Webinar Recording: COVID-19 management in personal services settings: Lessons learned from a nail salon outbreak

Topics: COVID-19

Between June 20 and July 3, 2020 a COVID-19 outbreak associated with a personal service setting (PSS) was detected in the Kingston, Ontario and managed by the local public health unit (KFL&APH).

A mixed-methods analysis was conducted to review KFL&APH’s response to the outbreak. A social network analysis was conducted to determine the extent of the outbreak and route of acquisition of cases. Epidemic curves were created and analysed. Attack rates were calculated, and testing data and overall testing strategy were reviewed.

The outbreak consisted of 37 cases with 14 through direct PSS exposure. 23 cases were from subsequent generations, and a superspreading event led to 14 of those cases. The average age of cases was 38.6 years and 65% were female. One case required hospitalization. Over 10 000 tests were conducted using a multimodal approach, including fixed assessment centres, drive-through testing and targeted testing at outbreak sites. PCR lab results…

Conducting a Literature Search and Semi-Systematic Review: The NCCEH Approach

Evidence-informed decision-making seeks to incorporate both scientific or academic knowledge, as well as the practical knowledge of public health professionals. However, the use of scientific evidence is hindered by a number of factors, particularly the lack of an easy-to-use protocol to search, appraise and synthesize academic sources in a timely manner. In this document, we provide an overview of semi-systematic literature reviews as a way to incorporate scientific evidence into EIDM, and we provide a step-by-step protocol encompassing literature search, critical appraisal, and synthesizing new knowledge. The intent of this document is to both assist public health practitioners who wish to conduct their own reviews, as well as provide insight in to the literature review process at NCCEH.

Webinar Recording: COVID-19 Precautions for Multi-unit Residential Buildings

Topics: COVID-19

The NCCEH Environmental Health Seminar Series provides an opportunity for learning and knowledge exchange on a variety of environmental health topics. The seminars can be attended in-person or online.

Presenter: Dr. Angela Eykelbosh, Environmental Health & Knowledge Translation Scientist, NCCEH The transmission of COVID-19, which occurs primarily through close contact with an infected person, has made it necessary for large proportions of the world’s population to self-isolate in their homes. However, those dwelling in multi-unit residential buildings (MURBs) face additional challenges as they must necessarily use and share common areas and facilities, and are dependent upon building managers to maintain good indoor environmental quality (IEQ). Based on a recent NCCEH publication, this webinar will look at some of the evidence on COVID-19 transmission and consider how this applies to transmission risk in MURBs. We will discuss current cleaning and sanitation guidance…

Indoor environmental quality of sustainable building designs and occupant health

The NCCEH Environmental Health Seminar Series provides an opportunity for learning and knowledge exchange on a variety of environmental health topics. The seminars can be attended in-person or online.

Presenter: Dr. Karen Bartlett, School of Population and Public Health, University of British Columbia

Occupants of buildings depend on what we term “good” Indoor Environmental Quality (IEQ). The actual definition of IEQ is somewhat elusive, as it is the absence of problems in the indoor environment which could detract from the health and productivity of occupants. Buildings need to be designed and built with the occupant in mind, and as we rapidly progress into sustainable building designs, we also need to make sure that buildings can accommodate the changing environments of our cities and climate. We will explore some of the facets of the occupant/building interface in these changing environments.

Presenters: Lori Holmes, Huron Perth Public Health; Sunil Varughese, Public Health Ontario; Vince Spilchuk, Public Health Ontario

Cosmetics, such as skin creams containing mercury, have long been used in several countries for skin-lightening, anti-aging and acne treatment effects. The harmful effects of mercury to human health are well known. Although many countries including Canada have restricted its use in cosmetics to protect the public from mercury exposure, production and subsequent access to these products continues to occur.

The following presentation will outline a recent case of mercury poisoning in an infant that led to a collaborative public health investigation involving provincial, federal and international public health stakeholders. Through the…

Presenter: Tissa Rahim, Project Coordinator, BC Centre for Disease Control

Under legalization of cannabis in the United States poison centres reported an increase in calls about cannabis exposures compared to those in states where cannabis remained illegal during both the lead up to and just after legalization/decriminalization. In 2018 the BC Drug and Poison Information Centre (DPIC) received 644 calls as compared to 241 calls received in 2013. Many adverse effects reported were from people exposed to products that are not yet regulated, including those that were purchased from unlicensed stores/online, or from taking cannabis in combination with other substances. DPIC also received calls about children accidentally exposed to edibles, particularly candies, and…

Paradox of Wealth and Health: Resource Development and Social Determinants of Health

The BCCDC/NCCEH Environmental Health Seminar Series provides an opportunity for learning and knowledge exchange on a variety of environmental health topics. The seminars can be attended in-person or online.

Speakers: Barbara Oke, Regional Manager, Health and Resource Development, Northern HealthMelissa Aalhus, Health and Resource Development Technical Advisor, Northern Health

The understanding and management of health impacts associated with natural resource development activities like pipelines, mines and processing facilities, has traditionally focused on the impacts from biophysical exposures (e.g. changes to air quality, water quality, etc.). However, extensive research conducted over the past three decades leaves little doubt that social factors are powerful determinants of health and much evidence is emerging that the social, cultural and economic impacts of resource extraction and development are highly complex and intersect to shape health outcomes of…

Presentation 1: Exploring the Relationship between the Built Environment and Social Isolation and Loneliness: Implications for Public Policy

Summary: Purported to be as much of a risk factor for premature mortality as smoking 15 cigarettes per day, social isolation and loneliness is a significant predictor of adverse health outcomes. Through the application of a social ecological lens, a semi-systematic review was conducted to understand the association between the built environment and social isolation and loneliness. This webinar will present the findings of this research.

Unwrapped – Plastic Food Contact Articles And Chemical Food Safety

The BCCDC/NCCEH Environmental Health Seminar Series provides an opportunity for learning and knowledge exchange on a variety of environmental health topics. The seminars can be attended in-person or online.

Speaker: Shirra Freeman, Environmental Health and Knowledge Translation Scientist, NCCEH

Summary: Plastics are emerging as an important environmental public health (EPH) issue. Within this issue, the safety of plastic food contact articles (PFCA) is especially important for EPH practice. PFCA are designed to safeguard the quality and safety of food and are used extensively in food service and retail settings. Plastic packages, utensils, surfaces, equipment and components provide cost-efficient, convenient solutions for handling, processing, preparing and serving food. The main safety concern is that under certain conditions, toxic chemicals may leach from PFCA into foods, exposing consumers to health risks.
