We propose a second-order harmonic model to describe circadian periodicity in the 24-h cycle of microfilarial counts. Rhesus monkeys (Macaca mulatta) were infected with Brugia malayi. Definite evidence of circadian periodicity was found in the microfilarial counts. The estimates of the parameters, periodicity indices and peak hours were determined.
