Table 1 Characteristics of study children and paired malaria infections

Characteristic	Total episodes	Asymptomatic episodes	Symptomatic episodes
Number of episodes	228	114	114
Number with first presentation for each category	114	54	60
Age at time of sample collection (mean) (years)	7.00	7.02	6.98
Duration between episodes (mean) (days)	118	121	115
Parasite density (geometric mean)	9080/μl	3767/μl	14,390/μl

For each child, paired asymptomatic and symptomatic infections were studied, regardless of which presentation occurred first. For duration between episodes, the times shown are means for episodes preceded by a prior episode in the other category
