As detecting and eradicating transmission foci are fundamental to malaria elimination, appropriate public sector laboratories should consider adopting techniques capable of identifying low-level gametocytaemia. A real-time quantitative nucleic acid sequence-based amplification (QT-NASBA) assay has been used successfully in Africa to determine sub-microscopic gametocyte carriage,  but requires the collection of whole blood.
(Sub)microscopic Plasmodium falciparum gametocytaemia in Kenyan children after treatment with sulphadoxine-pyrimethamine monotherapy or in combination with artesunate.
Prevalence of gametocytaemia was significantly higher (P<0.05) in chloroquine (CQ)-resistant than in CQ-sensitive patients with days 7 and 14 follow up.
Sowunmi and Fateye (2) examined gametocyte carriage and intensities of gametocytaemia in Nigerian children suffering from uncomplicated Plasmodium falciparum malaria treated with antimalarial drugs.
Statistical analysis: Data for normal distribution of gametocytaemia were compared by Student's "t" tests in relation to chloroquine response in sensitive and resistant gametocyte carriage in the years 2000-2001.
The homogeneity of variance was tested with the risk factors for gametocytaemia on days 7 and 14 which revealed that these were highly significant in 1999 [F (2,70) =13.13, P<0.001)], 2000 [F (2,57) = 4.67, P<0.025] and 2001 [F (2, 56) = 6.29, P<0.005] but were insignificantly correlated on days 3 and 5 gametocytaemia during 1999 [F (2,54) = 1.29, P>0.1, 2000: F (2,45) = 0.62, P>0.1 and 2001: F (2,48) = 1.48, P>0.1].
Prevalence of gametocytaemia after treatment with chloroquine showed that the parasitological characteristics with or without gametocytaemia did not show any significant difference, but the duration of illness was longer in comparison to patients without gametocytaemia (2).
Cure rates of clearing gametocytaemia were higher in CQ sensitive than in resistant cases.
