Table 1 Gametocyte density, prevalence and proportion of mosquitoes infected for the three infection groups: clinical disease, asymptomatic detectable infection and asymptomatic undetectable infection, and contribution to the infectious reservoir (total infectivity weighted by body surface area).

From: Assessing the impact of next-generation rapid diagnostic tests on Plasmodium falciparum malaria elimination strategies

Compartment and percentage of total infected population Gametocyte densities (parasites per microlitre) of gametocytaemic individuals (median and interquartile range) Proportion of individuals in compartment that are gametocytaemic (by QT-NASBA) Percentage of mosquitoes infected by all the individuals in compartment Contribution to infectious reservoir
Clinical disease (4.4%) 290.9 (181.7, 1,169.7) 100% 23.1% 9.0%
Asymptomatic detectable (42.2%) 89.2 (15.6, 490.1) 87% 12.7% 62.3%
Asymptomatic undetectable (53.4%) 29.8 (1.9, 128.6) 59% 3.9% 28.7%
  1. The clinical disease group consists of the 4.4% of individuals who have the highest parasite densities. Asymptomatic detectable individuals are those that are detectable by QT-NASBA and microscopy, and the asymptomatic undetectable individuals are those detectable by QT-NASBA, but not microscopy.
