However, we were able to closely reproduce the dynamics of the first wave of pandemic COVID by setting an aggressive slope of social distancing (i.e., self-quarantine, use of masks, avoidance of public gatherings) as well as an aggressive testing campaign (~0.98). In addition, SIR-related models do not explicitly account for the active infective role of asymptomatic individuals. Indeed, Mexico has been regarded as one of the countries that have conducted a low number of tests. 2) describes the rate at which infected patients are retrieved from the infective population.

Actual data points, as officially reported, are shown using black circles. We used a set of differential equations, recent epidemiological data regarding the evolution of COVID-19 infection, and basic information on the characteristics of COVID-19 infection (i.e., time from infection to recovery, case mortality rate) to accurately recreate or predict the progression of the COVID-19 in three urban areas with different demographic characteristics (i.e., NYC in USA, Daegu in South Korea, and Mexico City in Mxico). According to reports from Daily Mail, The Independent and Evening Standard, a Microsoft Excel spreadsheet containing laboratory results reached its maximum size, meaning that as many as 15,841 .

The relevance of wide-scale testing to control the progression of COVID-19 in urban areas has been discussed widely in literature. Colors are also associated with the economic and recreational activities that are allowed and the level of social distancing enforced. Mathematical modeling may (and probably should) become a much more available tool in the case of public health emergenciesone ideally widely available to practically any citizen in any of our societies. This model may be extremely valuable for government officials who must predict, with high fidelity, the progression of an epidemic event to better design their action strategies.

A second term relates to the recovery or death of infected patients (symptomatic or asymptomatic) and is represented by the integral of all infected subjects recovered or deceased from the onset of the epidemic episode in the region, considering a delay of 21days (delay_r), which accounts for the average time of recovery of an infected individual. Biosecur. The use of trade names and commercial sources is for identification only and does not imply endorsement by the Centers for Disease Control and Prevention or the U.S. Department of Health and Human Services.

We found that, adapting the model to a particular locality is straightforward and only requires (a) the declaration of the population of the urban area, and (b) the selection of a td value (time to doubling the name of infections) or o (initial infective rate); (ln 2=o td). Kucharski, A. J. et al. Our simulations predict that the total number of cases positive for COVID-19 would have exceeded 1.3 million in the absence of social distancing measures during the first 100days of the epidemic.
