Abstract:
 The goal of this work is to analyze the effects of control policies for the
 coronavirus (COVID-19) epidemic in Brazil. This is done by considering an
 age-structured SEIR model with a quarantine class and two types of controls.
 The first one studies the sensitivity with regard to the parameters of the basic
 reproductive number R0 which is calculated by a next generation method.
 The second one evaluates different quarantine strategies by comparing their
 relative total number of deaths.
