia (population 866,000) was identified. We used local surveillance data to estimate pH1N1-associated disease burden during the first wave of pH1N1 circulation in HNE. METHODS Surveillance was(More)
Campylobacter is a common cause of bacterial gastroenteritis in Australia. Antibiotic resistance among Campylobacter is an emerging problem in Europe and the United States of America. Monitoring may detect emerging resistance. Since there is no epidemiologically validated subtyping system for Campylobacter, antimicrobial resistance patterns may prove useful(More)
Listeriosis is a foodborne disease associated with significant mortality. This study attempts to identify risk factors for sporadic listeriosis in Australia. Information on underlying illnesses was obtained from cases' treating doctors and other risk factors were elicited from the patient or a surrogate. We attempted to recruit two controls per case matched(More)
BACKGROUND To determine patterns of childhood lead exposure in a community living near a lead and zinc smelter in North Lake Macquarie, Australia between 1991 and 2002. METHODS An analysis of serial blood lead levels (BLL) of children less than 13 years of age in North Lake Macquarie participating in voluntary blood lead screening. Distance to the smelter(More)
