Fig. 2From: Assessment of asymptomatic Plasmodium spp. infection by detection of parasite DNA in residents of an extra-Amazonian region of BrazilSchematic representation of the basic reproductive rate (R0) for the study region estimated using the mathematical model proposed by Anderson and May [51] (filled diamond). Only factors related to the vector are taken into account. The solid line represents the threshold for R0 = 1. The dashed line indicates how much the vector population should increase to reach this thresholdBack to article page
