Reduction on the number of cases versus reduction on the contact rate, \(1-\xi \), both in percentage. In (a), \(\psi =0.1\) and in (b), \(\psi =0.3\); where \(\psi \) is the fraction of the population tested. Among the 29 municipalities involved in the study, we highlight four of them: Itumbiara, Água Branca, Sobral, and Dourados; the other ones are shown in grey lines.
