Problem

A mild seasonal influenza strain circulating among the well-mixed crew of a remote research station has R0=1.2R_0 = 1.2, close to the epidemic threshold. Solve the final-size relation r∞=1−e−R0r∞r_\infty = 1 - e^{-R_0 r_\infty} for the fraction of the crew eventually infected, to three significant figures.
