Table 2. Parameters of the full co-infection model.

Parameter Definition Baseline value Details
Inline graphic Biting rate (number of bites taken per vector per day) 0.2–0.5 days−1 Parameter varied to assume vectors bite on average once every 2 to 5 days
Inline graphic Birth rate of humans 1/18,250 days−1 Equal to host death rate to ensure constant population size
Inline graphic Birth rate of vectors 1/10Inline graphic days−1 Equal to vector death rate to ensure constant population size
Inline graphic Death rate of humans 1/18,250days−1 Assumes host average life expectancy of 50 years
Inline graphic Death rate of worms 13/37500 days−1 [39]
Inline graphic Death rate of microfilariae 1/300 days−1 [39]
Inline graphic Death rate of vectors 0.1 days−1 Approximate mortality at 25°C [56]
Inline graphic Probability of infectious vectors transferring infection to susceptible hosts 1/25 [57]
Inline graphic Probability of infectious hosts transferring infection to susceptible vectors 9/100 [57]

Inline graphic Rate of development from immature to L3 larvae 0.08 days−1 Development rate of [58] evaluated at 25°C
Inline graphic Rate at which infected hosts become infectious 1/10 days−1 [57]
Inline graphic Rate at which infected vectors become infectious 0.02 days−1 Evaluation of Inline graphic at T = 25°C (where Inline graphic for P. falciparum) [34]
Inline graphic Rate at which humans return to susceptible from recovered 1/7 days−1 Host population assumed to experience loss of immunity within 1 week

Inline graphic Proportion of L3 leaving mosquitoes that enter host 0.0003 [39], [59]
Inline graphic Death rate of larvae 0 days−1 Larval mortality assumed to arise only due to vector mortality
Inline graphic Additional mortality rate of larval-infected vectors with malaria status Inline graphic 0.1 days−1 Uncertain parameter varied in sensitivity analysis (but within bounds to ensure realistic vector mortality at 25°C)
Inline graphic Probability of mf entering the vector upon biting an LF-infected host 0.37 [39]
Inline graphic Probability of mf entering the vector developing into L3 larvae 1 [39] [25]
Inline graphic Force of immunity (strength of immune response) 0.2 [39], [59]
