Model-based evaluation of transmissibility and reinfection for the P.1 variant of the SARS-CoV-2
Renato Mendes Coutinho,Flavia Maria Darci Marquitti,Leonardo Souto Ferreira,Marcelo Eduardo Borges,Rafael Lopes Paixão da Silva,Otavio Canton,Otavio Canton,Tatiana P. Portella,Silas Poloni Lyra,Caroline Franco,Mateusz M. Plucinski,Fernanda C. Lessa,Antônio Augusto De Moura Silva,Roberto André Kraenkel,Maria Amélia de Sousa Mascena Veras,Paulo Inácio Prado +15 more
TL;DR: In this article, the authors used a model-based approach to estimate P.1 parameters of transmissibility and reinfection by maximum likelihood, and found that the new variant transmissability was about 2.5 times higher (Confidence Interval (95%CI): 2.3-2.8) compared to the previous variant in Manaus.

Renato Mendes Coutinho,Flavia Maria Darcie Marquitti,Leonardo Souto Ferreira,Marcelo Eduardo Borges,Rafael Lopes Paixão da Silva,Otavio Canton,Tatiana P. Portella,Silas Poloni,Caroline Franco,Mateusz M. Plucinski,Fernanda C. Lessa,Antônio Augusto Moura da Silva,Roberto André Kraenkel,Maria Amélia de Sousa Mascena Veras,Paulo Inácio Prado +14 more
TL;DR: Coutinho et al. as discussed by the authors used a model-based approach, fitting data from the national health surveillance of hospitalized individuals and frequency of the P.1 variant in Manaus from December-2020 to February-2021.
Journal ArticleDOI
Local Moebius transformations applied to omnidirectional images
TL;DR: This work presents a new method to transform omnidirectional images based on a combination of Moebius transformations in the complex plane and weighting functions that restrict the action of these mappings to regions of interest.
Journal ArticleDOI
Brazil in the face of new SARS-CoV-2 variants: emergencies and challenges in public health
Flavia Maria Darcie Marquitti,Renato Mendes Coutinho,Leonardo Souto Ferreira,Marcelo Eduardo Borges,Tatiana P. Portella,Rafael Lopes Paixão da Silva,Otavio Canton,Silas Poloni,Caroline Franco,Verônica Coelho,Lorena Barberia,Monica de Bolle,Alexandra Crispim Boing,Maria Rita Donalisio,Antonio Fernando Boing,Antônio Augusto Moura da Silva,Paulo Inácio Prado,Maria Amélia de Sousa Mascena Veras,Roberto André Kraenkel +18 more
TL;DR: In this article, the epidemic situation of Covid-19 in Brazil, in the face of the emergence of a new strain called P.1, which is more transmissible and may be associated with reinfection, is discussed.
Journal ArticleDOI
Assessing the best time interval between doses in a two-dose vaccination regimen to reduce the number of deaths in an ongoing epidemic of SARS-CoV-2
Leonardo Souto Ferreira,Otavio Canton,Rafael Lopes Paixão da Silva,Silas Poloni,Vítor Sudbrack,Marcelo Eduardo Borges,Caroline Franco,Flavia Maria Darcie Marquitti,José Cássio de Moraes,Maria Amélia de Sousa Mascena Veras,Roberto André Kraenkel,Renato Mendes Coutinho +11 more
TL;DR: A novel extended age-structured SEIR mathematical model that includes a two-dose vaccination schedule with a between-doses delay modelled through delay differential equations and linear optimization of vaccination rates finds that the best strategy depends on an interplay between the vaccine production rate and the relative efficacy of the first dose.
