ID503 Malaria - Section 3: Epidemiology and Control

Session 1: Transmission Dynamics and the Epidemiology of Malaria

The concept of vectorial capacity

If you consider only the mosquito factors in Macdonald's equation, you obtain a quantitative index of a mosquito population's capacity to transmit malaria. This is called vectorial capacity, C.

C is defined as 'the number of secondary cases arising per day from one infective case in a susceptible population'.

So, R_{0} is the total number of secondary cases, C is the daily rate at which they arise.

The interactive version of this session includes an interactive version of the vectorial capacity equation.
