Background
The outbreak of Coronavirus disease, which originated in Wuhan, China in 2019, has affected the lives of billions of people globally. Throughout 2020, the reproduction number of COVID-19 was widely used by decision-makers to explain their strategies to control the pandemic.

In this work, we deduce and analyze both initial and ef...

Background
Throughout the COVID-19 pandemic, human mobility has played a central role in shaping disease transmission. In this study, we develop a mechanistic model to calculate disease incidence from commercially-available US mobility data over the course of 2020. We use it to study, at the US state level, the lag between infection and c...

In this work, we employ a data-fitted compartmental model to visualize the progression and behavioural response to COVID-19 that match provincial case data in Ontario, Canada from February to June of 2020. This is a “rear-view mirror” glance at how this region has responded to the 1st wave of the pandemic, when testing was sparse and NPI measures w...

... The deployment of NPI measures helped to delay the massive growth in cases in nations where such policies were adopted. The use of face masks, along with social-distancing measures, were the first control strategies to restrain SARS-CoV-2 transmission [7,8]. In fact, these fast, standardized, and cost-effective countermeasures were our only line of defense against the spread of COVID-19 incidences until the use of vaccines was approved [9]. ...
... This is a very rough measure, as not all contacts are equal in terms of the risk of infection. For example, a hug between two elderly persons, who are not in the same household and do not have any other risk factors (Fields, 2021), is a far less risky contact than sharing a meal with a friend who is infected with COVID-19. The number of contacts, which we can call contact intensity, is an essential parameter in spreading infectious diseases (Liu, 2022). ...
