Abstract: Choi and Severo (1988) proposed an estimator as an approximation to the maximum likelihood estimator of the infection rate of the simple epidemic model. It is shown that this estimator can be regarded as an approximation to the martingale estimator which is optimal in the sense of Godambe (1985). This idea is readily extended to an epidemic model allowing removal to produce an estimator of the infection rate.
