Modelo SEIR para avaliação do comportamento da pandemia de Covid-19 em Marabá-PA

Abstract: Objetivo: Determinar o comportamento da curva de casos de COVID-19 em Marabá. Metodologia: Aplicou-se o modelo compartimentado SEIR baseando-se nos dados epidemiológicos locais com os valores estimados de tempo de latência e tempo infeccioso obtido em populações chinesas que foram testadas objetivamente para estimar o desenvolvimento da infecção pelo SARS-CoV-2 em Marabá. Resultados: O primeiro pico apresentou um total de 1438 infectados (28/09/2020) após a documentação do primeiro caso (23/03/2020) demonstran… Show more

“…However, SEIR models proved robust enough to be applied in different geographic locations and in populations of different ethnic origins, enabling and recommending their use in territories with a lack of viral testing. Barbosa et al ( 48 ) applied the SEIR model using epidemiological data from Marabá, a poor municipality in the state of Pará in Brazil, with estimated values of latency time and infectious time obtained in Chinese populations and these proved to be useful for predicting the evolution of COVID-19 cases, a more complex process than the estimation of the vaccine impact. One last important consideration concerning the presented models is that they do not recognize the prolonged duration of the pandemic and the representative rate of deaths during a given period, since they do not use the number of deaths and births in the most active period of the pandemic as parameters, thus, disregarding its vital dynamics, foreseen in the complex systems applied to epidemiological models presented by Lima ( 47 ).…”
