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…

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.

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…

This presentation synthesizes available evidence on environmental health risks associated with the physical environment in encampments, and best practices to prevent the transmission of SARS-CoV-2, to serve as guidance for environmental health practice as an integral part of a multi-sectoral approach to ensure people stay safe and healthy during their time in an encampment.

This presentation reviewed current understanding of the key risks associated with the performing arts sector, and the precautions for minimizing risks of COVID-19 transmission in various settings. It will be of interest to environmental and public health professionals developing guidance and recommendations for safe resumption of performing arts activities as well as those working in the sector.

Related Evidence Review: COVID-19 Risks and precautions for the performing arts

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…

Fomite transmission is acknowledged as one of the potential transmission routes of SARS-CoV-2. Thus, appropriate cleaning and disinfection of surfaces is one of the non-pharmaceutical control measures recommended by public health. However, while adequate cleaning and disinfection may be important to sever this chain of transmission of COVID-19, excessive cleaning and disinfection has led to an increase in accidental exposure to harmful cleaning and disinfection by-products due to heightened concerns about SARS-CoV-2 persisting on food, food packaging, and environmental surfaces. Improving public health practitioners’ understanding of appropriate cleaning and disinfection practices and the risks of misuse and overuse of disinfectant products would help to guide public health recommendations in public and private settings.

Building on the success of the Healthy Built Environment Toolkit, BCCDC is developing a complimentary framework which focuses on supporting social connections and resiliency. This resource will offer evidence based practice principles for local governments and other stakeholders looking for guidance on how to “build back better”, minimize unintended consequences, and work towards more equitable and sustainable communities. We are now in the final stages of synthesizing over 2000 research associations and expert feedback and are aiming to complete the final full report in Feb 2021. This webinar will review version 1 of the framework and share some examples of how it may be used to support practice. This resource is developed in consultation with a diverse Advisory Group, content experts across BC, and representatives from Alberta and Manitoba.
