Plasmodium infectivity rate to mosquitoes that fed on falciparum malaria patients treated with a single dose of primaquine. Day zero refers to the percent of oocyst positive mosquito fed on patients before the treatment. Sixteen of each line represents the oocyst positivity of mosquitoes feeding on single patients immediately before treatment and afterwards. Mosquitoes fed on two patients after 10 days of treatment were oocyst positive [19, 20, 23–25].
