Environmental Health Resources for the COVID-19 Pandemic

Printer Friendly, PDF & Email

The transmission of SARS-CoV-2, the virus that causes COVID-19, occurs primarily via direct contact with or respiratory droplets from an infected person. However, there is evidence to suggest that transmission via other modes – such as contaminated surfaces, aerosols, or contact with fecal material – is possible. As such, environmental health practitioners have a key role to play in promoting general hygiene measures as well as addressing unique information needs as the pandemic affects all aspect of public and private life.

This topic page has been created to promote key COVID-19 resources to environmental health practitioners and related professions. We are actively collecting and curating resources from more than 50 Canadian and international public health agencies, and will be promoting those resources via social media and by providing the essential resources on this topic page. This information is current to the date at the bottom of the page.
