Publication: Basic reproduction number for vector-borne diseases: impact of assumptions on EIP duration
Researchers have shed light on the impact of assumptions for the duration of the extrinsic incubation period (EIP) when modelling the dynamics of vector-borne diseases.
Writing in Vector-Borne and Zoonotic Diseases, they report: “Mathematical modeling and notably the basic reproduction number R0 have become popular tools for the description of vector-borne disease dynamics.
“We compare two widely used methods to calculate the probability of a vector to survive the extrinsic incubation period. The two methods are based on different assumptions for the duration of the extrinsic incubation period; one method assumes a fixed period and the other method assumes a fixed daily rate of becoming infectious.
“We conclude that the outcomes differ substantially between the methods when the average life span of the vector is short compared to the extrinsic incubation period.”
