Vasconcelos, Giovani L.; Macêdo, Antônio M. S.; Ospina, Raydonal; Almeida, Francisco A. G.; Duarte-Filho, Gerson C.; Souza, Inês C. L.In this technical note, we present a brief discussion of the main results reported in our paper “Modelling fatality curves of COVID-19 and the effectiveness of intervention strategies”, MedRxiv/2020/051557 (DOI:10.1101/2020.04.02.20051557). In that paper, we applied the Richards growth model (RGM) to describe the fatality curves of the COVID-19 disease for countries that were, up to April 1, 2020, near the end ...
Germany's 'coronavirus anomaly': Statistical evidence that early mass testing l...
Vasconcelos, Giovani L.; Macêdo, Antônio M. S.; Souza, Inês C. L.; Ospina, Raydonal; Almeida, Francisco A. G.; Duarte-Filho , Gerson C.; Holm, ChristianIn this note, we present a statistical analysis of the mortality rates of COVID-19 for several selected European countries. We compare the countries' mortality rates with their respective number of tests as a function of the time since the first death. Our analysis shows that countries that either delayed mass testing, such as Italy, or have not fully adopted it, such as France and the UK, have had much higher ...
Analysis of Covid-19 epidemic curves via generalized growth models: Case study ...
Vasconcelos, Giovani L.; Duarte-Filho, Gerson C.; Brum, Arthur A.; Ospina, Raydonal; Almeida, Francisco A. G.; Macêdo, Antônio M. S.Introduction: The Covid-19 pandemic is one of the biggest public health crises the world has ever faced. In this context, it is important to have effective models to describe the different stages of the epidemic’s evolution in order to guide the authorities in taking appropriate measures to fight the disease. Objective: To present an analysis of epidemic curves of Covid-19 based on phenomenological growth model...
OVERVIEW OF THE COVID-19 IN NORTHEAST BRAZIL: ANALYSES AND FORECASTS VIA GROWTH...
Vasconcelos, Giovani L.; Brum, Arthur A.; Duarte-Filho, Gerson C.; Ospina, Raydonal; Almeida, Francisco A. G.; Macêdo, Antônio M. S.The Covid-19 pandemic, caused by the new coronavirus (SARS-CoV-2), is one of the gravest public health crises the world has ever faced. In this context, it is important to have effective models to describe the different stages of the epidemic, in order to offer guidance to the competent authorities regarding the adoption of public policies to contain and control the pandemic. In this work, we present a novel me...

Duarte-Filho, Gerson C.; Brum, Arthur A.; Ospina, Raydonal; Almeida, Francisco A. G.; Macêdo, Antônio M. S.; Vasconcelos, Giovani L.In this Technical Note we analyze the cumulative curves of deaths attributed to Covid-19 in the 26 Brazilian states and the Federal District until August 21, 2020. Mathematical growth models implemented by the ModInterv Covid-19 application, which can be accessed via internet browser or via a mobile app available at the Google Play Store, were used to investigate at which stage the epidemic is in each of these ...
