BACKGROUND  Escherichia coli O157:H7 is a Shiga toxin-producing E. coli (STEC) associated with numerous foodborne outbreaks in the United States and is an important cause of bacterial gastrointestinal illness. In May 2009, we investigated a multistate outbreak of E. coli O157:H7 infections. METHODS  Outbreak-associated cases were identified using(More)
During the 2003-04 influenza season, 17 cases of Staphylococcus aureus community-acquired pneumonia (CAP) were reported from 9 states; 15 (88%) were associated with methicillin-resistant S. aureus (MRSA). The median age of patients was 21 years; 5 (29%) had underlying diseases, and 4 (24%) had risk factors for MRSA. Twelve (71%) had laboratory evidence of(More)
Because of the difficulty of identifying infected persons, current recommendations for infection control are to treat all patients as if they are infected with blood-borne pathogens such as human immunodeficiency virus (HIV) and the hepatitis viruses. Dentists' compliance with these recommendations has been investigated previously, however, there are few(More)
OBJECTIVES The objective of this study was to investigate compliance with recommended infection control (IC) practices by dentists in Canada in 1995. DESIGN A mailed survey of a stratified random sample of dentists (N = 6444), with 3 follow-up attempts. Weighted analyses included multiple logistic regression to identify the best predictors of "excellent"(More)
OBJECTIVE This study investigated late response and nonresponse bias in an HIV-related survey of dentists. METHODS Questionnaires with ID numbers were mailed to all dentists in Ontario (N = 5,997) with additional mailings four and seven weeks later. RESULTS Proportionately more respondents who returned questionnaires less than four weeks after the first(More)
State-funded healthcare systems increasingly recognize accountability as an important public policy issue. This article explores significant aspects of current theory and practice in order to describe an accountability framework for the Canadian health system. Stakeholders include governments, institutions, providers and patients. Their relationships may be(More)
OBJECTIVES To measure the frequency of occupational exposures reported by dentists in Canada and to identify factors associated with occupational exposure. DESIGN A national mailed survey of a stratified random sample of 6,444 dentists with three follow-up attempts. Weighted data were analyzed using t tests, analysis of variance, and multiple logistic(More)
We compared human and bovine isolates of Salmonella enterica using antimicrobial-drug resistance profiles and pulsed-field gel electrophoresis. From 2000 through 2006, we observed an increase in a novel multidrug-resistant clone of S. Typhimurium with no recognized phage type. This clone may represent an emerging epidemic strain in the Pacific Northwest.
OBJECTIVES To investigate age- and population-based differences in dentists' infection control practices and willingness and refusal to treat patients with HIV. METHODS A national mailed survey of a stratified random sample of dentists in Canada (n = 6444) with three follow-up attempts. Pearson's chi-square test and multiple logistic regression were used(More)
OBJECTIVES Although much of the economic impact of child care-associated illness in the United States is due to parents' time lost from work, there are no data on the incidence of absence due to illness among children in various types of out-of-home child care settings in the United States. The goals of this study were to compare the incidence of illness(More)
