Professor Jian Lu’s modeling of COVID-19 progression in the United States. The real progression was indicated by the red curve, and the other curves projected the progression at various reduction coefficients, R_c, of the rate of increase of daily cases. This curve indicated that COVID-19 is still not adequately controlled as the red line has exceeded the projected lines of R_c=0.75% and R_c=0.7%. Professor Jian Lu’s models of other countries and of several states in the USA are available at his homepage: http://personal.cityu.edu.hk/jianlu.
