Variability associated with differences in the asexual parasitaemia detection threshold for a secondary infection detected by active detection of infection. Panel a shows normalized probability densities for the infection-to-detection period IDPA as a function of the detection threshold (asexual parasites per μL of blood). Panel b shows normalized probability densities for the SI given an untreated primary case as a function of the corresponding IDPA distributions from a
