The Ross/Macdonald classic transmission parameters and their four elemental combinations to characterize dynamics.

(a) The classic Ross/Macdonald parameters and their units.		(b)The basic four unitless transmission parameters.
m	Ratio of mosquitoes to humans	$R_{0} = \frac{m a^{2} b c e^{- g n}}{r g}$	The basic Reproductive number
a	Host feeding rate (bites per mosquito per unit time)	$γ = a c / g$	Number of bites in a mosquito’s
b	Transmission efficiency, infectious host to mosquito		lifetime that infects it
c	Transmission efficiency, infectious mosquito to host	$β = m a b / g$	Number of infecting bites per
$g^{- 1}$	Average mosquito lifetime (time)		host in a mosquito lifetime
n	extrinsic incubation period (time)	$P_{e} = e^{- g n}$	Probability a mosquito
$r^{- 1}$	Host infectious period (time)		survives incubation latency
