Relation between age and parasitaemia according to the type of hemoglobin. Six genotypes were identified during the studies. Parasitaemia were defined as the number of parasites per microliter as counted on Giemsa stained thin smears [12]. a Repartition of parasitaemia according to the type of hemoglobin; no significant difference was observed. b Percent of people harboring a level of parasitaemia, according to the normal (Nhb) or abnormal (aNHb) type of hemoglobin; percent are calculated separately for each group. c Percent of people harboring normal (Nhb) or abnormal hemoglobin (aNHb) according to age
