Distribution of Th2R haplotypes across seasons, age groups, and clinical and non-clinical <i>Plasmodium falciparum</i> infections.

<p>The prevalence of each unique Th2R haplotype that was present in at least 10% of all 454 reads of a given sample was calculated and stratified by the malaria transmission season in which they were collected, by three age groups (age≤5, age 6–10, and age≥11), and whether or not they were derived from samples that came from clinical vs. asymptomatic infections. Haplotype distributions did not vary significantly by age group, study year, or presence of clinical symptom for either Th2R or Th3R, with the exception of the 3D7 haplotype, which had a significantly greater prevalence in the oldest age group compared to the youngest age group (p<0.03).
