Assessing the spatial–temporal relationship between population factors and COVID-19 testing rates in the City of Toronto

Afia Amoako, Mabel Carabalí, Erjia Ge, Ashleigh R. Tuite et autres

Abstract Background The COVID-19 experience in Toronto, Canada, varied over time. However, the focus on spatial and temporal patterns of COVID-19 in the city and associated population factors has mainly been concentrated on case patterns with less exploration of testing. As testing …

Assessing COVID-19 Risk Factors in Toronto Using a Localized Spatio-Temporal Conditional Autoregressive Model

Afia Amoako, Mabel Carabalí, Erjia Ge, Ashleigh R. Tuite et autres

ABSTRACT Purpose Most spatio-temporal models identify COVID-19 sociodemographic and socioeconomic risk factors using methods that assume a single spatial dependency pattern across the city, which may not reflect reality. The purpose of this study is to apply a spatially and temporally localized …

Spatial and Temporal Hotspot Analysis of COVID-19 in Toronto

Afia Amoako, Mabel Carabalí, Erjia Ge, Ashleigh R. Tuite et autres

ABSTRACT The COVID-19 pandemic in Toronto, Canada was unequal for its 2.7 million residents. As a dynamic pandemic, COVID-19 trends might have also varied over space and time. We conducted a spatiotemporal hotspot analysis of COVID-19 over the first four major waves …

Impact of immune evasion, waning and boosting on dynamics of population mixing between a vaccinated majority and unvaccinated minority

David N. Fisman, Afia Amoako, Alison E. Simmons, Ashleigh R. Tuite

BACKGROUND: We previously demonstrated that when vaccines prevent infection, the dynamics of mixing between vaccinated and unvaccinated sub-populations is such that use of imperfect vaccines markedly decreases risk for vaccinated people, and for the population overall. Risks to vaccinated people accrue disproportionately …

Vaccine effectiveness against hospitalization among adolescent and pediatric SARS-CoV-2 cases between May 2021 and January 2022 in Ontario, Canada: A retrospective cohort study

Alison E. Simmons, Afia Amoako, Alicia A. Grima, Kiera R. Murison et autres

BACKGROUND: Vaccines against SARS-CoV-2 have been shown to reduce risk of infection as well as severe disease among those with breakthrough infection in adults. The latter effect is particularly important as immune evasion by Omicron variants appears to have made vaccines less …
