Table 3 Parameters used to calculate R0 for the mathematical model

From: Assessment of asymptomatic Plasmodium spp. infection by detection of parasite DNA in residents of an extra-Amazonian region of Brazil

Parameter Estimate Basis for the estimate

M 10,815 specimens/km2 Value obtained from entomological studies carried out in the area [36, 37] and by applying linear regression following Zippin [53]
μ 0.68 Bona and Navarro-Silva [54]
TMH 0.022 Chitnis et al. [55]; Nedelman [56]
THM 0.24 Chitnis et al. [55]; Nedelman [56]
γ 0.0055 (180 days) Value obtained from the observed frequency of asymptomatic individuals and the results reported by Chitnis et al. [55]
b 0.5 Santos [57]; Laporta et al. [58]
q 10 days Chitnis et al. 2008 [55]
p 8 days Santos [57]; Laporta et al. [58]
