Dear User,
You are correct that malaria testing in the Benin 2011-12 DHS was only conducted on a sub-set of children aged 6-59 months. You can find the description of the sample on page 12 of the final report under the section Test de la parasitémie palustre. This section describes that Les tests de parasitémie palustre ont été effectués dans un tiers de l'échantillon sur les enfants de 6-59 mois.
