Combined average proportions of total WNV RNA comprised of competitor RNA after competition against a marked reference virus in chicks or mosquitoes.

1 = input is the inoculum.2 = output is either day 2 chick serum or day 7 whole mosquito homogenate.3 = p-value was determined in an unpaired t-test between input and output for each cohort (significance is defined as p≤0.05 and is noted in bold).
