A simple deterministic model for bancroftian filariasis transmission dynamics.

A differential equation model for bancroftian filariasis transmission dynamics is developed. Fluctuations of the mosquito vector population are related to environmental variables such as climate and vector control operations. Prevalence in the mosquito population and mean worm burden in the human population are considered. The behaviour of the model is compared with epidemiologic and entomological data from Pondicherry (South India). The model enables one to make predictions on the effect of future control operations.
