Spatio-Temporal Projection of Covid-19 in Pereira
The current outbreak of coronavirus disease (COVID-19), which was first reported in Wuhan, China on December 31, 2019, has left a balance as of April 19, 2020 of more than 3500000 infected and 160000 deaths in 185 countries. In this work we use a model based on the Markov Microscopic Chain Approach (MMCA) to estimate the spread of COVID-19 in the city of Pereira (Risaralda-Colombia). This model incorporates important aspects of the population related to spatial location within the city which is discretized by communes, mobility between communes, stratification by age groups and separation of individuals into seven epidemiological compartments. This model is used to predict, in a timeline, the incidence of epidemics in geolocated populations, which translates into an indicator tool to take control measures. The data referring to COVID-19, from the municipality of Pereira, until April 20, 2020 are used to feed the model and obtain the spatio-temporal projections. The results presented consider multiple mobility scenarios, so that the flattening of the curves of the different epidemiological compartments can be visualized according to different confinement strategies. As it is a spatio-temporal model, the results of the model can easily be presented as heat over each of the epidemiological compartments, in order to facilitate decision-making processes.
