摘要: Introduction: The Covid-19 pandemic is one of the biggest public health crises world has ever faced In this context, it important to have effective models describe different stages epidemic's evolution in order guide authorities taking appropriate measures fight disease Objective: To present an analysis epidemic curves based on phenomenological growth models, with applications for cumulative numbers confirmed cases infection by novel coronavirus (Sars-Cov-2) and deaths attributed (Covid-19) caused virus, Brazilian cities Recife Teresina Methods: Richards generalized model were used make numerical fits respective empirical Results: described very well against which they tested particular, was able identify appearance inflexion point curves, turn represents peak daily A brief discussion also presented relationship between fitting parameters obtained from mitigation adopted each municipalities considered Conclusions: proved be describing estimating epidemiological parameters, such as time curve deaths, thus allowing a practical efficient monitoring Introducao: pandemia da e uma das maiores de saude publica que o mundo ja enfrentou Nesse contexto, importante ter modelos eficazes para descrever os diferentes estagios evolucao epidemia, fim orientar autoridades competen- tes na adocao politicas publicas enfrentamento mesma Objetivo: Apresentar analise curvas epidemicas com base em fenomenologicos crescimento, tomando como exemplo acumuladas casos confirmados infeccao pelo novo obitos atribuidos doenca causada cidades do Metodos: Foram utilizados modelo generalizado crescimento fazer ajuste numerico respectivas empiricas Resultados: Verificou-se descrevem muito bem foram testados Em capaz identificar razoavel confiabilidade surgimento ponto infle- xao nas acumuladas, qual corresponde ao maximo diarias Apresenta-se ainda breve discussao sobre relacao entre parâmetros obtidos no medidas mitigacao adotadas retardar propagacao cada um dos municipios considerados Conclusoes: O mostrou-se bastante eficaz es- timar epidemiologicos importantes, pico diarios, permitindo assim realizar modo pratico eficiente monitoramento epidemia
