Social distancing has a clear buffering effect on the epidemics, delaying the occurrence of the peak of infections and distributing the number of cases across a longer time span. By Whitney Tesi. JAMA https://doi.org/10.1001/jama.2020.2565 (2020). Each row in the data has a date. Similarly, we multiplied by (1)=0.50 to simulate the effect of a scenario of social distancing that would diminish close social interaction by 50% (see Supplementary Fig. The second equation (Eq. This means that, to properly fit the actual data on cumulative cases and new infections per day (Fig. Simulation predictions are described by the yellow line. Res.

Med. Figure3 shows the predicted trend of the pandemic in NYC during the initial stage of the pandemic wave from March to May, 2020. Simple modifications will enable the use of this model for the evaluation of the effect of different vaccination strategies. PCR-based testing in the USA started in mid-March (i.e., mainly NYC) and increased rapidly to more than 100,000 PCR tests daily. By contrast, as of December 2020, the USA and South Korea had conducted 688 and 71.65 tests per 1000 inhabitants (https://ourworldindata.org/coronavirus)50. This virus is a coronavirus called SARS-CoV-2. For instance, as the cumulative infected population progresses, the susceptible population (PoX; total population minus infected individuals) is reduced. Both tools allow you to estimate the potential effectiveness of each of the three strategies, the average number of contacts per case, and the time needed for case interviews and contact tracing follow-up activities. & Hsueh, P.

In the current version of our model, asymptomatic patients are considered part of the population capable of transmitting COVID-19; reported evidence that suggests that asymptomatic subjects (or minimally symptomatic patients) may exhibit similar viral loads25 to those of symptomatic patients and may be active transmitters of the disease5,26,27.

The results of our simulations suggest that strict measures of social distancing had to be rapidly implemented in NYC during the first weeks of the pandemic episode and that the measures of social distancing imposed in NYC were equivalent to a decrease in the effective demographic density of more than 70% (>0.70) in a few days.

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. Outdated Excel spreadsheets caused thousands of positive Covid-19 tests The first equation of the set (Eq. Choi, S. C. & Ki, M.

Indeed, we have been able to observe exemplary responses from some Asian countries (i.e., China5, South Korea6, and Singapore7), some highly aggressive responses in Europe (i.e., Germany and Switzerland8), and several delayed or not so effective responses from other regions (i.e., USA, England, Italy and Spain)9,10.

Finally, the model can be easily adapted to epidemic events related to any other viral or bacterial pathogen by inputting the corresponding epidemiological parameters. For instance, using this simple model, virtually any citizen could assess, in real time, the efficacy of the actions of her/his society in the face of an outbreak. The number of retrieved patients should be interpreted as the number of individuals that have been retrieved from the general population and are not contributing to the propagation of COVID-19.

Our analysis suggests that the sudden increase in the slope of the number of daily new cases that has been observed by the end of 2020 was originated by a progressive relaxation of the social distancing (i.e., a linear change in the values form 0.75 to 0.68 during 150days).

The selection of o (td) can be easily done by fitting the prediction to the initial set of reported cases of infection. We determined the appropriate ranges of values for o by analyzing publicly available data from different websites that continuously monitor the progression of confirmed cases of COVID-19 for different nations (Table 2). Learn more about the efficacy of disinfectants on strains and variants of coronavirus.

Colors are also associated with the economic and recreational activities that are allowed and the level of social distancing enforced. FDA Sentinel System's Coronavirus (COVID-19) Activities. Our selection of a=0.85 is based on a recent large-scale serological study conducted in New York City (NYC) to find anti-SARS-CoV-2 antibodies among the population and a computational model27. Another fraction of infected subjects (1) is not effectively retrieved from the population until they have recovered or died from the disease. Demographic elements are directly integrated into the model (Po, total population). Mexico City went from red to orange in June 2020 and back to red in December 2020. We set (Po=8,350,000) and selected a value of o=0.655 (td=1.058) for the first week of this simulation. Phys. The percentage of asymptomatic infections during pandemic Influenza A/H1N1/2009, based on epidemiology studies founded in serological analysis in a vast range of geographical settings, has been estimated between 65 and 85%31; up to 2040% of the population in urban areas (i.e., Monterrey in Mxico, and Pittsburgh in USA)32,33 exhibited specific antibodies against Influenza A/H1N1/2009regardless of experiencing symptoms, while the fraction of confirmed symptomatic infections was lower than less than 10%. Modeling the pandemic evolution in South Korea was more challenging than that in NYC. Biosecur. In turn, this implies a lower demand for hospital beds per day during the epidemics and may mark the difference between a manageable crisis and a public health catastrophe9, 47.
