By considering the unreported cases used in our SuEIR model, we can infer how many total infectious individuals of COVID-19 are there. In particular, we estimate the prevalence, which is defined as the ratio of total patients (including reported and unreported cases and asymptomatic patients) over the total population. For instance, as of May 22, the prevalence of COVID-19 for California is 9.03%, which means approximately 9.03% Californian have been infected with the coronavirus.
