COVID-19 simulation models are mathematical infectious disease models for the spread of COVID-19. [1] The list should not be confused with COVID-19 apps used mainly for digital contact tracing . Note that some of the applications listed are website-only models or simulators, and some of those rely on (or use) real-time data from other sources.
The modelling can help decide which intervention(s) to avoid and which to trial, or can predict future growth patterns, etc. History. [edit] The modelling of infectious diseases is a tool that has been used to study the mechanisms by which diseases spread, to predict the future course of an outbreak and to evaluate strategies to control an ...
The Reed–Frost model is a mathematical model of epidemics put forth in the 1920s by Lowell Reed and Wade Hampton Frost, of Johns Hopkins University. [1] [2] While originally presented in a talk by Frost in 1928 and used in courses at Hopkins for two decades, the mathematical formulation was not published until the 1950s, when it was also made into a TV episode.
Compartmental models in epidemiology. Compartmental models are a very general modelling technique. They are often applied to the mathematical modelling of infectious diseases. The population is assigned to compartments with labels – for example, S, I, or R, (S usceptible, I nfectious, or R ecovered). People may progress between compartments.

June 22, 2001. (2001-06-22) – June 23, 2001. (2001-06-23) Operation Dark Winter was the code name for a senior-level bio-terrorist attack simulation conducted on June 22–23, 2001. [1][2][3][4] It was designed to carry out a mock version of a covert and widespread smallpox attack on the United States. Tara O'Toole and Tom Inglesby of the ...
The first American case was reported on January 20, [9] and Health and Human Services Secretary Alex Azar declared a public health emergency on January 31. [10] Restrictions were placed on flights arriving from China, [ 11 ] [ 12 ] but the initial U.S. response to the pandemic was otherwise slow in terms of preparing the healthcare system ...
The CDC publishes official numbers of COVID-19 cases in the United States. The CDC estimates that, between February 2020 and September 2021, only 1 in 1.3 COVID-19 deaths were attributed to COVID-19. [2] The true COVID-19 death toll in the United States would therefore be higher than official reports, as modeled by a paper published in The ...
