I wanted to enquire about the QVR and QEVR compartments. I understand the QVR compartment represents the group of individuals that are under quarantine (among other things, i.e. vacc and prev infection). Given they're under quarantine, should the lambda term they're subjected to be lamq instead of lam?

The terms in dQVRdt (1 below) and dQEVRdt (2 below) would then balance (from L1029 of comoOde.cpp, here) and would be in line with other transitions (i.e. QV -> QEV, QR -> QER, QS -> QE).

      arma::vec dQVRdt = quarantine_rate*VR
                        - (1.0-vaccine_eff_r)*lam%QVR  // <--------------------- 1
                        - vac_dur_r*QVR
                        - omega*QVR
                        + ageing*QVR
                        - mort_col%QVR 
                        ;

      arma::vec dQEVRdt = quarantine_rate*EVR
                        - gamma*QEVR
                        + ageing*QEVR
                        - mort_col%QEVR
                        - (1.0/quarantine_days)*QEVR
                        + (1.0-vaccine_eff_r)*lamq%QVR // <--------------------- 2
                        ;

Thanks for the advice.
