Table 5 Exogenous variables considered in the infectious disease models

From: Modelling entomological-climatic interactions of Plasmodium falciparum malaria transmission in two Colombian endemic-regions: contributions to a National Malaria Early Warning System

Exogenous variable Used variable Depending on Default value
Human Biting Density ma or HBD [blood-meals/person/night]   Total mosquitoes captured (indoor and outdoor landing captures 06:00–09:00 pm)
Sporozoite Rate s or SR [dec]   0.07–0.12
Human susceptibility (efficiency with which an infective mosquito infects a susceptible human) S_H [dec]   1.00
Mosquito susceptibility (efficiency with which an infective human infects a susceptible mosquito) S_V [dec]   1.00
Proportion of infective female vectors (proportion of those anophelines with sporozoites in their salivary glands which are actually infective) b [dec]   0.01
Recovery rate in man C1 [dec]   1.00
Transmission rate f [1/days] f (Risk) (G)
  1. (G) The parameter Transmission Rate f is dependent on the average number of mosquitoes-bites on humans and measures the level of interaction between both populations. For a community in a low risk area of malaria f is set to 0.13; for an intermediate risk f is set to 0.17; and for a high-risk f is set to 0.25. This parameter can also be dependent on temperature (vectorial capacity), SEC (bed-nets and deforestation), and climate anomalies (El Niño event) [21].
