  1. Seropositivity and seroconversion rates (SCR) are presented for P. falciparum and P. vivax. If the best model to fit the age-adjusted seropositivity data was one with a change point in transmission, the SCR before the change point is indicated as λ1, while the SCR after the change point is indicated with λ2
  2. aFor 17 individuals age data was missing, therefore total numbers in the ‘all ages’ group differ slightly from those presented in the separate age categories
