These strategies are important to evaluate in order to understand the epidemiological impact of reopening schools, businesses, and society. However, more detailed models are needed to evaluate scenarios based on complex intervention strategies. Numerous statistical models and data visualization tools have been developed over the last year in an attempt to meet this demand, with varying purposes, structures, and levels of detail and complexity for example, despite their limitations, data dashboards have proven crucial for understanding the current state of the epidemic on both global and local scales. Since the onset of the pandemic, mathematical modeling has been at the heart of informing this decision-making. More than a year after COVID-19 was first identified, governments continue to be faced with an urgent need to understand the rapidly evolving pandemic landscape and translate it into policy. In partnership with local stakeholders, Covasim has been used to answer policy and research questions in more than a dozen countries, including India, the United States, Vietnam, and Australia. Covasim is open-source, written in Python, and comes with extensive documentation, tutorials, and a webapp to ensure it can be used as easily and broadly as possible. These interventions include physical interventions (mobility restrictions and masks), diagnostic interventions (testing, contact tracing, and quarantine), and pharmaceutical interventions (vaccination). While Covasim can be used to explore theoretical research questions or to make projections, its main purpose is to evaluate the effect of different interventions on the epidemic. Covasim can be tailored to the local context by using detailed data on the population (such as the population age distribution and number of contacts between people) and the epidemic (such as diagnosed cases and reported deaths). In this paper, we describe a COVID-19 model, called Covasim (COVID-19 Agent-based Simulator), that we developed to help answer these questions.

Mathematical models have played an important role in helping countries around the world decide how to best tackle the COVID-19 pandemic.
In collaboration with local health agencies and policymakers, Covasim has already been applied to examine epidemic dynamics and inform policy decisions in more than a dozen countries in Africa, Asia-Pacific, Europe, and North America. Implemented in pure Python, Covasim has been designed with equal emphasis on performance, ease of use, and flexibility: realistic and highly customized scenarios can be run on a standard laptop in under a minute. These interventions can incorporate the effects of delays, loss-to-follow-up, micro-targeting, and other factors. Covasim also supports an extensive set of interventions, including non-pharmaceutical interventions, such as physical distancing and protective equipment pharmaceutical interventions, including vaccination and testing interventions, such as symptomatic and asymptomatic testing, isolation, contact tracing, and quarantine.
Covasim includes country-specific demographic information on age structure and population size realistic transmission networks in different social layers, including households, schools, workplaces, long-term care facilities, and communities age-specific disease outcomes and intrahost viral dynamics, including viral-load-based transmissibility.
Here we describe the methodology of Covasim (COVID-19 Agent-based Simulator), an open-source model developed to help address these questions. The COVID-19 pandemic has created an urgent need for models that can project epidemic trends, explore intervention scenarios, and estimate resource needs.
