SEIR model of SARS CoV-2 epidemic in Ethiopia integrating the potential effect of exposure to a SARS-CoV-2 variant with immune escape potential

(A) Topology of compartment model that allows for the infection with the variant of individuals who were exposed to the original virus. (B) Scaled test positivity rate (mapped from the complete country to the individual cities) and seroprevalence. The contribution of different variants is indicated, as well as the proportion of individuals exposed to both. SEIR=susceptible, exposed, infectious, and recovered.
