In December 2019, a global pandemic started with origin in Wuhan (China), it is a coronavirus disease caused by SARS-CoV-2. It was rapidly spread throughout the world due to its infectious nature. In order to curb this pandemic, each of the affected countries imposed epidemiological measures such as territorial and population confinement, which led to the paralysis of some countries, leaving behind a major economic crisis. For the prediction of the evolution of different epidemics in populations, there are several epidemiological mathematical models based on differential equations, such as SIR, SIS, SIRS, SEIS, SEIR, MSIR and MSEIR. However, in spite of not being the model best adapted to the expansion of COVID-19, the SIR model is the one used in the present work and the most widely used both for its simplicity and for being one of the first models to be formulated. It consists of different differential equations that study the transmission of the virus by dividing the population into three groups, susceptible, infected and recovered.In the present work, four different scenarios are carried out with the aim of finding the model that best fits the evolution of the pandemic suffered in the Spanish territory during the first wave. Finally, a SIR model, established for the dates corresponding to January 1 to April 19, 2020, has been the one that best fits this evolution and that has provided the best results.
