  1. Proportion of mosquitoes infected during human-to-mosquito transmission studies. In two of these studies, the prevalence of submicroscopic carriage among microscopy-negatives was not assessed and therefore this was estimated using the relationship in Fig. 1a.
  2. *Prevalence of submicroscopic carriers estimated.
