As the SARS-CoV-2 virus drives a worldwide pandemic, our scientific understanding of how it is transmitted is constantly evolving. There is an ongoing debate on various aspects of this process, particularly aerosol transmission.

In the implementation of Québec’s 2013-2020 Climate Change Action Plan, the ministère de la Santé et des Services sociaux mandated the Institut national de santé publique du Québec with conducting an exploratory study on the psychosocial effects experienced by workers as the result of four extreme weather events, the frequency of which will be exacerbated by climate change: heat waves, flooding, storms, and forest fires.

Regardless of its nature, a major disaster such as an earthquake, flooding, an ice storm, a nuclear transport accident or an attack can engender a broad range of impacts on individual health and well-being and on the economy and the environment. The authorities usually properly document the immediate effects, especially as regards physical health and economic aspects. However, mental health impacts can be perceived as harder to document.

Individuals who have experienced a disaster…

A survey was conducted among coroners and medical examiners to assess the usefulness of developing a toxicovigilance program.
