Abstract

MASSAD, Eduardo  and  COUTINHO, Francisco Antonio Bezerra. Vectorial capacity, basic reproduction number, force of infection and all that: formal notation to complete and adjust their classical concepts and equations. Mem. Inst. Oswaldo Cruz [online]. 2012, vol.107, n.4, pp. 564-567. ISSN 0074-0276.  http://dx.doi.org/10.1590/S0074-02762012000400022.

A dimensional analysis of the classical equations related to the dynamics of vector-borne infections is presented. It is provided a formal notation to complete the expressions for the Ross' Threshold Theorem, the Macdonald's basic reproduction "rate" and sporozoite "rate", Garret-Jones' vectorial capacity and Dietz-Molineaux-Thomas' force of infection. The analysis was intended to provide a formal notation that complete the classical equations proposed by these authors.

Keywords : vector-borne infections; basic reproduction rate; sporozoite rate; vectorial capacity; force of infection; dimensional analysis.
