Parameters

Description

Point estimates

a

Human feeding rate: Number of bites on human, per mosquito, per day, i.e., the product of the number of bites per mosquito per day and the proportion of bites on humans.

0.4 day-1

b

Parasite transmission probability of mosquitoes to humans: The probability that an infectious mosquito transmit the parasite to a human from a single bite.

0.6

c

Parasite transmission probability of humans to mosquitoes: The probability that a mosquito become infected from a single bite on an infectious human.

0.5

ν

The rate that an infected human becomes positive for malaria parasite: An inverse of latent period.

1/18 day-1

P

Treatment coverage: The proportion that infected humans receive the malaria treatment
