  1. a P ov , M s and N0 were varied concordantly to give P f = 0.6 and H bt = 10 d-1 for a 1:4 ratio of humans to animals with A a = 0.004 h-1. b For a three day feeding cycle, and for a negligible searching-related mortality these values correspond to an average daily survival of 0.84, 0.87, 0.90, 0.94, respectively cPeriod from mosquito bite to infectious gametocytes, not to presence of symptoms
