No association between 2008-09 influenza vaccine and influenza A(H1N1)pdm09 virus infection, Manitoba, Canada, 2009.

We conducted a population-based study in Manitoba, Canada, to investigate whether use of inactivated trivalent influenza vaccine (TIV) during the 2008-09 influenza season was associated with subsequent infection with influenza A(H1N1)pdm09 virus during the first wave of the 2009 pandemic. Data were obtained from a provincewide population-based immunization registry and laboratory-based influenza surveillance system. The test-negative case-control study included 831 case-patients with confirmed influenza A(H1N1)pdm09 virus infection and 2,479 controls, participants with test results negative for influenza A and B viruses.

Mumps in prison: description of an outbreak in Manitoba, Canada.

Objective: There is a lack of published information on the management of mumps in a prison setting. We describe an outbreak of mumps that occurred in a medium-security correctional centre (Milner Ridge) in Manitoba, Canada.

Methods: A case definition of mumps consistent with that in the document "Guidelines for the Prevention and Control of Mumps Outbreaks in Canada" was adopted.

Effectiveness of the pandemic H1N1 influenza vaccines against laboratory-confirmed H1N1 infections: population-based case-control study.

Background: Excellent immune responses following 1 or 2 doses of the monovalent inactivated pandemic H1N1 vaccines have been documented, but the effectiveness of these vaccines against laboratory-confirmed H1N1 infections in the general population is not clear. We evaluated the effectiveness of the pandemic H1N1 and seasonal trivalent influenza vaccines (TIV) used during the 2009 mass vaccination campaign in Manitoba (Canada) in preventing laboratory-confirmed H1N1 infections.

Methods: A population-based case-control study using data from Cadham Provincial Laboratory (CPL) and the Manitoba Immunization Monitoring System (MIMS).

The diabetic foot clinic: not a significant source for acquisition of methicillin-resistant Staphylococcus aureus.

Background: Diabetic foot clinics have been reported as a source of acquisition of methicillin-resistant Staphylococcus aureus (MRSA). We undertook a 10-year review of patients infected or colonized with MRSA from a tertiary care hospital diabetic foot clinic and describe the epidemiology and genotypes of newly acquired MRSA in comparison with the community at large.

Methods: All new MRSA cases from the diabetic foot clinic, the hospital, and the province were reviewed to identify and compare the 10-year trend in MRSA incidence.
