Am J Infect Control 2012 40 (8) 726-31 BACKGROUND: Hepatitis B virus (HBV) transmission has been reported after patient-to-patient blood exposure during assisted monitoring of blood glucose (AMBG). Three assisted-living facility (ALF) residents who underwent AMBG developed acute HBV infection (HBVI) within 10 days. We investigated HBV transmission and implemented preventive measures. METHODS: A retrospective cohort study was conducted. Infection control practices were assessed. HBVI screening was conducted for all staff and epidemiologically linked residents. Viral DNA sequences were compared for a subset of isolates. RESULTS: Lancing devices and glucometers were shared among residents without proper sanitization. Serologic testing of all 34 residents with diabetes and 12 epidemiologically linked residents present during the exposure period detected 6 residents with diabetes with current HBVI and 4 residents with diabetes and 1 epidemiologically linked resident with previous HBVI. A cohort study of 32 individuals with diabetes identified AMBG as a significant risk factor for HBVI (relative risk, 6.7; 95% confidence interval, 1.7-26.3). Viral DNA sequences for 5 AMBG-exposed residents' isolates were identical, suggesting a common source. CONCLUSIONS: AMBG was significantly associated with HBVI in ALF residents with diabetes. Despite clear preventive recommendations, bloodborne pathogen transmission continues to occur in the setting of AMBG. Strengthening direct care provider, infection preventionist, and health department partnerships with ALFs is crucial to ensure safe AMBG practices and prevent HBV transmission. |
Public health approach to detection of non-O157 Shiga toxin-producing Escherichia coli: summary of two outbreaks and laboratory procedures

Epidemiol Infect 2011 140 (2) 1-7 SUMMARY: Routine laboratory testing may not detect non-O157 Shiga toxin-producing Escherichia coli (STEC) reliably. Active clinical, epidemiological, environmental health, and laboratory collaboration probably influence successful detection and study of non-O157 STEC infection. We summarized two outbreak investigations in which such coordinated efforts identified non-O157 STEC disease and led to effective control measures. Outbreak 1 involved illness associated with consuming unpasteurized apple cider from a local orchard. Public health personnel were notified by a local hospital; stool specimens from ill persons contained O111 STEC. Outbreak 2 involved bloody diarrhoea at a correctional facility. Public health personnel were notified by the facility infection control officer; O45 STEC was the implicated agent. These reports highlight the ability of non-O157 STEC to cause outbreaks and demonstrate that a coordinated effort by clinicians, infection-control practitioners, clinical diagnostic laboratorians, and public health personnel can lead to effective identification, investigation, and prevention of non-O157 STEC disease. |
