Please help! Thanks :) 1.Why do scientist want to know how temperature affects West Nile virus transmission?

2. Name two factors that determine how infectious a host is for West Nile virus.

Increased temperatures cause an upsurge in the growth rates of vector populations, decrease the interval between blood meals, shorten the incubation time from infection to infectiousness in mosquitoes, accelerate the virus evolution rate and increase viral transmission efficiency to birds [22,23,30,32,35,36]. The key variables include the normalized weekly numbers of Culex tarsalis mosquitoes, the transmission rate of the virus (temperature-driven), and the feeding pattern of mosquitoes on humans. The statistical analysis shows mosquito numbers to be an important factor in predicting WNV cases.

i was thinking 4.0 v hope this

idk why hjggjhjkhj
