Ethics approval and consent to participate
: We received ethics clearance from the ethical review committee at Wolaita Sodo University in Ethiopia. The committee justified for verbal informed consent since uneducated or less educated caretakers would face difficulty in reading and comprehending the consent form. Thus informed verbal consent was obtained from the study participants. The parents/caretakers also provided consent on behalf of the children.
: Not applicable.
