Population Level Prevention and Containment Strategies

This research area will focus on informing the most efficient and effective prevention, and containment of the virus, including closing and re-opening strategies, understanding the interactions between various strategies, and compliance with prevention containment strategies in different settings, and among different population groups.  Analysis should consider the required conditions for various stages of closing and re-opening, the interdependencies, and the health and well-being impacts of closing and re-opening.

Key Challenge Questions:

  1. What are the unintended consequences of the COVID-19 prevention and containment measures in Ontario and their associated impact?

  2. What are the most effective prevention and containment strategies to maintain opening of various sectors (including daycares, various levels of school and various business sectors)?

    1. What is the ideal mix of prevention and containment strategies?

    2. What are the most cost-effective prevention and containment strategies?

  3. What are the factors to consider in determining whether to close or re-open various sectors (e.g., returning to Stage 1 or 2)?

  4. What are the key factors influencing compliance/adherence with prevention and containment strategies?

    1. Are there mitigating population characteristics that may inform compliance/adherence strategies, but also function to undermine them, that should be considered with any strategies?

  5. What are the most critical factors influencing COVID-19 transmission at schools or daycares? Does school classroom characteristics/size influence COVID-19 spread? If so, how?

  6. Is there an optimum number of case manager/contact tracers required to effectively trace and isolate all new COVID-19 cases and their close contacts? What is the number required for each position in relation to new cases each day?

Please consider: All analyses should include consideration of population sub-groups, for example: sex, gender, and sexual orientation; people with high risk clinical characteristics; people with physical and/or mental health disabilities; Indigenous peoples and communities; immigrants and refugees; ethno-racial communities; Francophone communities; linguistic communities; religious/faith communities; homeless people; people living on a low income; people receiving social assistance; people using drugs; and people living in rural/remote or inner urban areas.
