To obtain the simplest nontrivial incubation period, we assume that β(C) =β Θ(C − 1)where Θ(x) is the Heaviside step function -meaning Diverse local epidemics reveal the distinct effects of population density, demographics, climate, depletion of susceptibles, and intervention in the first wave of COVID-19 in the United States that an infected individual is only infectious once they reach stage C = 1, and the infection rate constant is otherwise unchanging. ./cache/cord-177001-ron8oqrn.txt ./txt/cord-177001-ron8oqrn.txt
