Practical guidance for clinical laboratories for SARS-CoV-2 serology testing
Can Commun Dis Rep. 2021 May 7;47(4):171-183. doi: 10.14745/ccdr.v47i04a01. eCollection 2021 May 7.ABSTRACTThe landscape of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diagnostic testing is rapidly evolving. While serology testing has limited diagnostic capacity for acute infection, its role in providing population-based information on positivity rates and informing evidence-based decision making for public health recommendations is increasing. With the global availability of vaccines, there is increasing pressure on clinical laboratories to provide antibody screening and result interpretation for vaccinat...

Can Commun Dis Rep. 2021 May 7;47(4):209-215. doi: 10.14745/ccdr.v47i04a05. eCollection 2021 May 7.ABSTRACTBACKGROUND: The Canadian Paediatric Society no longer recommends the use of universal ocular prophylaxis with erythromycin ointment to prevent ophthalmia neonatorum. Screening for Chlamydia trachomatis and Neisseria gonorrhoeae in all pregnant women is considered the most effective way of preventing vertical transmission and ophthalmia neonatorum.OBJECTIVE: The aims of this study were to assess prenatal screening rates of C. trachomatis and N. gonorrhoeae and to compare sociodemographic factors between those screened ...

COVID-19 outbreak in a personal service setting in Kingston, Ontario, 2020
CONCLUSION: The interplay of aggressive accessible testing, quick lab turnaround time, contact tracing within 24 hours of positive laboratory results as per provincial standards, frequent public communication, rapid inspections, mandatory self-isolation and face coverings were measures successful in halting the outbreak. Inspections or self-audits should be required at all PSSs prior to reopening and outbreak management must work with PSSs to reduce the possibility of superspreading events.PMID:34035668 | PMC:PMC8127683 | DOI:10.14745/ccdr.v47i04a06 (Source: Can Commun Dis Rep)

This article, the second in a series on the six National Collaborating Centres for Public Health, focuses on the National Collaborating Centre for Healthy Public Policy (NCCHPP), a centre of expertise, and knowledge synthesis and sharing that supports public health actors in Canada in their efforts to develop and promote healthy public policy. The article briefly describes the NCCHPP's mandate and programming, noting some of the resources that are particularly relevant in the current coronavirus disease 2019 (COVID-19) context. It then discusses how the NCCHPP's programming has been adapted to meet the changing needs of pu...

COVID-19 outbreak in a personal service setting in Kingston, Ontario, 2020
CONCLUSION: The interplay of aggressive accessible testing, quick lab turnaround time, contact tracing within 24 hours of positive laboratory results as per provincial standards, frequent public communication, rapid inspections, mandatory self-isolation and face coverings were measures successful in halting the outbreak. Inspections or self-audits should be required at all PSSs prior to reopening and outbreak management must work with PSSs to reduce the possibility of superspreading events.PMID:34035668 | PMC:PMC8127683 | DOI:10.14745/ccdr.v47i04a06 (Source: Can Commun Dis Rep)

Ethics check-up of public health immunization programs in Canada
Can Commun Dis Rep. 2021 May 7;47(4):224-231. doi: 10.14745/ccdr.v47i04a09. eCollection 2021 May 7.ABSTRACTThe World Health Organization (WHO) recognizes immunization as one of the most successful and effective public health interventions for saving lives. In developing a roadmap for prioritizing use of the coronavirus disease 2019 (COVID-19) vaccines in the context of limited supply, WHO highlighted the importance of a values (ethical principles) framework. Immunization does need to be subject to independent ethical scrutiny of vaccine research data, manufacturing practices, the legal and ethical assurance of informed con...

The National Collaborating Centre for Healthy Public Policy in times of COVID-19: Building skills to "Build Back Better"
This article, the second in a series on the six National Collaborating Centres for Public Health, focuses on the National Collaborating Centre for Healthy Public Policy (NCCHPP), a centre of expertise, and knowledge synthesis and sharing that supports public health actors in Canada in their efforts to develop and promote healthy public policy. The article briefly describes the NCCHPP's mandate and programming, noting some of the resources that are particularly relevant in the current coronavirus disease 2019 (COVID-19) context. It then discusses how the NCCHPP's programming has been adapted to meet the changing needs of pu...

Practical guidance for clinical laboratories for SARS-CoV-2 serology testing
Can Commun Dis Rep. 2021 May 7;47(4):171-183. doi: 10.14745/ccdr.v47i04a01. eCollection 2021 May 7.ABSTRACTThe landscape of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diagnostic testing is rapidly evolving. While serology testing has limited diagnostic capacity for acute infection, its role in providing population-based information on positivity rates and informing evidence-based decision making for public health recommendations is increasing. With the global availability of vaccines, there is increasing pressure on clinical laboratories to provide antibody screening and result interpretation for vaccinat...
